1A – 2 GENERAL ENGINE INFORMATION

DESCRIPTION AND SYSTEMOPERATION

CLEANLINESS AND CARE

An automobile engine is a combination of many ma-
chined, honed, polished and lapped surfaces with toler-
ances that are measured in the ten–thousandths of an
inch. When any internal engine parts are serviced, care
and cleanliness are important. A liberal coating of en-
gine oil should be applied to friction areas during assem-
bly, to protect and lubricate the surfaces on initial
operation. Proper cleaning and protection of machined
surfaces and friction areas is part of the repair proce-
dure. This is considered standard shop practice even if
not specifically stated.

Whenever valve train components are removed for ser-
vice, they should be kept in order. They should be
installed in the same locations, and with the same mat-
ing surfaces, as when they were removed. Battery
cables should be disconnected before any major work is
performed on the engine. Failure to disconnect cables

may result in damage to wire harness or other electrical
parts.

ON-ENGINE SERVICE

Caution: Disconnect the negative battery cable be-
fore removing or installing any electrical unit, or
when a tool or equipment could easily come in con-
tact with exposed electrical terminals. Disconnect-
ing this cable will help prevent personal injury and
damage to the vehicle. The ignition must also be in
B unless otherwise noted.

Notice: Any time the air cleaner is removed, the intake
opening should be covered. This will protect against ac-
cidental entrance of foreign material, which could follow
the intake passage into the cylinder and cause exten-
sive damage when the engine is started.
