Downloaded from www.Manualslib.com manuals search engine Adding Coolant
If you need more coolant, add the proper DEX-COOL@
coolant mixture at the surge tank, but only when the
engine
is cool.
r-
You can be burned if you spill coolant on hot
engine parts. Coolant contains ethylene glycol, and it will burn if the engine parts are hot
enough. Don’t spill coolant on
a hot engine.
Surge Tank Pressure Cap
I NOTICE:
The surge tank 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.
If the surge tank pressure cap needs to be replaced, a
GM cap is recommended.
Thermostat When replacing the pressure cap, make sure it is tight.
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.
If your thermostat needs to be replaced, a GM
thermostat is recommended.
