Dodge Ram Truck 1500-2500-3500. Manual — part 1508

CAUTION: Do not run a vehicle with foamy fluid for an extended period. This may cause pump damage.

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 - 67Nm,
40 - 50 lbft) 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).

DIESEL ENGINE

3. Disconnect the return hose.

4. Disconnect the pressure hose.

5. Access to remove the three bolts securing the pump to the cylinder head can be gained thru the pulley holes.

6. Loosen the pump bracket to the block.

7. Remove the 6 intake plenum bolts (1).

8. loosen the inner cooler tube clamp at the intake

plenum and remove the intake plenum.

9. Loosen the inner cooler tube clamp at the radiator

support side and remove the tube from the vehicle.

10. Remove the power steering pump (2) from the top

of the engine compartment where the intake ple-
num was.

INSTALLATION

GAS ENGINE

1. Align the pump with the mounting holes in the left

cylinder head.

2. Install 3 pump mounting bolts through the pulley

access holes (1). Tighten the bolts to 28 N·m (21 ft.
lbs.).

3. Reconnect the pressure line (4) and return hose (3)

to the pump and reservoir (2). Tighten the pressure
line to 37 N·m (27 ft. lbs.).

4. Install the serpentine drive belt, (Refer to 7 -

COOLING/ACCESSORY DRIVE/DRIVE BELTS -
INSTALLATION).

5. Fill the power steering pump, (Refer to 19 -

STEERING/PUMP - STANDARD PROCEDURE).

DIESEL ENGINE

1. Set the power steering pump (2) in place in the

engine compartment from the top.

2. Install the inner cooler tube.

3. Tighten the inner cooler tube clamp at the radiator

support side.

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 of the cap is normal. The fluid level should read between the ADD and
the FULL COLD marks. When the fluid is hot it should read between ADD and FULL HOT marks. Only add
fluid when the vehicle is cold.

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: FLUID LEVEL SHOULD BE CHECKED WITH THE ENGINE OFF TO PREVENT PERSONAL INJURY
FROM MOVING PARTS.

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.

PUMP

DR/DH

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

REMOVAL

1. Drain and siphon the power steering fluid.

2. Disconnect the return and supply hoses connected to the power steering fluid cooler.

3. Remove the mounting bracket bolts (2) securing

the fluid cooler (1) to the brace. (V6&V8)

(Diesel engine)

4. Remove the fluid cooler from the vehicle.
