The Mitsubishi Delica are a range of trucks and vans built by Mitsubishi since 1968. It absolutely was originally based on a small vehicle launched the prior seasons, also known as the Delica, their name a contraction associated with English words term Delivery automobile. This truck, and a commercial van produced from this has obtained many brands in export areas, for sale due to the fact L300 (later L400) in Europe, Jamaica (stopped after the third generation) and unique Zealand, Express and Starwagon in Australia, and ordinary Mitsubishi Van and truck in the US. The passenger automobile variations were referred to as Delica celebrity truck from 1979 before 1994 introduction for the Delica room Gear, which became just room equipment in Europe at the least. The newest variation (unavailable as a commercial automobile) is named the Delica D:5. With the exception of the 4th generation, all five years will always be offered in several international markets.
In Japan, the Delica Cargo nameplate is utilized on badge-engineered Mazda Bongos between 1999 and 2010. Since 2011, the Delica D:2 name has-been placed on a rebadged Suzuki Solio.
The Delica show is changed in Summer 1979 by an all new design, bringing total width to the most 1,690-millimetre (67 in) dictated by Japanese regulations for "compact" vehicles. Suspended at the front end by an unbiased wishbone building and a leaf spring at the back, the Delica also features a sliding side door and single-piece petrol strut tailgate. The line-up ended up being extended to add ten design variations encompassing a wide variety of traveler (eight seats in a three/two/three setup), cargo and leisure applications. A four-wheel drive alternative had been offered in 1982, an initial in Japanese van markets. Machines were all four-cylinders famous from MMC's traveler vehicles and included the 1,439 cc, 80 PS (59 kW) Saturn (4G33) and 1.6-liter Saturn (4G32) motors. A 1.8-liter Sirius (4G62) variation producing 100 PS (74 kW) appeared in May 1980, and a 2.0-liter Sirius (4G63B) petrol version became optional in 4WD models from November 1983. A 2.3-liter Astron (4D55) diesel starred in October 1982 and ended up being replaced because of the larger 2.5-liter Astron (4D56) in 1986.
The four-wheel drive type of the Delica was first introduced on Japanese marketplace in October 1982. This functional automobile used a changed form of the Mitsubishi Pajero's chassis, albeit generally with modest motors (originally just the 1.8-liter fuel). After the introduction regarding the third generation Delica, the truck (split taxi) version of the next generation always been built until 1994. Japanese people were accountable for greater amounts of yearly road income tax as a result of larger motors put in in higher trim levels plans.
Advertising And Marketing
Australian Continent
Chrysler Australian Continent launched the SA show Delica to the Australian marketplace on 14 April 1980 beneath the title "Chrysler L300 Express" after debuting on Adelaide Motor Show in 12 April. After acquiring control over the Chrysler Australia procedures in identical thirty days, Mitsubishi engines rebranded the company Mitsubishi Motors Australian Continent in October 1980. This resulted in the rebranding of the L300 Express as a Mitsubishi. Fitted with a 1.6-liter engine and four-speed handbook, both van (three-seater commercial) and wagon (eight-seater) variants were offered, with all the commercial (van) variation offered with or without part back windows. The utility (pickup) variation was not marketed in Australia, whilst the L200 Express covered that part associated with the market. In November 1981 the SB show was launched, now fitted with radial ply tires on larger diameter rims, therefore increasing the payload ability from 925 to 1,000 kilograms (2,039 to 2,205 pound). These thirty days, Mitsubishi introduced the high-roofed luxury "Deluxe" trim, installed with electric sunroof and cloth upholstery. The following upgrade towards SB series found its way to October 1982, causing the "Deluxe" trim being renamed "Starwagon" and getting a bigger 1.8-liter engine---offered with a five-speed overdrive handbook or optional three-speed automated. The "celebrity truck" (this is written either together or as two words) moniker was also applied to examples assembled by Todd engines in brand new Zealand, albeit because of the 65 PS (48 kW) 1.6-liter engine. Mitsubishi offered the accessibility to the 1.8-liter motor to your lower-specification variations, albeit in automatic guise best. The 1.8 has also been for sale in the lengthy wheelbase, large roofing, panel van variation.
