NOTICE:

When adding coolant, it is important that you use

only DEX

-COOL (silicate-free) coolant.

If coolant other than DEX-COOL is added to the

system, premature engine, heater core or

radiator corrosion may result. In addition, the

engine coolant will require change sooner

-- at

30,000 miles (50 000 km) or 24 months,

whichever occurs first. Damage caused by the use

of coolant other than DEX

-COOL is not

covered by your new vehicle warranty.

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, both fans should be running. If

they aren’t, your vehicle needs service.

How to Add Coolant to the Coolant

Surge Tank

If you haven’t found a problem yet, but the coolant level

isn’t at or above the FULL COLD mark, add a 50/50

mixture of clean, drinkable water and DEX-COOL

coolant at the coolant surge tank, but be sure the cooling

system, including the coolant surge tank pressure cap, is

cool before you do it. See “Engine Coolant” in the Index

for more information.

CAUTION:

Steam and scalding liquids from a hot cooling

system can blow out and burn you badly. They

are under pressure, and if you turn the coolant

surge tank pressure cap

-- even a little -- they

can come out at high speed.
