GENERAL REPAIR INSTRUCTIONS

Use fender, seat and floor covers to keep the vehicle

clean and prevent damage.

During disassembly, keep parts in order to facilitate re-

assembly.

Observe the following:

(a)

Before performing electrical work, disconnect the

cable from the battery terminal.

(b)

If it is necessary to disconnect the battery for in-

spection or repair, always disconnect the cable from

the negative (—) terminal which is grounded to the

vehicle body.

(c)

To prevent damage to the battery terminal post,

loosen the terminal nut and raise the cable straight

up without twisting or prying it.

(d)

Clean the battery terminal posts and cable terminal

with a shop rag. Do not scrape them with a file or

such.

(e)

Install the cable terminal to the battery post with the

nut loose and tighten the nut after installation. Do

not use a hammer or such to tap the terminal onto

the post.

(f)

Be sure the cover for the positive (+) terminal is

properly in place.

Check all hose and wiring connectors to make sure they

are securely and correctly connected.

Non-reusable Parts

(a)

Always replace cotter pins, gaskets, 0-ring and oil

seals, etc. with new ones.

(b)

Non-reusable parts are indicated in the component

illustrations by the "s" symbol.

Precoated Parts

Precoated parts are bolts, nuts, etc. that are coated with

a seal lock adheasive at the factory.

(a) If a precoated part is tightened, loosened or caused

to move in any way, if must be recoated with the

specified adhesive.

(b) Recoating of Precoated Parts

(1)

Clean off the old adhesive from the bolts, nut or

installation part threads.

(2)

Dry with compressed air.

(3)

Apply the specified seal lock adhesive to the

bolt or nut threads.

lustrations by the "*" symbol.

When necessary, use a sealer on gaskets to prevent leaks.

Carefully observe all specifications for bolt tightening

torques. Always use a torque wrench.

Use of special service tools (SST) and special service

materials (SSM) may be required depending on the na-

ture of the repair. Be sure to use SST and SSM where

specified and follow the proper work procedure. A list of

SST and SSM can be found at the back of this manual.

0. When replacing fuses, be sure the new fuse is the correct

amperage rating. DO NOT exceed the rating or use one

of a lower rating.

11. Care must be taken when jacking up and supporting the

vehicle. Be sure to lift and support the vehicle at the

proper locations.

(a)

If the vehicle is to be jacked up only at the front or

rear end, be sure to block the wheels in order to

ensure safety.

(b)

After the vehicle is jacked up, be sure to support it

on stands. It is extremely dangerous to do any work

on the vehicle raised on one jack alone, even for a

small job that can be finished quickly.

2. Observe the following precautions to avoid damage to

parts:

(a)

To disconnect vacuum hoses, pull on the end, not

the middle of the hose.

(b)

To pull apart electrical connectors, pull on the con-

nector itself, not the wires.

(c)

Be careful not to drop electrical components, such

as sensors or relays. If they are dropped on a hard

floor, they should be replaced and not reused.

(d)

When steam cleaning an engine, protect the distrib-

utor, coil, air filter, and VCV from water.

(e)

Never use an impact wrench to remove or install

temperature switches or temperature sensors.

(f)

When checking continuity at the wire connector,

insert the tester probe carefully to prevent terminals

from bending.

(g)

When using a vacuum gauge, never force the hose

onto a connector that is too large. Use a step-down

adapter instead. Once the hose has been stretched,

it may leak.

3. Tag hoses before disconnecting them:

(a)

When disconnecting vacuum hoses, use tags to

identify how they should be reconnected.

(b)

After completing a job, double check that the vac-

uum hoses are properly connected. A label under

the hood shows the proper layout.
