Checking Coolant
See Engine Compartment Overview on page 308
for more information on the location of the
coolant recovery tank.
The vehicle must be on a level surface when
checking the coolant level.
When the engine is cold, the coolant level
should be at the cold fill line or a little higher.
The cold fill line is marked with the same symbol
as the coolant recovery tank cap.

The coolant recovery
tank cap has this
symbol on it.
Adding Coolant
If more coolant is needed, add the proper
®
DEX-COOL coolant mixture at the coolant
recovery tank, but be careful not to spill it.
If the coolant recovery tank is completely empty,
add coolant to the cooling system through the
coolant fill neck on the engine. See Engine
Overheating on page 323.
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.
