CLEANLINESS AND CARE
An automobile engine is a combination of many machined,
honed, polished and lapped surfaces with tolerances that
are measured in ten–thousandths of an inch. When any in-
ternal engine parts are serviced, care and cleanliness are
important. A liberal coating of engine oil should be applied
to friction areas during assembly, to protect and lubricate
the surfaces on initial operation. Proper cleaning and
protection of machined surfaces and friction areas is part
of the repair procedure. 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 mating 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 elec-
trical 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. Disconnecting
this cable will help prevent personal injury and dam-
age to the vehicle. The ignition must also be in LOCK
unless otherwise noted.
Notice : Any time the air cleaner is removed, the intake
opening should be covered. This will protect against the
accidental entrance of foreign material, which could follow
the intake passage into the cylinder and cause extensive
damage when the engine is started.
