FLUID
DESCRIPTION
The recommended fluid for the power steering system is Mopar
T
ATF +4.
Mopar
T
ATF+4, when new is red in color. The ATF+4 is dyed red so it can be identified from other fluids used in the
vehicle such as engine oil or antifreeze. The red color is not permanent and is not an indicator of fluid condition, As
the vehicle is driven, the ATF+4 will begin to look darker in color and may eventually become brown. THIS IS NOR-
MAL. ATF+4 also has a unique odor that may change with age. Consequently, odor and color cannot be used to
indicate the fluid condition or the need for a fluid change.
STANDARD PROCEDURE - POWER STEERING FLUID LEVEL CHECKING
WARNING: The fluid level should be checked with engine off to prevent injury from moving components.
CAUTION: MOPAR
T
ATF+4 is to be used in the power steering system. No other power steering or auto-
matic transmission fluid is to be used in the system. Damage may result to the power steering pump and
system if any other fluid is used, and do not overfill.
NOTE: Power steering reservoir does not contain a dipstick. Fluid level indicators are molded into the side
of the reservoir WITH REMOTE RESERVOIR.
The power steering fluid level can be viewed on the dipstick attached to the filler cap. There are two ranges listed
on the dipstick, COLD and HOT. Before opening power steering system, wipe the reservoir filler cap free of dirt and
debris. Remove the cap and check the fluid level on its dipstick. When the fluid is at normal ambient temperature,
approximately 21°C to 27°C (70°F to 80°F), the fluid level should read between the minimum and maximum area of
the cold range. When the fluid is hot, fluid level is allowed to read up to the highest end of the HOT range. Only add
fluid when the vehicle is cold.
Use only Mopar
T
ATF+4 . Do not overfill the power steering system.

FLUID COOLER
DESCRIPTION
The power steering fluid cooler (1) is located at the
front of the vehicle. It is mounted to the radiator lower
support just forward of the air-conditioning condenser
and just rearward of the front fascia. The cooler is
positioned so it is in the air flow through the front fas-
cia of the vehicle. The cooler is serviced as an assem-
bly with the return hose.
OPERATION
The purpose of the power steering fluid cooler (2) is to
keep the temperature of the power steering system
fluid from rising to a level that would affect the perfor-
mance of the power steering system.
The cooler used on this vehicle is referred to as a flu-
id-to-air type cooler. This means that the air flow
across the fin/tubes of the cooler is used to extract the
heat from the cooler which it has absorbed from the
power steering fluid flowing through it. The cooler is
placed in series with the power steering fluid return
line (1), between the steering gear and the power
steering fluid reservoir. This lowers the temperature of
the power steering fluid prior to it entering the power
steering fluid reservoir where it is resupplied to the
power steering pump.
REMOVAL
1. Remove the return line at the gear.
2. Remove the return line at the reservoir.
3. Remove the grille (Refer to 23 - BODY/EXTERIOR/
GRILLE - REMOVAL).
4. Remove the two cooler mounting bolts (2).
5. Remove the cooler (1) and return hose assembly
from the vehicle.
