Checking Coolant
The coolant surge tank is located in the engine
compartment behind the passenger's side headlamp.
See Engine Compartment Overview on page 5-12
for more intormation on locatlon.
Turning the surge tank pressure cap when the
engine and radiator are hot can allow steam
and scalding liquids to blow out and burn
you badly. Never turn the surge tank pressure
cap
-
even a little
-
when the engine and
radiator are hot.
The vehicle must be on a level surface. When your
engine is cold, the coolant level should be at the FULL
COLD mark. The FULL COLD mark is on the front
of the coolant surge tank. Don't overfill the surge tank.
Too much coolant can result in an overflow when
the fluid is hot.
