PUMP

DESCRIPTION

Hydraulic pressure for operation of the power steering
gear is provided by a belt-driven all-aluminum power
steering pump. Most vehicles use a common droop
flow rate and constant displacement type pump that is
mounted in a common location (left front of engine).
The SRT8 power steering pump is a constant-flow
type, but appears the same externally and is mounted
in the same location as others.

DIAGNOSIS AND TESTING

PUMP LEAKAGE

The pump is serviced as an assembly and should not be disassembled.

Check for leaks in the following areas:

•

Pump shaft seal behind the pulley

•

Pressure and return lines

•

Flow control valve fitting

STANDARD PROCEDURE

POWER STEERING PUMP INITIAL OPERATION

WARNING: The fluid level should be checked with engine off to prevent injury from moving components.

CAUTION: Mopar

T

Power Steering fluid + 4 or Mopar

T

ATF+4 Automatic Transmission Fluid is to be used in

the power steering system. No other power steering or automatic 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 indicate COLD when the fluid is at normal
temperature.

1. Turn steering wheel all the way to the left.

2. Fill the pump fluid reservoir to the proper level and let the fluid settle for at least two (2) minutes.

3. Raise the front wheels off the ground.

4. Slowly turn the steering wheel lock-to-lock 20 times with the engine off while checking the fluid level.

NOTE: Vehicles with long return lines or oil coolers turn wheel 40 times.

5. Start the engine. With the engine idling maintain the fluid level.

6. Lower the front wheels and let the engine idle for two minutes.

7. 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 stand a few minutes and repeat the procedure.

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

REMOVAL
