Checking Coolant
See “Engine Compartment Overview” in the Index
for information on location.
The vehicle must be on a level surface. When your engine
is cold, check the dipstick on the cap of the coolant
recovery tank. The coolant level should be at COLD,
or a little higher. When your engine is warm, the level
on the dipstick should be up to HOT, or a little higher.
Adding Coolant to the Recovery Tank
If you need more coolant, add the proper DEX - COOL
R
coolant mixture at the coolant recovery tank, but only
when your engine is cool. If the tank is very low or
empty, also add coolant to the radiator. See “Engine
Overheating” in the Index for information.
CAUTION:
Turning the radiator 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 pressure cap
-- even a little -- when the engine
and radiator are hot.
Add coolant mixture at the recovery tank, but be careful
not to spill it.
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.
Occasionally check the coolant level in the radiator.
For information on how to add coolant to the radiator,
see “Cooling System” in the Index.
