Care must be taken when jacking up and supporting the vehicle. Be sure to lift and support the vehicle at the proper locations. See VEHICLE LIFT AND SUPPORT LOCATIONS .
PRECOATED PARTS: are bolts, nuts, etc. that are coated with a seal lock adhesive at the factory, see Fig 2:
1. If a precoated part is retightened, loosened or caused to move in any way, it must be recoated with the specified adhesive.
2. When reusing precoated parts, clean off the old adhesive and dry with compressed air. Then apply the specified seal lock adhesive to the bolt, nut or threads.
3. Precoated parts are indicated in the component illustrations.
4. Depending on the seal lock agent applied, there may be a case where it is necessary to leave it for a specified time until it hardens.

GASKETS:
When necessary, use a sealer on gaskets to prevent leaks.
BOLTS, NUTS AND SCREWS:
Carefully observe all specifications for bolt tightening torques. Always use a torque wrench.
FUSES:
When replacing fuses, be sure the new fuse has the correct amperage rating. DO NOT exceed the rating or use one with a lower rating.

2. When disconnecting vacuum hoses, use tags to identify where they should be reconnected to. See Fig 7.
3. After completing a job, double check that the vacuum hoses are properly connected. A 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. Use a step-down adapter for adjustment. Once the hose has been stretched, it may leak air.

Using a torque wrench with an extension tool:
1. When a SST or tool is combined with the torque wrench to extend its entire length, if you tighten until the reading of the torque wrench reaches the specified torque value, the actual torque becomes excessive.
2. Unless otherwise noted, only the specified torque is described. In case of using SST or extension tool, calculate the reading of the torque wrench by the formula.
3. Formula T1=T x L2/(L1 + L2)
