GENERAL INFORMATION
CLEANLINESS AND CARE
An automobile engine is a combination of many
machined, honed, polished and lapped surfaces with
tolerances that are measured in the ten-thousanths
of an inch. When any internal engine parts are
serviced, care and cleanliness are important. A liberal
coating of enigne 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 fo the
repair procedure. This is considered standard shop
practice even if not specifically stated.
Whenever valve train components are removed for
service, 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 electrical parts.
ON-ENGINE SERVICE
Caution: Disconnect the negative battery cable
before removing or installing any electrical unit,
or when a tool or equipment could easily come in
contact with exposed electrical terminals.
Disconnecting this cable will help prevent
personal injury and damage 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
accidental entrance of foreign material, which could
follow the intake passage into the cylinder and cause
extensive damage when the engine is started.
