3. Fill the coolant surge tank with the proper mixture,
to the COLD FILL line. Wait about five minutes,
then check to see if the level is below the COLD
FILL line. If the level is below the line, add additional
coolant to bring the level up to the line. Repeat
this procedure until the level remains constant at the
COLD FILL line for at least five minutes.
4. With the coolant surge tank pressure cap off, start
the engine and let it run until you can feel the upper
radiator hose getting hot. Watch out for the
engine cooling fan.
By this time, the coolant level inside the coolant
surge tank may be lower. If the level is lower than
the COLD FILL line, add more of the proper mixture
to the coolant surge tank until the level reaches
the COLD FILL line.
5. Then replace the pressure cap. Be sure the
pressure cap is hand-tight and fully seated.
See your dealer/retailer, if necessary.
Engine Coolant
The cooling system in your vehicle is filled with
DEX-COOL
®
engine coolant. This coolant is designed
to remain in your vehicle for five years or 150,000 miles
(240 000 km), whichever occurs first, if you add only
DEX-COOL
®
extended life coolant.
The following explains your cooling system and how to
add coolant when it is low. If you have a problem
with engine overheating, see Engine Overheating on
page 6-27.
A 50/50 mixture of clean, drinkable water and
DEX-COOL
®
coolant will:
• Give freezing protection down to −34°F (−37°C).
• Give boiling protection up to 265°F (129°C).
• Protect against rust and corrosion.
• Help keep the proper engine temperature.
• Let the warning lights and gages work as they
should.