From might 1983, the L300 Express obtained rectangular headlights in chrome surrounds as part of the SC version. The SC also featured recently created black colored resin bumpers and changes into forward suspension springtime price to improve trip and handling. The four-wheel drive version, badged "4WD", emerged in October 1983 as a 1.8-liter model with floor-mounted five-speed guide just, consequently becoming a seven-passenger model by losing the front-row center seat. After another facelift in October 1984, the car became the SD series, launching better equipment and black headlight surrounds along side a black trim section involving the headlights on "Starwagon" and "4WD" trims. The SD modification also enhanced the "4WD" to a 2.0-liter motor, with all the 1.8-liter standard problem in a new long-wheelbase commercial (van) model. A final small modify, the SE series starred in 1986.
Asia
This generation is manufactured in the Philippines since 1987 whilst the "Mitsubishi L300 Versa Van" (stopped in April 2012) along with the Cab/Chassis variant in which neighborhood coach builders assemble rear body for passenger and cargo hauling needs. Variations including the FB (families business), dog (individual and equipment transport), WT (water tight aluminum van) and DS (drop part) have been made to cater to those wants. This season, a protracted backside body variation the FB variant labeled as the Exceed was added. In 2014, neighborhood truck body manufacturer Centro production established a minibus type of the L300 known as the XV Mikrobus. Its built on the FB Exceed system and it is meant to be used as a public utility automobile, a school bus, or an ambulance. It is also meant to restore the Versa Van and to become an alternative to the FB variant. In 2017, Mitsubishi engines Philippines launched your L300's diesel engine will likely be up-to-date to conform to the DENR's and LTFRB's EURO-4 standardization task.
This generation continues to be in manufacturing in Indonesia while the "Mitsubishi Colt L300", designed with the 2.5-liter 4D56 diesel engine. A gasoline system was also readily available for a short period, but as a result of decreased need, was stopped. Since 2010, Isuzu Indonesia posses offered this 2nd generation Delica whilst the Isuzu Bison---available in pickup and minibus versions with an Isuzu Panther-sourced 4JA1L 2.5-litre diesel motor with 80 PS (59 kW). The Bison costs a little more than a corresponding L300.
In South Korea, Hyundai built the 2nd generation Delica whilst the "Hyundai Porter", changing an earlier model with the same title. South Korean creation of this Porter proceeded alongside the 3rd generation Delica, which was advertised by Hyundai because the "Grace". This Porter had been replaced by an indigenously developed third generation Porter in March 1996.
From 1997 to 2000, the vehicle was marketed by Mahindra & Mahindra in India as "Mahindra Voyager", but listed too much it had been removed from production after just a little over 2 yrs. The Voyager performed talk with some success as an ambulance, but this relationship best further avoided prospective private purchasers. Distinctive on Mahindra Voyager is the fitment of PSA's 2.5-liter XD3P diesel engine, creating 72.5 PS (53 kW) DIN at 4000 rpm.
In Summer 1986 the Delica underwent its third full design changes. Much more aerodynamic than earlier versions, its monocoque body and considerable safety features shown remarkably popular in Japan's fast-growing leisure vehicle markets segment. The greater curved build ended up being described as "soft cube" styling by Mitsubishi. Traveler models continued to be sold as Delica celebrity Wagons, which became just simple "Starwagon" in Australian Continent. The commercial variation is known as the "Express" in Australia. Two wheelbases were offered. In 1990, the Australian marketplace obtained the obviously aspirated diesel system as an alternative; this is initial Delica so furnished because market.
Even though the subsequent L400 Delica and Delica Space equipment are launched in 1994, production of the L300 Starwagon continuing when it comes to Japanese market until 1998. The L300 Delica (van models best) also remained in production for export areas. These export markets got a facelift in 1999, revealed in September of this year in Australian Continent. In Japan the commercial Delica range is replaced by a badge-engineered Mazda Bongo under an OEM offer which began in November 1999.
In-may 2013, Mitsubishi stopped the commercial type of the third generation Delica in Australia---badged while the Mitsubishi Express because of its inferior safety---the Express is the final brand-new car become sold in Australian Continent with a one-star ANCAP rating. The Express had changed bit because it got a minor model change in 2003.
