Radiator Pressure Cap
Notice: The radiator cap on your vehicle is a
pressure-type cap and must be tightly installed to
prevent coolant loss and possible engine damage
from overheating. Be sure the arrows on the cap line
up with the overflow tube on the radiator filler neck.
The radiator pressure cap is located near the front of the
engine compartment on the passenger’s side of the
vehicle. See Engine Compartment Overview on
page 5-12 for more information on location.
Engine Overheating
The coolant temperature gage and the hot engine
warning light on the instrument panel can indicate an
overheated engine condition. See Engine Coolant
Temperature Gage on page 3-34 and Engine Coolant
Temperature Warning Light on page 3-34.
Overheated Engine Protection
Operating Mode
The emergency operating mode allows the vehicle to be
driven to a safe place in an emergency situation. If an
overheated engine condition exists, this mode alternates
firing groups of cylinders, to help prevent engine
damage. In this mode, there will be a significant loss in
power and engine performance. The engine coolant
temperature gage will move to the red area and
the engine coolant temperature warning light will come
on, indicating that an overheated engine condition
exists. Driving extended miles (km) and/or towing a
trailer in the overheated engine protection operating
mode should be avoided.
Notice: After driving in the overheated engine
protection operating mode, to avoid engine damage,
allow the engine to cool before attempting any
repair. The engine oil will be severely degraded.
Repair the cause of coolant loss, change the oil and
reset the oil life system. See Engine Oil on
page 5-16.
