Checking Coolant
The engine coolant 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 or slightly higher.
If the low coolant light
comes on and stays on, it
means you’re low on
engine coolant.
See Low Coolant Warning Light on page 3-29 for more
information.