A big selection of engines were offered, from a 1.4-liter around a 2.4-liter petrol, and a 2.5-liter diesel and turbodiesel, plus a 2.6-liter obviously aspirated diesel. Rear- or four-wheel drive, a number of bodystyles as well as 2 different wheelbases made for an especially substantial line-up. The four-wheel drive framework ended up being considering that of the modern Mitsubishi Pajero, although areas were seldom interchangeable. Belated basic export markets variations gotten a carburetted 16-valve type of the 2.0-liter 4G63 four-cylinder, with 116 hp (87 kW) at 6,000 rpm.

Asia
Cargo variations are built because of the Asia engine Corporation in Taiwan. This generation Delica has also been built under license by Hyundai of South Korea, where it was labeled as the "Hyundai elegance" or "Hyundai H-100" in certain Eurasian areas. Launched in December 1986, this variation initially received the twin headlights as used in the united states marketplace variations, but after a front-end renovation the newest more aerodynamic variation received thinner plus rounded headlights. This version is known as the "unique elegance". Both 2.4-liter fuel and 2.5-liter turbodiesel inline-four motors are offered, both Mitsubishi designs. Hyundai language led to the 4D56 diesel motor becoming rebranded D4BX / D4BA.
The United States
From 1987 until 1990, Mitsubishi sold this model in little data in the United States while the "truck" for traveler variations and "Van" for windowless cargo models. The US variations all obtained a 107 horsepower (80 kW) version of the 2.4-liter 4G64 motor. For model ages 1990 and 1991 an LS form of the truck was added. Taiwanese-produced CMC Delica vans can be bought in Mexico as Dodge 1000 by July 2007. The Mitsubishi Expo LRV changed the Van/Wagon in 1992.
During the early 2000s enthusiasts began importing the popular van to Canada. The 4WD turbo diesel van is also a standard option for Canadian postal staff which need a right give drive automobile.
Since 2007, the Cargo variations built because of the Asia engine organization in Taiwan become shipped to Mexico wearing Dodge badges.
United Kingdom
Introduced for 1987, the British marketplace got the newest L300 with either the 1.6- petrol or 2.5-liter diesel motor. Both wheelbases had been readily available.
1994--1996
Revealed on 12 might 1994, the most recent Delica received significantly more aerodynamic bodywork. No vehicle design ended up being readily available for this generation, and traveler brands are now called Delica area Gear within the domestic Japanese marketplace. Body requirements regarding the room Gear in Japan ranged from XR, XG, Exceed, Super Exceed and Royal Exceed, and both long and short-wheelbase variations are readily available.
Mitsubishi Delica Area Gear Chamonix (Japan)
The 4th generation Delica is dependant on the motor and transmission regarding the Mitsubishi Pajero but unlike the Pajero of its time was of monocoque construction and does not have a separate framework yet still features complete off roadway capability, with four-wheel drive, large and lowest proportion gears and differential locking. This has system variants from 2.5 liters to a 2.8-liter intercooled turbodiesel. A 2.4-liter and a 3.0-liter V6 petrol or gasoline engine with 12 or 24 valves, each with 4 gears and overdrive. In addition to the 2.8-liter diesel design these are typically readily available as a two or a four-wheel drive version.
In many export markets, the cargo models associated with the fourth generation had been labeled as the Mitsubishi L400 even though the passenger versions were called Mitsubishi room equipment -- without using the Delica nameplate at all.
In South Korea, Hyundai put the Mitsubishi Delica whilst the base car for the Hyundai Starex (A1) manufactured between 1997 and 2007.
In Australia, this generation, referred to as WA show was for sale in both cargo (Mitsubishi Express) and passenger (Mitsubishi Starwagon) variations. The Starwagon ended up being available between September 1994 and 2003. The Express launched on top of that, but continued on until 2005. To distinguish the semi-bonneted WA Express from less expensive, previous generation SJ show that marketed alongside they, the WA products had been disambiguated utilizing the "Walk-Thru" designation.
The Australian Starwagons had been made available in four amounts of specs: GL, GLX, GLS and 4WD. Mitsubishi fitted the GL with a 2.0-liter carburetored inline-four, with all the GLX getting a fuel-injected 2.4-liter inline-four, together with GLS a 3.0-liter V6. Both four-cyliner machines are fitted standard with a five-speed guide transmission with recommended four-speed column-shift automatic. The 3.0-liter GLS supplied a four-speed floor-mounted automatic as its only transmission alternative. The renovation design, released in 1996 spotted the product range rationalised with only the base GL and mid-range GLX brands retained.
