Replace the windshield washer pump on a 1994-2007 Dodge Ram 2500 with 5.9L Cummins diesel engine. This involves draining the washer reservoir, disconnecting electrical connections, and removing the pump from the reservoir.

Warnings

Tools required

Parts

• Windshield washer pump × 1 — Mopar 55077073 or equivalent
• Washer reservoir grommet (if damaged) × 1 — Use OEM specification

Fluids

• Windshield washer fluid (all-season) — 4 qt

Preparation

1. Park vehicle on level surface and engage parking brake
2. Open hood and support with hood prop
3. Disconnect negative battery terminal using 10mm socket
4. Locate washer reservoir on driver's side inner fender well
5. Place drain pan under reservoir area to catch fluid

Procedure

1. 1

   Drain washer reservoir
   Disconnect the washer fluid hose from the pump outlet at the reservoir. Use needle-nose pliers to compress the hose clamp and slide it back on the hose, then pull the hose off the pump outlet. Allow fluid to drain into the drain pan. Alternatively, use a fluid transfer pump to remove the washer fluid before disconnecting the hose.
2. 2

   Remove reservoir access
   Depending on model year, you may need to remove or reposition the inner fender splash shield for better access. Remove plastic push clips or screws securing the splash shield using a flathead screwdriver. Fold shield back to access the washer reservoir and pump location.
3. 3

   Disconnect electrical connector
   Locate the electrical connector on the washer pump. Press the locking tab on the connector and pull straight off the pump terminals. The connector is typically a two-wire connector located at the bottom of the reservoir.
4. 4

   Remove washer pump from reservoir
   The pump is held in the reservoir by a rubber grommet. Grip the pump body firmly and pull straight out with a twisting motion to break the grommet seal. If the pump is stubborn, carefully pry around the pump base with a flathead screwdriver, working around the circumference to avoid damaging the reservoir. Remove the pump and attached grommet.
5. 5

   Inspect grommet and reservoir
   Inspect the rubber grommet for cracks, tears, or deterioration. If damaged, replace the grommet with a new one. Clean the pump mounting hole in the reservoir, removing any debris or old rubber residue. Inspect the reservoir for cracks, especially around the pump mounting area.
6. 6

   Install new washer pump
   If the grommet is being reused, lubricate it lightly with soapy water or silicone lubricant. If installing a new grommet, seat it onto the new pump body first. Align the pump with the mounting hole in the reservoir and push firmly with a twisting motion until the grommet seats completely and the pump is flush with the reservoir. Ensure the pump outlet is oriented correctly for hose connection.
7. 7

   Reconnect electrical connector
   Push the electrical connector onto the pump terminals until it clicks into place. Verify the locking tab is fully engaged. Tug gently on the connector to ensure it is secure.
8. 8

   Reconnect washer hose
   Push the washer fluid hose onto the pump outlet firmly. Slide the hose clamp forward over the connection point using needle-nose pliers. Ensure the hose is seated completely on the pump outlet barb.
9. 9

   Reinstall access components
   Reposition the inner fender splash shield if it was removed or moved. Reinstall all push clips or screws to secure the splash shield in its original position.
10. 10

    Reconnect battery and refill reservoir
    Reconnect the negative battery terminal and tighten to specification. Fill the washer reservoir with fresh all-season windshield washer fluid to the full mark (approximately 4 quarts total capacity).
    Torque spec

    Battery Terminal Bolts6 Nm (4 lb-ft)

Reassembly

1. Ensure all electrical connections are secure and fully seated
2. Verify washer hose is properly clamped and not kinked
3. Check that splash shield is properly secured and not interfering with moving components

Verification

• Turn ignition to ON position (do not start engine)
• Activate windshield washer switch and verify pump operates smoothly without abnormal noise
• Check that fluid sprays from both windshield nozzles with adequate pressure and pattern
• Inspect pump area, hose connections, and reservoir for any fluid leaks while pump is running
• Verify reservoir fluid level has not dropped excessively, indicating leaks
• Turn off ignition and close hood
