4 Preparation of tools and measuring gauge Before starting operation, prepare a tool stand, SST, gauge, oil and parts for replacement. 5 Removal and installation, disassembly and assembly operations - Diagnose with a thorough understanding of proper procedures and of the reported problem.
- Before removing the parts, check the general condition of the assembly and for deformation and damage.
- When the assembly is complicated, take notes. For example, note the total number of electrical connections, bolts, or hoses removed. Add matchmarks to ensure reassembly of components in the original positions. Temporarily mark hoses and their fittings if needed.
- Clean and wash the removed parts if necessary and assemble them after a thorough check.
6 Removed parts - Place the removed parts in a separate box to avoid mixing them up with the new parts or contaminating the new parts.
- For non-reusable parts such as gaskets, O-rings, and self-locking nuts, replace them with new ones as instructed in this information.

- PRECOATED PARTS
- Precoated parts are bolts and nuts that are coated with a seal lock adhesive at the factory.

- 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.
- GASKETS
- 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.
- If the wire of a fuse is broken, confirm that there are no shorts in its circuit.
- When a fuse is replaced, a fuse with the same amperage rating must be used.

- 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.