1996--2007
In 1996, the Delica had been enhanced with a facelift model. The improvement is mainly aesthetic with changes to the lights groups and front bodypanel, with the integration of a moulded bumper instead of the first three section bullbar. The engine is upgraded with an electric controls type circulation type jet pump and a digital sidestep was made standard from the greater specs models.
Your final facelift premiered in Japan in August 2002.
2005--2008 Taiwan renovation
In Taiwan, the next generation Delica stayed created and sold whilst the 4th generation Delica is simply named the Mitsubishi area Gear, and had been situated above the 3rd generation design. Preliminary models associated with the area gear produced and sold in Taiwan had been the same as the series 2 Japanese renovation. However, in 2005 your final renovation was conducted exclusively in Taiwan with lesser adjustment complete into the grilles, front side and back bumpers, and front side and rear light products.
The engines's bore and stroke both measure 86.0 mm, which designers make reference to as square. Based on Mitsubishi, the newest cylinder dimensions contribute to a free-revving personality (max energy at 6,500 rpm), linear energy shipping and wide torque bend. Mitsubishi utilized a timing chain in place of a belt for best reliability and iridium spark plugs to reduce emissions also to assist offer biggest services intervals for lower cost of ownership. To cut back body weight, Mitsubishi put a plastic cam cover and intake manifold and double-layer metal exhaust manifold. The fatigue manifold has actually a rear place in the transverse engine, when compared to front place when it comes to past motor, yielding important pros like best emissions performance. To lower vibration, Mitsubishi put a 4-point inertial axis system with cylindrical hydraulic motor mounts regarding the remaining and correct sides. A lightweight, high-rigidity squeeze-cast aluminium bracket regarding right side mount (engine side) lowers motor noise under speed. A lightweight, high-rigidity metal dish bracket on left side mount (transmission part) lowers equipment noise. A custom-tuned insulator originated for the front side and rear mounts to aid get a handle on both idle vibration and acceleration shock.

Goal: remove, inspect, clean and reinstall (or replace) the idle air control valve (IACV) on a Mitsubishi Delica L300 — explained step‑by‑step for a beginner mechanic, with full component descriptions, theory, common failures and testing. I’ll cover gasoline engines (which use an IACV) and note diesel differences so you don’t waste time looking for a part that isn’t there.
Short summary first: The IACV meters extra air around the throttle plate so the engine can hold a steady idle. If it’s dirty or electrical parts fail, the idle will be rough, too high, low, or the engine may stall. Cleaning the IACV and its seat often fixes the problem; if electrical parts are bad you’ll replace the valve.
Safety first
- Work in a well‑ventilated area. Throttle cleaner is flammable and toxic. Wear gloves and safety glasses.
- Do this with the engine cold or cooled down to avoid burns.
- Disconnect the negative battery terminal if you will be removing electrical connectors for a prolonged time (this will reset some ECU memories). For short inspections you can leave battery connected but be careful not to short anything.
- Avoid spraying throttle cleaner on electrical connectors, wiring, sensors, or painted surfaces.
Does your Delica L300 have an IACV?
- Gasoline engines (e.g., 4G63/4G64 family or 4G54 depending on year) typically have an IACV mounted on the throttle body or intake plenum.
- Many diesel Delica L300s (4D56) do not have a conventional IACV; idle is controlled mechanically or by fuel/ECU via different components (idle speed control valve or electronic governor). Check visually: if the throttle body area has a small cylindrical valve with an electrical plug and 2–3 bolts, that’s the IACV.
What the IACV is and how it works (with analogy)
- Analogy: think of the throttle plate as the main faucet controlling how much water (air) flows when you open it. At idle the throttle is nearly closed — the engine still needs a small, steady trickle of air. The IACV is a small secondary faucet (controlled by the ECU) that meters that trickle of air around the closed throttle plate so the engine can maintain a steady idle under different loads (AC on, charging, cold engine).
- Components:
- IACV body: the housing that mounts to the throttle body and contains the moving element.
