Checking Coolant
The engine coolant surge
tank is located toward the
rear of the engine
compartment on the
passenger’s side of
the vehicle.
For more information on location, see Engine
Compartment Overview on page 5-12.
{
CAUTION:
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, located on the side of the surge tank
that faces the engine.
