The engine coolant
surge tank is located
toward the rear of
the engine compartment
on the passenger's
side of the vehicle.
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.
