    • 1). Open the hood and locate the negative battery cable from the negative battery terminal, using a wrench to remove the retaining bolt. Isolate the battery cable from the battery while you are working.

    • 2). Locate the windshield washer reservoir on the driver's fender just in front of the firewall. Remove the three reservoir mounting bolts with a socket and ratchet then carefully remove the reservoir from the fender.

    • 3). Pull the two rubber hoses off the outlet fittings on the washer pumps located on the bottom of the reservoir. Washer solvent is going to leak out of the fittings so place a clean drain pan or bucket under the pumps and allow the reservoir to drain completely.

    • 4). Disconnect the electrical connector on the bottom of the pump by releasing the locking tab then pull the connector off the pump. Lay the wiring harness connector aside for now.

    • 5). Open the fill hole on the top of the reservoir and insert a socket on an extension and a ratchet into the reservoir then remove the nuts from inside the reservoir. Remove the pump from the bottom of the reservoir and discard it.

    • 6). Position a new pump into the holes in the base of the reservoir and attach the retaining nuts using the long extension on a socket and ratchet to reach the pump from inside the reservoir. Tighten the nuts until they are snug but do not over-tighten them or you will crack the plastic reservoir.

    • 7). Push the wiring harness connector onto the new pump then connect the rubber hose to the outlet fitting. There is no clamp on this fitting, just push it all the way onto the fitting and the two barbs will hold it in place.

    • 8). Position the reservoir on the fender and install the three retaining bolts. Tighten the bolts with a socket and ratchet. Refill the reservoir with windshield washer solvent, close the lid and check for leaks. Turn the ignition in the Jeep on and push the washer switch to ensure it is working. It may take a minute for the air to clear out of the line, so don't be alarmed if you don't get solvent right away.
