Checking Coolant
The surge tank is located
in the engine compartment
on the passenger’s side
of the vehicle. See Engine
Compartment Overview
on page 5-12 for more
information on location.
{
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.
