If Your Engine Overheats - Jeep 2005 Liberty Owner's Manual

IF YOUR ENGINE OVERHEATS

In any of the following situations, you can reduce the
potential for overheating by taking the appropriate ac-
tion.
• On the highways — Slow down.
• In city traffic — While stopped, put transmission in N
(Neutral), but do not increase engine idle speed.
NOTE: There are steps that you can take to slow down
an impending overheat condition. If your air conditioner
is on, turn it off. The air conditioning system adds heat to
the engine cooling system and turning off the A/C
removes this heat. You can also turn the Temperature
Control to maximum heat, the Mode Control to floor, and
the Fan Control to High. This allows the heater core to act
as a supplement to the radiator and aids in removing heat
from the engine cooling system.
WHAT TO DO IN EMERGENCIES 293
If the pointer rises to the "H" (hot mark) on a vehicle
equipped with a gasoline engine , pull over and stop the
vehicle. Do not turn the engine off. Idle the vehicle with
the air conditioning turned off, until the pointer drops
back into the normal range.
CAUTION!
Driving with a hot cooling system could damage
your vehicle. If the temperature gauge reads "H",
pull over and stop the vehicle. Idle the vehicle with
the air conditioner turned off until the pointer drops
back into the normal range. If the pointer remains on
the "H", and you hear continuous chimes, turn the
engine off immediately, and call for service.
