Front Windshield Washer Pump - Description

FRONT





The front washer pump/motor unit (2) is located just forward of the rear washer pump/motor unit (3) of vehicles so equipped on the top of a sump area on the inward facing side of the washer reservoir (1) in the left front corner of the engine compartment. A small permanently lubricated and sealed electric motor is coupled to the rotor-type washer pump.

An inlet nipple on the bottom of the pump housing passes through a rubber grommet seal/filter screen installed in a dedicated mounting hole of the washer reservoir. When the pump is installed in the reservoir the barbed outlet nipple on the pump valve body housing points rearward and connects the unit to the front washer hose.

The front washer pump/motor unit is retained on the reservoir by the interference fit between the pump inlet nipple and the grommet seal, which is a light press fit. The top of the washer pump is also secured to the washer reservoir by a light snap fit into a receptacle molded into the reservoir that allows for mounting of the washer pump without the use of fasteners. An integral connector receptacle on the top of the motor housing connects the unit to the vehicle electrical system through a dedicated take out and connector of the vehicle wire harness.

The front washer pump/motor unit cannot be repaired. If ineffective or damaged, the entire front washer pump/motor unit must be replaced.
