Notice: In cold weather, water can freeze and crack
the engine, radiator, heater core and other parts.
Use the recommended coolant and the proper
coolant mixture.
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.
1. You can remove the coolant surge tank pressure cap
when the cooling system, including the coolant surge
tank pressure cap and upper radiator hose, is no
longer hot. Turn the pressure cap slowly
counterclockwise (left) about one-quarter of a turn.
If you hear a hiss, wait for that to stop. This will
allow any pressure still left to be vented out
the discharge hose.
2. Then keep turning the pressure cap slowly, and
remove it.
3. Fill the coolant surge tank with the proper
®
DEX-COOL coolant mixture, to the COLD line.
