Checking Coolant
The engine coolant
recovery tank is located in
the engine compartment
on the passenger's side of
the vehicle, near the
windshield. See Engine
Compartment Overview on
page 5-74 for more
information on location.
Adding 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 up to the FULL HOT mark
or a little higher.
If you need more coolant, add the proper DEX-COOL@
coolant mixture at the coolant recovery tank, but be
careful not to spill it.
