CAUTION!
Failure to use the proper antifreeze could cause
radiator plugging and engine overheating. Do not
mix antifreeze brands or types. Do not use plain
water alone or alcohol base antifreeze products. Do
not use additional rust inhibitors or antirust prod-
ucts, as they may not be compatible with the radiator
coolant and may plug the radiator.
Adding Coolant
When adding coolant, a minimum solution of 50% eth-
ylene glycol antifreeze coolant and water should be used.
Use higher concentrations (not to exceed 70%) if tempera-
tures below -34°F (-37°C) are anticipated.
Use only high purity water, such as distilled or deionized
water when mixing the water/antifreeze solution. The
use of lower quality water will reduce the amount of
corrosion protection in the engine cooling system.
NOTE: Mixing coolant types other than Mopar prod-
ucts will decrease the life of the engine coolant and will
require more frequent coolant changes.
MAINTAINING YOUR VEHICLE 195
Please note that it is the owner's responsibility to main-
tain the proper level of protection against freezing,
according to the temperatures occurring in the area
where the vehicle is operated.
Cooling System Pressure Cap
The cap must be fully tightened to prevent loss of
coolant, and to insure that coolant will return to the
radiator from the coolant reserve tank.
The cap should be inspected and cleaned if there is any
accumulation of foreign material on the sealing surfaces.
WARNING!
The warning words "DO NOT OPEN WHEN HOT"
near the cooling system reservoir cap are a safety
precaution. Never add coolant when the engine is
overheated. Do not loosen or remove the cap to cool
an overheated engine. Heat causes pressure to build
up in the cooling system. To prevent scalding or
injury, do not remove the pressure cap while the
system is hot or under pressure.