- Pintle/arm/plate (moving element): the piece that moves in and out to open/close the bypass passage. On stepper motors it’s a small plunger; on solenoids it’s a valve needle.
- Electrical connector/wiring: supplies power and control signals from the ECU. Signals may be PWM, stepper pulses, or simple on/off current.
- Mounting bolts and gasket: secure the valve and seal the bypass passage. Replace the gasket if damaged.
- Throttle body / intake manifold interface: the IACV controls bypass air that enters downstream of the throttle plate into the intake manifold.
- ECU: senses engine speed, temperature, load and commands the IACV to position itself for correct idle.
- Feedback (sometimes): the ECU may use engine RPM and TPS (throttle position sensor) to decide how to drive the IACV.
- Theory of operation: When more idle airflow is needed (cold start, AC compressor load, alternator load), the ECU opens the IACV more. When less is needed (warm engine, no load), it closes it. If the valve sticks or the ECU can’t control it electrically, the idle will be unstable.
Common symptoms of a failing IACV
- High idle or low idle that doesn’t correct after warming up.
- Idle surges/stumbles or RPM hunting.
- Stalling at idle, particularly on cold start or when accessories engage.
- Check engine light with codes like P0505 (ISC system malfunction) or related throttle/IAC codes (actual code numbers vary by ECU).
- Excessive smoke on cold start (if mixture is affected), though that can be other issues too.
Tools & materials
- Basic hand tools: ratchet, socket set (common sizes 8–12 mm), screwdrivers.
- Torque wrench (recommended). If not available, snug bolts evenly; typical small bolt torque ~7–12 Nm (5–9 lb‑ft) but check manual if possible.
- Throttle body / carburetor cleaner (use a cleaner safe for O‑rings and electronics; “throttle body cleaner” or “intake cleaner”) and lint‑free rags or new toothbrush. Don’t use carb cleaner with harsh acids.
- Small pick or dental pick for gasket removal (careful).
- Multimeter (for electrical testing).
- Replacement gasket (recommended) and replacement IACV if cleaning doesn’t fix it.
- OBD reader (optional) to read/clear codes and monitor RPM/commands.
Step‑by‑step procedure (remove, inspect, clean, test, reinstall)
1) Locate the IACV
- Find the throttle body on the intake. The IACV is typically bolted to the side of the throttle body or intake plenum. It’s a small cylindrical/oval housing with an electrical plug and 2–4 mounting bolts.
2) Prepare and document
- Let engine cool. Remove battery negative terminal if you want to avoid any accidental shorts and/or will be unplugging connectors for longer.
- Take a photo of the connector and hoses (if any) before removal so you can reinstall correctly. (No yapping — just useful.)
3) Disconnect the electrical connector
- Depress the tab and pull the connector off. Don’t pull on wires. Inspect the connector for corrosion, bent pins, or broken wires. Clean lightly with contact cleaner if needed.
4) Remove the IACV
- Remove the mounting bolts (usually small metric bolts). Keep them in a safe place.
- Gently pull the IACV straight out. It will have a gasket; note how it sat. Don’t gouge the mating surfaces.
5) Inspect components
- Gasket: if cracked, flattened, or damaged, replace.
- Valve pintle and bore: look for carbon build‑up, sticky varnish, grime. If the pintle or bore is pitted or very corroded, replace the valve.
- Throttle bore around the throttle plate: carbon here can affect idle too — inspect throttle plate and bore for deposits.
- Wiring and plug for corrosion/damage.
6) Clean the IACV and mating surface
- Use throttle body/intake cleaner and a lint‑free rag or toothbrush to remove carbon. Spray cleaner on rag/toothbrush rather than directly into electrical openings.
- Gently work carbon off the pintle and bore. For tight areas use a soft brush and cleaner. Avoid scratching sealing surfaces.
- If the valve uses a rubber or soft seal, be extra gentle.
- Clean mating surface on throttle body and remove old gasket material completely.
7) Electrical testing (quick checks)
- Resistance: set multimeter to ohms. Check resistance across the valve’s terminals. Typical values vary widely by type; you are checking for open circuit (infinite resistance) or short (near zero). If open or shorted, replace the valve. If you have specs from a service manual, compare exact values.
