Basic Repair Hints
PRECAUTIONBASIC REPAIR HINT
a. HINTS ON OPERATIONS
b. JACKING UP AND SUPPORTING VEHICLE
1. Care must be taken when jacking up and supporting the vehicle. Be sure to lift and support the vehicle at the proper locations.
c. PRECOATED PARTS
1. Precoated parts are bolts and nuts that are coated with seal lock adhesive at the factory.
2. If a precoated part is retightened, loosened or moved in any way, it must be recoated with the specified adhesive.
3. 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.
4. Some seal lock adhesive harden slowly. You may have to wait for the seal lock adhesive to harden.
d. GASKETS
1. When necessary, use a sealer on gaskets to prevent leaks.
e. BOLTS, NUTS AND SCREWS
1. Carefully observe all the specifications for tightening torques. Always use a torque wrench.
f. FUSES
1. When inspecting a fuse, check that the wire of the fuse is not broken.
2. When replacing a fuse, be sure that the new fuse has the correct amperage rating. Do not use one with higher or lower rating.
g. CLIPS
1. The removal and installation methods of typical clips used for vehicle body parts are shown in the table.
HINT: If clips are damaged during a procedure, always replace the damaged clip with a new clip.
h. REMOVAL AND INSTALLATION OF VACUUM HOSES
1. To disconnect a vacuum hose, pull and twist it from its end. Do not pull from the middle of the hose as this may cause damage.
2. When disconnecting vacuum hoses, use tags to identify where they should be reconnected.
3. After completing any hose related repairs, double check that the vacuum hoses are properly connected. The label under the hood shows the proper layout.
4. 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.
i. TORQUE WHEN USING TORQUE WRENCH WITH EXTENSION TOOL
1. Use the formula below to calculate special torque values for situations where SST or an extension tool is combined with the torque wrench.
Formula: T' = T x L2 / (L1 + L2)
NOTE: If an extension tool or SST is combined with a torque wrench and the wrench is used to tighten to a torque specification, the actual torque will be excessive and parts will be damaged.
