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.
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 3-28.
Adding Coolant
If you need more coolant, add the proper DEX-COOL
®
coolant mixture
at the surge tank, but only when the
engine is cool. If the surge tank is empty, a special fill
procedure is necessary. See
Engine Overheating
on page 5-24 for instructions on “How to Add Coolant to
the Coolant Surge Tank.”
{
CAUTION:
You can be burned if you spill coolant on hot
engine parts. Coolant contains ethylene glycol,
and it will burn if the engine parts are hot
enough. Don’t spill coolant on a hot engine.
When replacing the pressure cap, make sure it is
hand-tight.
Coolant Surge Tank Pressure Cap
Notice: Your pressure cap is a pressure-type
cap and must be tightly installed to prevent coolant
loss and possible engine damage from overheating.
See “Capacities and Specifications” for more
information.
