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.
3. After the engine cools, open the coolant air bleed valve.
There is one bleed valve. It is located on the
thermostat housing.
4. Fill the radiator with the proper DEX - COOL

coolant mixture, up to the base of the filler neck.
See “Engine Coolant” in the Index for more
information about the proper coolant mixture.
If you see a stream of coolant coming from an air
bleed valve, close the valve. Otherwise, close the
valve after the radiator is filled.
