Surge Tank for Gasoline Engines

If the vehicle has a diesel engine, see “Cooling System”
in the DURAMAX

Diesel Supplement for the proper

coolant fill procedure.

WARNING:

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.

WARNING:

An electric engine cooling fan under the hood can
start up even when the engine is not running and
can cause injury. Keep hands, clothing, and tools
away from any underhood electric fan.