- Power test at connector (engine off, key ON): with connector back on or carefully back-probing, you should see battery voltage on supply pins when ignition is ON (exact pins vary). Be careful; don’t crank while back‑probing. If no supply voltage, issue may be wiring/fuse/ECU.
- Ground: check ground continuity to chassis.
- Bench/functional test: some IACVs should move when voltage/ground pulses are applied — only do this if you know the valve type and safe method. Incorrect application can damage it; if unsure, skip bench power testing and rely on resistance and visual inspection.
8) Reinstall (or install replacement)
- Use a new gasket or carefully reuse a perfect gasket. Ensure surfaces are clean.
- Insert valve, align and start bolts by hand to avoid cross‑threading. Tighten evenly. Torque to spec if you have it; otherwise tighten snugly (small bolts, don’t overtighten). Typical small IACV bolts: 7–12 Nm (5–9 lb‑ft).
- Reconnect electrical connector. Reconnect any vacuum hoses if present. Reconnect battery negative if removed.
9) Clear codes and idle relearn
- If you have an OBD reader, clear any idle or throttle-related codes.
- Idle relearn: modern ECUs adapt automatically after driving. A common simple method: start engine and let it warm up to operating temperature with no accessories on, letting it idle for several minutes. Turn on AC and observe RPM; it may rise briefly as ECU compensates. If idle still unstable, perform any dealer-specified relearn procedure (some vehicles require turning key on/off cycles or a controlled idle procedure). For Delica L300, usually letting it idle and driving normally will allow the ECU to re-adapt.
10) Verify repair
- Start engine, let it reach normal temp. Observe idle stability with AC on/off, headlights on/off, and during transitions (blipping throttle). Verify no idle surges, no stalling, and no relevant check engine lights. Scan for pending codes.
What can go wrong (failure modes)
- Carbon build‑up / sticking pintle: most common. Causes sticking open or closed. Symptoms: erratic idle, surging, stalling.
- Electrical failure: broken coil, open circuit or shorted windings. Symptoms: no response, codes, erratic control.
- Wiring/connector corrosion: intermittent operation or no power. Symptoms: intermittent idle problems, codes.
- Vacuum leaks at gasket or mating surface: extra air bypass causes high idle or roughness. Symptoms: high idle, lean condition.
- Mechanical damage: bent pintle, worn bore — requires replacement.
- ECU or sensor faults (TPS, coolant temp sensor): if ECU receives wrong inputs it may drive IACV incorrectly; diagnosing these sensors may be required.
Diagnostic tips (if cleaning doesn’t solve)
- With IACV removed, try running engine (if safe) briefly to see idle behavior — note this only for experienced people and take extreme care. More practical: test wiring and check for power to the connector with ignition ON.
- Check TPS (throttle position sensor). If TPS reads slightly open when closed, ECU may think throttle is open and close IACV, causing low idle or stalling.
- Check engine coolant temp sensor: if it reports cold, ECU may keep IACV open for higher idle.
- Check for vacuum leaks around intake manifold, hoses, EGR, PCV system.
When to replace instead of clean
- Electrical resistance out of spec, open winding or short between windings.
- Heavy pitting or corroded mechanical parts.
- Valve does not move even after cleaning and wiring/power confirmed.
- Rebuild/replace if cleaner doesn’t remove stuck carbon or if internal seals are damaged.
Useful troubleshooting examples
- Symptom: rough idle only when cold — likely carbon build or ECU idle strategy; clean IACV and allow warm‑up.
- Symptom: sudden loss of idle when AC kicks on — IACV failing to open under load or wiring problem.
- Symptom: idle hunts up and down — could be sticking valve, vacuum leak, or faulty sensor input.
Final notes
- Don’t spray cleaner directly into the wiring connector or onto sensors (TPS, MAF).
- Replace gasket whenever the IACV is removed unless it’s brand new and undamaged.
- Keep the throttle body and throttle plate reasonably clean — a dirty throttle plate can mimic IACV problems.
- If you replace the IACV, keep the old one as a reference so you can compare connectors/pins and confirm the new part is correct.
This procedure should cover a typical IACV service on a Mitsubishi Delica L300 gasoline engine. If your Delica has a diesel 4D56 and you can’t find an IACV on the throttle body, look for an idle speed control valve assembly or consult a service manual for the diesel idle system — diesels use different components and procedures.
