CAUTION:
{
Heater and radiator hoses, and other engine
parts, can be very hot. Do not touch them.
If you do, you can be burned.
Do not run the engine if there is a leak.
If you run the engine, it could lose all coolant.
That could cause an engine fire, and you
could be burned. Get any leak fixed before
you drive the vehicle.
If there seems to be no leak, with the engine on,
check to see if the electric engine cooling fan is running.
If the engine is overheating, the fan should be running.
If it is not, your vehicle needs service.
Notice: Engine damage from running the engine
without coolant is not covered by the warranty.
How to Add Coolant to the Coolant
Recovery Tank
If you have not found a problem yet, but the coolant level
is not at or above the FULL mark, add a 50/50 mixture of
clean, drinkable water and DEX-COOL
coolant recovery tank. See Engine Coolant on page 5-23
for more information about the proper coolant mixture.
CAUTION:
{
Adding only plain water to your cooling
system can be dangerous. Plain water, or
some other liquid such as alcohol, can boil
before the proper coolant mixture will. Your
vehicle's coolant warning system is set for the
proper coolant mixture. With plain water or the
wrong mixture, your engine could get too hot
but you would not get the overheat warning.
Your engine could catch fire and you or others
could be burned. Use a 50/50 mixture of clean,
drinkable water and a proper coolant.
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.
