NOTICE:
Y o u radiator cap is a 15 psi (105
kPa) pressure-type cap and must be
tightly installed to prevent coolant
loss and possible engine damage
from overheating. Be sure the arrows
on the cap line up with the overflow
tube on the radiator filler neck.
When you replace your radiator
pressure cap, a GM cap is recommended.
Thermostat
Engine coolant temperature is
controlled by a thermostat in the engine
coolant system. The thermostat stops
the flow of coolant through the radiator
until the coolant reaches a preset
temperature.
When you replace your thermostat, an
AC@ thermostat is recommended.

with a clean rag. Replace the cap and
completely tighten it. Then remove the
cap again and look at the fluid level on
the dipstick.
When the engine compartment is hot,
the level should be near the H mark.
When the engine compartment is cool,
the level should be near the
C
mark.
