Checking Coolant (3.8L V6 Engine)
The engine coolant recovery tank is located in the
engine compartment on the passenger's side of
the vehicle. See Engine Compartment Overview on
page 5-12 for more information on location.
The vehicle must be on a level surface. When your
engine is cold, the coolant level should be at FULL
COLD or a little higher. When your engine is warm, the
level should raise.
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.
5-26
This symbol is located on
the cap of the engine
coolant recovery tank.
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 Index. When replacing the pressure cap, make sure
to turn cap until it clicks.
