Toyota Hilux 2005-2013 factory workshop and repair manual download

- Purpose and quick note
- Accelerator linkage = throttle cable and mechanical connections between the gas pedal and the throttle body/carburetor. The procedure below covers inspection, lubrication, adjustment and replacement for mechanical (cable) systems found on many Toyota Hilux models. If your Hilux has an electronic throttle (no cable / "drive-by-wire"), do not attempt mechanical cable work — electronic systems require dealer/diagnostic service.

- Safety first (do these every time)
- Park on level ground, engine off, keys out, parking brake engaged, wheels chocked.
- Work with the engine cold to avoid burns.
- Wear safety glasses and gloves to protect hands and eyes.
- If you will disconnect electrical connectors or sensors, disconnect the negative battery terminal to avoid accidental shorting.

- Tools — descriptions and how to use each
- Combination wrench set (metric, 8–17 mm typical)
- Description: one side open-end, one side box-end; useful for holding nuts/bolts in tight spaces.
- How to use: select the size that fits snugly on the nut/bolt, pull to tighten/loosen; use box-end for more torque; use open-end to access confined angles.
- Socket set with ratchet (metric sockets 8–17 mm) and extensions
- Description: ratchet handle plus sockets for hex fasteners; extensions reach recessed bolts.
- How to use: choose correct socket, push onto ratchet, place on bolt head, turn ratchet handle to loosen/tighten; use extension where bolts are recessed.
- Screwdriver set (flat and Phillips)
- Description: various tips for screws and for prying small clips.
- How to use: match tip to screw head, apply steady pressure; use flat blade carefully to lever off retaining clips.
- Pliers: needle-nose and slip-joint
- Description: needle-nose for small clips/pins; slip-joint for gripping and bending.
- How to use: use needle-nose to remove cotter pins, clips and hold small parts; slip-joint to grip nuts or cable ends.
- Locking pliers (Vise-Grips)
- Description: can clamp and lock onto parts for extra grip.
- How to use: clamp onto stubborn parts or hold throttle linkage while loosening fasteners; release by lever.
- Adjustable wrench (crescent)
- Description: single adjustable jaw fits various sizes.
- How to use: set jaw to fit nut snugly, avoid rounding corners; use as backup tool.
- Penetrating oil (e.g., PB Blaster, WD-40 Specialist)
- Description: lubricant that loosens rusted/stuck nuts and bolts.
- How to use: spray on seized fasteners, wait 10–15 minutes, then attempt to loosen with socket or wrench.
- White lithium grease or light cable lubricant
- Description: grease for pivot points; cable lubricant for inner cable sliding.
- How to use: apply a small amount to pivot joints and run cable lube down the cable sheath then work the pedal to distribute.
- Replacement throttle cable (OEM or quality aftermarket) — if needed
- Description: the entire cable assembly including ends and adjuster.
- How to use: install per vehicle routing, secure ends at pedal and throttle body, adjust tension.
- Small flashlight or inspection lamp
- Description: illuminates dark engine bay areas.
- How to use: shine into throttle body and cable routing to inspect for wear or damage.
- Pick set or small pry tool
- Description: thin tools to remove retaining clips and grommets.
- How to use: gently pry out clips or separate the cable from brackets.
- Replacement small parts (if needed): retaining clips, cotter pins, throttle return spring
- Description: hardware that secures cable ends and provides return force.
- How to use: replace any broken clips/pins with same-size parts; install return spring so throttle snaps back.

- Extra tools you might need and why
- Torque wrench
- Why: to torque throttle-body or bracket bolts to factory spec if you remove them; not strictly necessary for simple cable adjust but recommended for reassembly.
- Heat source (propane torch) — advanced use only
- Why: to free extremely rusted bolts; use with caution and not near flammable fluids.
- Multimeter / diagnostic scanner
- Why: only if you suspect electronic throttle or throttle position sensor issues. For cable systems, not required.

- Inspection procedure (what to look for)
- Visual inspection of entire cable length for fraying, kinks, rust, worn sheath or binding points.
- Check cable ends for missing or deformed ferrules, broken clips or stretched adjuster threads.
- Verify throttle return spring is present and gives strong snapback when pedal released.
- Operate pedal by hand and observe throttle linkage at throttle body—should move smoothly, return fully when released.
- If you see frayed wire, seized inner cable, broken return spring, or excessive slack that cannot be adjusted, replacement is required.

