Mitsubishi Renault F9Q1 F9Q2 engine factory workshop and repair manual download

- Safety first
- Park on level ground, set parking brake, chock wheels, work with engine cold to avoid burns, wear gloves and eye protection, keep loose clothing and jewelry away from moving parts.

- What “choke cable” means here (brief)
- Choke cable is a mechanical cable that pulls a choke lever to richen mixture for cold starts on carburetted engines or operates a cold-start device; many modern Renault F9Q engines are diesel/common-rail and do not have a traditional choke — if yours is fitted with an aftermarket or older-style cold-start cable, the instructions below apply to locating, adjusting, lubricating, or replacing that cable.

- Basic tools you already have (detailed descriptions and how to use)
- Slotted (flat) screwdriver: flat blade that fits screw slots — use to pry small clips, open retaining tabs, or turn flat-head screws; apply pressure on handle with controlled force, keep blade centered in slot to avoid slipping.
- Phillips screwdriver: cross-shaped tip for Phillips screws — use matched-size tip to avoid stripping heads; hold perpendicular and turn with steady pressure.
- Long-nose (needle-nose) pliers: tapered jaws for gripping small parts, bending cotter pins, removing clips, pulling cable ends — squeeze handles gently and use pointed tips for precise work in tight spaces.
- Slip-joint (adjustable) pliers: wider jaws for gripping larger objects and turning small nuts if a wrench isn’t available — adjust jaw opening before gripping to avoid crushing parts.
- Adjustable wrench (crescent): adjustable jaw for turning nuts and bolts where specific-size spanners aren’t available — set jaw snug on fastener and pull rather than push where possible to prevent slipping.
- Socket set with ratchet (recommended if you have it): offers better leverage and access for nuts/bolts than wrenches; use appropriate socket size, pull ratchet toward you to loosen/tighten with control.
- Wire cutters / diagonal cutters: cut zip-ties, cable ties, or trim frayed cable ends.
- Penetrating oil (e.g., WD‑40 or similar): soaks into seized linkages and makes stuck fittings easier to free — spray on, wait a few minutes, then work the part.
- Light (work lamp or phone torch): illuminates engine bay so you can see cable routing and fasteners clearly.
- Rags and small container: keep parts and grime contained and wipe hands/parts as you go.

- Additional tools you may need and why
- Replacement choke cable kit (if replacing): contains inner cable, outer sheath, ferrules/ends, and sometimes mounting grommet — required when cable is frayed, stretched, rusted, seized, or outer sheath damaged.
- Cable lubricator (or thin oil and an applicator): pushes lubricant through cable housing to restore smooth motion — necessary if cable is stiff but not broken.
- Small pick or awl: to remove old rubber grommets or free stuck cable ends from levers without damaging parts.
- Torx/Allen keys (if applicable): some vehicles use Torx/Allen fasteners on dash controls or linkage brackets — required only if your fasteners use those heads.
- Heat-shrink tubing or new grommets: to seal holes and protect cable from chafing if old rubber is perished.
- Zip-ties and small clamps: secure cable away from hot/moving parts after routing.

- How to inspect before adjusting (what to look for)
- Trace the cable from the control knob (dash or knob) to the choke lever on the carburettor/throttle body, noting routing, mounting clips, and any sharp bends.
- Check outer sheath for cracks, cuts or crushed sections; test inner cable movement by pulling control — should move smoothly with no sticking.
- Inspect cable ends/ferrules for corrosion or fraying; inspect choke lever for play or seized pivot; look for missing grommets where cable passes bulkhead.

- How to adjust a choke cable (step-by-step actions)
- Locate the cable adjustment point at the choke lever or at a locknut on the cable housing near the carburetter/throttle body.
- Loosen the locknut or retaining clip (use appropriate wrench or pliers) so the housing can slide but the inner cable remains engaged.
- Pull the inner cable from the control end (dashboard or lever) until there is just enough tension that the choke lever fully moves to the closed (choke-on) position when the control is pulled, but not so tight that it holds the choke closed at rest.
- While holding the inner cable to maintain the correct tension, slide the housing back and tighten the locknut or refit the retaining clip to lock the housing in place.
- Cycle the control several times and watch the choke lever travel through its full range; ensure it opens fully when released and closes fully when pulled; if travel is limited, reevaluate routing and remove any obstructions.
- Re-secure any mounting clips and replace any grommets or rubber seals you disturbed.

- How to free/stiffen a sticky cable (maintenance)
- Spray penetrating oil or cable lubricant into the exposed housing ends and work the inner cable in and out to distribute lubricant; repeat several times.
- If movement improves, push lubricant along the length with a cable lubricator or by applying thin oil and moving the cable repeatedly until smooth.
- Replace the cable soon if lubricant doesn’t restore smooth operation; sticky cables fail unpredictably.

- How to replace a choke cable (if inspection shows it’s required)
- Remove the control knob from the dash (usually pulls off or has a retaining clip/screw).
- Disconnect inner cable from choke lever: remove cotter pin or unhook end from lever pivot with pliers/pick.
- Remove any retaining clips or grommets securing sheath at firewall or bracket; pull the old cable out from dash to engine bay.
- Compare old cable to replacement to confirm length, end fittings, and sheath type match; some kits include a bulkhead grommet and ferrules — necessary for a proper fit.
- Feed the new cable from the dashboard end through the same routing to the engine bay, ensuring it passes through the firewall grommet and clips without sharp bends.
- Attach the inner cable end to the choke lever per original orientation, fit ferrules and grommets, and secure sheath into mounting bracket.
- Adjust cable tension as described in the adjustment steps, then test full operation and smooth return.
- Trim any excess inner cable if needed and secure with a ferrule or small clamp; do not leave frayed ends.

- When replacement is required and which parts to buy
- Replace the cable if inner wire is broken, frayed, heavily corroded, outer sheath cracked/crushed, or lubrication fails to free it.
- Buy a direct-fit replacement cable for your vehicle/model if available; if F9Q1/F9Q2 is diesel without factory choke, check whether aftermarket cold-start or manual choke kit was fitted and match that part number.
- If unsure, buy a universal choke cable kit with correct length and fittings plus a firewall grommet and ferrules; ensure inner wire and end fittings match original.
- Replace ancillary parts if damaged: rubber firewall grommet to prevent chafing, retaining clips/mounting bracket, choke lever pivot if worn or seized.

- Testing after repair or replacement
- With engine off, cycle choke control and observe lever travel and return; expect smooth, full travel without binding.
- Start engine cold and operate choke per normal behaviour (only if your engine actually uses choke) — verify that choke operates as intended and returns as engine warms.
- Re-check fasteners and routing after a short drive.

- Quick troubleshooting pointers
- If control moves but choke lever doesn’t: check broken inner cable or detached end ferrule.
- If lever sticks in position: inspect seized pivot or cable rubbed/caught on bodywork; free pivot and lubricate.
- If cable moves but lever only partially: cable length mismatch or wrong end fitting — replace with correct part.

- Final notes
- If your F9Q engine is diesel/common-rail and does not have a choke, don’t install a choke system; identify the actual cold-start system (glow plugs, thermostatic devices) and consult a service manual for those procedures.
- Replace worn parts rather than repeatedly adjusting a failing cable — replacement restores reliable starting and avoids cable failure while driving.
