REMOVAL AND INSTALLATION

Motor, Seal and Impeller Assembly

 

Removal and Installation

  1. Disconnect electrical connector.
  1. Remove reservoir assembly from vehicle. Disconnect electrical plug and hose.
  1. Using a small-blade screwdriver, pry out retaining ring.
  1. Using pliers to grip one wall around the electrical terminals, pull out the motor, seal and impeller assembly. If the impeller and seal come off when the motor is pulled, they can be reassembled. Make certain the reservoir pump chamber is free of foreign material prior to installing the old motor in the new reservoir.



  1. Before installing the assembly, lubricate the outside diameter of the seal, with a dry lubricant such as powdered graphite. This will prevent the seal from sticking to the wall of the reservoir motor cavity and make assembly easier.
  1. Align small projection on the motor end cap with the slot in the reservoir, and assemble so that the seal seats against the bottom of the motor cavity.
  1. Using a 1-inch socket (preferably 12 point), hand press retaining ring securely against motor end plate.
  1. Connect hose. Install the reservoir assembly in the vehicle.
  1. Fill the reservoir and operate the washer system.
  1. Check for leaks and hose kinks.

     CAUTION: Do not operate pump until fluid is added to reservoir.
