Windshield Washer Pump: Description and Operation
Description
DESCRIPTION
The washer pump/motor unit (1) is located on the rearward facing surface of the washer reservoir, in the right (gasoline engines) or left (diesel engines)
front corner of the engine compartment. A small permanently lubricated and sealed electric motor is coupled to the rotor-type washer pump.
A seal flange with a barbed inlet nipple (6) on the pump housing passes through a rubber grommet seal installed in a dedicated mounting hole of the
washer reservoir. A removable molded plastic filter screen (7) inserted into the inlet nipple prevents most debris from entering the pump housing. When
the pump is installed in the reservoir a barbed outlet nipple (5) on the pump housing connects the unit to the washer system through a short washer
reservoir hose.
The washer pump/motor unit is retained on the reservoir by the interference fit between the barbed 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 the use of a snap post (2) on the motor housing and a snap post
receptacle molded into the reservoir that allows for mounting of the washer pump without the use of fasteners. An integral connector receptacle (3) on
the top of the motor housing connects the unit to the vehicle electrical system.
The washer pump/motor unit cannot be repaired. If ineffective or damaged, the entire washer pump/motor unit must be replaced.
