C. Pressure Cap
If the coolant inside the coolant recovery
tank is boiling, do not do anything else until
it cools down. The vehicle should be
parked on a level surface.
When the engine is cold, the coolant level
should be at or above the cold fill line on
the coolant recovery tank. If it is not, there
may be a leak at the pressure cap or in the
radiator hoses, heater hoses, radiator,
water pump, or somewhere else in the
cooling system.If there seems to be no leak, with the
engine on, check to see if the electric
engine cooling fans are running. If the
engine is overheating, the fans should be
running. If the fans are not running, the
vehicle needs service.How to Add Coolant to the Coolant
Recovery Tank
If you have not found a problem yet, but
the coolant level is not at the cold fill line,
add a 50/50 mixture of clean, drinkable
water and DEX-COOL
® engine coolant at
the coolant recovery tank. Refer to “Engine
Coolant” in this section for more informa-
tion.
WARNING
An electric engine cooling fan under
the hood can start up even when the
engine is not running and can injure
you. Keep hands, clothing, and tools
away from any underhood electric
fan.
WARNING
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.
CAUTION
Engine damage from running your
engine without coolant is not covered
by your warranty. Refer to “Over-
heated Engine Protection Operating
Mode” in this section for information
on driving to a safe place in an emer-
gency.
CAUTION
Using coolant other than DEX-COOL
®
may cause premature engine, heater
core, or radiator corrosion. In addi-
tion, the engine coolant could require
changing sooner, at 30000 miles
(50000 km) or 24 months, whichever
occurs first. Any repairs would not be
covered by your warranty. Always
use DEX-COOL
® (silicate-free) cool-
ant in your vehicle.
WARNING
Adding only plain water to your cool-
ing 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 DEX-COOL
® coolant.
CAUTION
In cold weather, water can freeze and
crack the engine, radiator, heater
core and other parts. Use the recom-
mended coolant and the proper cool-
ant mixture.
