Adding Coolant
If you need more coolant, add the proper
DEX-COOL
®
coolant mixture at the coolant surge
tank, but only when the engine is cool. If the
coolant surge tank is empty, a special fill
procedure is necessary. See Engine Overheating
on page 290 for instructions on “How to Add
Coolant to the Coolant Surge Tank.”
{CAUTION:
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. Do not spill
coolant on a hot engine.
When replacing the pressure cap, make sure it is
hand-tight and fully seated.
Coolant Surge Tank Pressure Cap
Notice: If the pressure cap is not tightly
installed, coolant loss and possible engine
damage may occur. Be sure the cap is properly
and tightly secured.
Engine Overheating
You will find a coolant temperature gage on your
vehicle’s instrument panel cluster. See Engine
Coolant Temperature Gage on page 167.
