Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Repair Instruction: Precaution
- BASIC REPAIR HINT
- HINTS ON OPERATIONS
- JACKING UP AND SUPPORTING VEHICLE
- Care must be taken when jacking up and supporting the vehicle. Be sure to lift and support the vehicle at the proper locations.
- PRECOATED PARTS
- Precoated parts are bolts and nuts that are coated with a seal lock adhesive at the factory.
- If a precoated part is retightened, loosened or moved in any way, it must be recoated with the specified adhesive.
- When reusing a precoated part, clean off the old adhesive and dry the part with compressed air. Then apply new seal lock adhesive appropriate to that part.
- Some seal lock agents harden slowly. You may have to wait for the seal lock adhesive to harden.
- GASKET
- When necessary, use a sealer on gaskets to prevent leaks.
- BOLTS, NUTS AND SCREWS
- Carefully follow all the specifications for tightening torques. Always use a torque wrench.
- FUSES
- When inspecting a fuse, check that the wire of the fuse is not broken.
- When replacing fuses, be sure that the new fuse has the correct amperage rating. Do not exceed the rating or use one with a lower rating.FUSE SYMBOL REFERENCE

- clips
- The removal and installation methods of typical clips used for vehicle body parts are shown in Fig 4.
HINT:
If clips are damaged during a procedure, always replace the damaged clip with a new clip.
- The removal and installation methods of typical clips used for vehicle body parts are shown in Fig 4.
- CLAWS
- The removal and installation methods of typical claws used for vehicle body parts are shown in Fig 5.
HINT:
If claws are damaged during a procedure, always replace the damaged claws with new caps or covers.
- The removal and installation methods of typical claws used for vehicle body parts are shown in Fig 5.
- REMOVAL AND INSTALLATION OF VACUUM HOSES
- To disconnect a vacuum hose, pull and twist from the end of the hose. Do not pull from the middle of the hose as this may cause damage.
- When disconnecting vacuum hoses, use tags to identify where they should be reconnected.
- After completing any hose related repairs, double check that the vacuum hoses are properly connected. The label under the hood shows the proper layout.
- When using a vacuum gauge, never force the hose onto a connector that is too large. If a hose has been stretched, it may leak air. Use a step-down adapter if necessary.
- TORQUE WHEN USING TORQUE WRENCH WITH EXTENSION TOOL
- Use the formula below to calculate special torque values for situations where SST or an extension tool is combined with a torque wrench.
Formula:
T' = L2 / (L1 + L2) * T
FORMULA TABLET' Reading of torque wrench {N*m (kgf*cm, ft.*lbf)} T Torque {N*m (kgf*cm, ft.*lbf)} L1 Length of SST or extension tool {cm (in.)} L2 Length of torque wrench {cm (in.)} NOTE: If an extension tool or SST is combined with a torque wrench and the wrench is used to tighten to a torque specification in this article, the actual torque will be excessive and parts will be damaged.

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
