Checking Coolant
The vehicle must be on a level surface. When
your engine is cold, the coolant level should be
at the full cold mark, or a little higher. When your
engine is warm, the level should be above the
full cold 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.
The coolant recovery
tank is located on the
driver's side of the
vehicle, above
the engine air
cleaner/filter. See
Engine Compartment
Overview on page 364
for more information
on location.
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.
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.
Occasionally check the coolant level in the
radiator. For information on how to add coolant to
the radiator, see Cooling System on page 381.
