Checking Coolant
The surge tank is located on the driver's
side of the engine compartment. See Engine
Compartment Overview on page 314 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 COLD FILL line. When your engine is
warm, the level should be at the COLD FILL line or
a little higher.