- Adjustment procedure (basic steps)
- Locate the adjuster: usually at the throttle body end or along cable near the firewall (barrel nut or threaded adjuster with lock nut).
- Loosen the lock nut (use two wrenches: one to hold adjuster, one to turn lock nut) so the adjuster can be turned.
- With the pedal released, back off or turn the adjuster until you achieve minimal free play — general target is about 2–5 mm (about 1/16–3/32 inch) of pedal free travel before the throttle begins to open. (Exact spec varies by year; 2–5 mm is a safe general guideline.)
- Tighten the lock nut while holding the adjuster in position so adjustment doesn’t move.
- Test pedal: press firmly and release several times, ensure throttle returns smoothly and there’s no binding.
- Start engine and confirm idle stable and accelerator response smooth over full travel. If idle changes or throttle hangs, recheck return spring and adjuster.

- Lubrication and freeing seized parts
- Spray penetrating oil on any rusted adjuster nuts, pivot bolts and cable bracket fasteners; wait, then remove.
- Apply light cable lubricant down the sheath at the top and bottom of the cable, operate pedal to draw lube into inner cable.
- Grease pivot points lightly with white lithium grease — do not over-grease throttle body bore.

- Replacement — when required and what to replace
- Replace throttle cable assembly if:
- Cable is frayed, inner wire broken, heavily rusted, kinked or inner cable seized so lubrication and adjustment cannot restore smooth action.
- Cable ends or ferrules are damaged or snapped.
- Replace return spring if:
- Spring is weak, stretched or broken and throttle doesn’t snap back quickly.
- Replace retaining clips/cotter pins if:
- Original hardware is corroded, deformed or missing.
- Replace throttle body/linkage components if:
- Linkage arms are bent, pivot holes worn oversized, or throttle shaft is excessively worn or sticking.
- What parts to buy:
- OEM or exact-fit aftermarket throttle cable for your Hilux year and engine — buy by vehicle year, engine code and transmission where applicable.
- Throttle return spring kit if original is corroded (match size and tension).
- Small hardware kit: retaining clips, cotter pins, locknuts.
- If throttle body parts are damaged, order OEM throttle body/linkage or rebuild kit as appropriate.

- How to replace a throttle cable (general)
- Remove pedal end: access under dash, unclip cable from pedal lever (remove a retaining clip or pin).
- Remove cable from firewall grommet and any routing clips.
- At engine bay, remove cable end from throttle lever and unbolt any bracket that secures cable.
- Pull old cable out along routing; compare new cable length and ends to confirm fit.
- Feed new cable through same routing, secure grommet at firewall, attach engine end to throttle lever and pedal end under dash, fit any clip/pin.
- Adjust cable tension as described above.
- Double-check routing so cable is not rubbing sharp edges or near hot exhaust, and that it moves freely through full pedal travel.

- Testing after work
- With engine off, operate pedal through full travel and watch throttle movement; ensure no binding and full return.
- Start engine, idle in park/neutral; test gentle revs and quick blips to verify response and that idle returns.
- Road-test at low speed in a safe area to confirm smooth acceleration and full return; check for abnormal noises or hesitation.

- Common problems and fixes
- Sticky/sluggish throttle: inner cable dry or corroded — apply cable lube or replace cable.
- Excessive free play after adjustment: adjuster at its limit or cable stretched — replace cable.
- Throttle hangs open: missing/weak return spring or cable binding — replace spring or cable and check routing.
- Broken/frayed cable: replace cable immediately — fraying will fail catastrophically.

- Final notes (concise)
- If your Hilux has no physical throttle cable (electronic throttle), stop and use a qualified shop — electronic systems require diagnostic equipment and different procedures.
- Use replacement parts matched to your Hilux year/engine; OEM recommended for reliable fit and safety.
- If you are not comfortable removing under-dash clips or engine-bay brackets, seek a mechanic — incorrect installation can cause uncontrolled acceleration or no throttle return.

- Quick checklist before driving
- Cable installed and routed correctly, clips secure
- Locknut tightened on adjuster
- Throttle returns quickly with pedal release
- No frayed cable strands visible
- Test drive confirms normal operation

No extra commentary.
