lines on the see-through reservoir when the engine is cool. See
page 200 for additional information.
Radiator and hoses
Make sure the front of the radiator is clean and not blocked with
leaves, dirt or bugs. Check the hoses for cracks, kinks, rot and
loose connections.
Battery electrolyte level

Check the level on the dipstick. The level should be in the
“HOT” or “COLD” range depending on the fluid temperature.
See page 208 for additional information.
Automatic transmission fluid level

selector lever in “P”. The level should be in the “HOT” or
“COOL” range according to the fluid temperature. See page

Be on the alert for changes in performance and sounds, and
visual tip-offs that indicate service is needed. Some important
clues are:

Engine missing, stumbling, or pinging

Appreciable loss of power

Strange engine noises

A fluid leak under the vehicle (However, water dripping from
the air conditioning after use is normal.)

Change in exhaust sound (This may indicate a dangerous
carbon monoxide leak. Drive with the windows open and
have the exhaust system checked immediately.)

Flat-looking tires, excessive tire squeal when cornering,
uneven tire wear

Vehicle pulls to one side when driving straight on a level
road

Strange noises related to suspension movement

Loss of brake effectiveness, spongy feeling brake pedal,
pedal almost touches floor, vehicle pulls to one side when
braking

Engine coolant temperature continually higher than normal
