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 dealer/retailer service
department inspect the vehicle for leaks.
