Checking Coolant for Gasoline Engines
If your vehicle has a diesel engine, see “Checking
Coolant” under “Van Models” in the DURAMAX
®
Diesel Supplement for information on checking
your vehicle’s coolant.
The coolant recovery
tank is located near the
center of the engine
compartment. See
Engine Compartment
Overview on page 298
for more information
on location.
The vehicle must be on a level surface. When
your engine is cold, the coolant level should be
at the COLD FILL mark, or a little higher.
Adding Coolant
If you need more coolant, add the proper
DEX-COOL
®
coolant mixture at the coolant
recovery tank, but be careful not to spill it.
{CAUTION:
Turning the radiator pressure cap when
the engine and radiator are hot can allow
steam and scalding liquids to blow out
and burn you badly. With the coolant
recovery tank, you will almost never have
to add coolant at the radiator. Never
turn the radiator pressure cap — even
a little — when the engine and radiator
are hot.
