How to Add Coolant to the Cooling
System
Notice: Your engine has a specific cooling
system drain and fill procedure. Failure
to follow this procedure could cause your
engine to overheat and be severely damaged.
If your engine’s cooling system needs to
be drained and re-filled, please see your dealer.
1. Remove the
pressure cap
when the cooling
system, including
the pressure
cap and upper
radiator hose is
no longer hot.
Turn the pressure cap slowly counterclockwise.
If you hear a hiss, wait for that to stop. A hiss
means that there is still some pressure left.
2. Then keep turning the pressure cap and
remove 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. Do not spill
coolant on a hot engine.
3. Fill the cooling system with the proper
DEX-COOL
®
coolant mixture, up to the base
of the filler neck. See Engine Coolant on
page 320 for more information about
the proper coolant mixture.
4. Rinse or wipe any spilled coolant from the
engine and the compartment.
5. Then fill the coolant recovery tank to the cold
fill line.
6. Install the coolant recovery tank cap and the
pressure cap. After a day or two of driving,
when the engine is cold, check the coolant
level in the recovery tank. If it is low, refill it to
the cold fill line.
If the coolant in the recovery tank is constantly
low, you should have a dealership service
department inspect the vehicle for leaks.
