Checking Intercooler System Coolant
(4.4L V8 STS-V Engine Only)
The vehicle must be on a level surface when checking
the coolant level.
See Engine Compartment Overview on page 5-12 for
the location of the intercooler system pressure cap.
Turn off the engine. When the engine is cold, the coolant
level should be visible in the intercooler fill neck.
How to Add Coolant to the 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.
Notice: This vehicle has a specific coolant fill
procedure. Failure to follow this procedure could
cause the engine to overheat and be severely
damaged.
