freeze and boil protection,
corrosion inhibitor level and
maintains proper engine
operating temperature.
Inspect hoses and replace if
they are cracked, swollen or
deteriorated. Tighten screw-type
hose clamps. Clean the outside of
the radiator and air conditioning
condenser. Wash the pressure cap
and neck.
To help ensure proper operation,
we recommend a pressure test of
both the cooling system and the
pressure cap.

completion
of vehicle useful life. General
Motors, however, urges that all recommended
maintenance services be performed at the
indicated intervals and the maintenance be
recorded in “Section

WHAT TO DO
Lubricate the key lock cylinders with the lubricant specified in Section D.
Lubricate all body door hinges. Also lubricate all hinges and latches, including those for the hood,
rear compartment, glove box door, console door and any folding seat hardware. Section
D tells
you what to use.
1. Before you start, be sure you have enough room around the vehicle.
2. Firmly apply both the parking brake (see “Parking Brake” in the Index if necessary) and the
regular brake.
....
NOTE: Do not use the accelerator pedal, and be ready to turn off the engine immediately if it
starts.
3. On automatic transmission vehicles, try to start the engine in each gear. The starter should
work only in
“P” (Park) or “N” (Neutral). If the starter works in any other position, your
vehicle heeds service.
On manual transmission vehicles, put the shift lever in “N” (Neutral), push the clutch down
halfway and try to start the engine. The starter should work only when the clutch is pushed
down all the way to the floor. If the starter works when the clutch isn’t pushed all the way
down, your vehicle needs service.
