TIP
G
The coolant level must be checked
on a cold engine since the level
varies with engine temperature.
G Make sure that the vehicle is posi-
tioned straight up when checking
the coolant level. A slight tilt to the
side can result in a false reading.
TIP
The coolant should be at the bottom of
the radiator filler neck. The level will
change with variation of engine temper-
ature.
1. Correct coolant level
3. If the coolant is below this level,
add coolant, and then install the
radiator cap.
