POWER STEERING PUMP - INITIAL OPERATION
WARNING: THE FLUID LEVEL SHOULD BE CHECKED WITH ENGINE OFF TO PREVENT INJURYFROMMOV-
ING COMPONENTS.
CAUTION: MOPAR
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.
Wipe filler cap clean, then check the fluid level. The dipstick should indicateCOLDwhen the fluid is at normal
temperature.
1. Turn steering wheel all the way to the left.
2. Fill reservoir up to FULL HOT level and crank engine until it just starts.(DO NOT TURN STEERING WHEEL).
Then turn vehicle off. And recheck fluid level, to Full COLD.
3. Crank engine again until it just starts, (DO NOT MOVE STEERING WHEEL). and turn vehicle off. Recheck fluid
leveltoFullCOLD.
4. Turn engine on again, (DO NOT MOVE STEERING WHEEL) and let the vehicle idle for 5 minutes. If possible
apply a 20 in-Hg vacuum to the reservoir, while engine is idling.
5. Turn engine off and recheck fluid level, to FULL COLD.
6.If the Steering gear is replacedensure reservoir is at FULL HOT level, start engine and turn wheel to left. Stop
Engine and recheck fluid level to FULL HOT. Start engine and turn wheel to the right. Stop engine and check
fluid level is at FULL COLD.
7. Fill the pump fluid reservoir to the proper level and let the fluid settlefor at least two (2) minutes.
8. Start the engine. With the engine idling maintain the fluid level.
9. Raise the front wheels off the ground.
10. Slowly turn the steering wheel lock-to-lock 20 times with the engine off while checking the fluid level.
NOTE: For vehicles with long return lines or oil coolers turn wheel 40 times.
11. Lower the front wheels and let the engine idle for two minutes.
12. Turn the steering wheel in both direction and verify power assist and quiet operation of the pump.
If the fluid is extremely foamy or milky looking, allow the vehicle to standa few minutes and repeat the procedure.

REMOVAL
GAS ENGINE
1. Drain and siphon the power steering fluid from the
reservoir.
2. Remove the serpentine belt.
CAUTION: Do not remove the fitting on the pump
that the high pressure hose screws into. The fit-
ting may come loose unless it is backed up using
another wrench. If the fitting does come loose, it
must be retightened before continuing. (57 - 67
Nm, 40 - 50 lb.ft.). If this fitting comes out of the
pump body, the internal spring and valve parts will
fall out of the pump and they cannot be reinstalled
properly. If this occurs the pump needs to be
replaced with a new pump.
3. Disconnect the return hose (3).
4. Disconnect the pressure hose (4).
5. Access to remove the three bolts securing the pump to the cylinder head can be gained thru the pulley holes (1).

FLUID
DESCRIPTION
NOTE: It is normal that some pressure will build up inside the reservoir, especially, with a warm vehicle. A
slight popping noise upon removal ofthe cap is normal. The fluid level should read between the ADD and
the FULL COLD marks. When the fluid is hotit should read between ADD and FULLHOT marks. Only add
fluid when the vehicle is cold.
The recommended fluid for the power steering system is Mopar
AT F + 4 .
Mopar
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 andis 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: FLUID LEVEL SHOULD BE CHECKED WITH THE ENGINE OFF TO PREVENT PERSONAL INJURY
FROM MOVING PARTS.
CAUTION: MOPAR
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.
The power steering fluid level can be viewed on the dipstick attached to thefiller 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 thehighest end of the HOT range. Only add
fluid when the vehicle is cold.
Use only Mopar
AT F + 4 .Do not overfill the power steering system.
