Checking Coolant

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 near the bottom of the surge tank and has an
arrow pointing down at it.

The coolant recovery tank
is located in the engine
compartment toward
the rear of the engine on
the passenger's side of
the vehicle. See Engine
Compartment Overview
on page 5-12 for more
information on location.
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 radiator. See Engine Overheating
on page 5-27.
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.
