Windshield Washer Spray Nozzle: Description and Operation
Front
Pressurized washer fluid is fed through a single hose, attached to a barbed nipple on the front washer pump. The hose is routed to a tee fitting
located near the rear inner hood panel reinforcement. Hoses from the tee fitting are routed to the two nozzles.
A check valve is located in the washer supply line near each of the two front nozzles, which prevents washer fluid drain-back or siphoning from
occurring.
Windshield Washer Nozzles
The nozzles are snapped into openings in the hood panel below the windshield The two washer nozzles each emit two streams of washer fluid into
the wipe pattern. If the aim of the washer fluid streams is unacceptable, each stream can be adjusted using a pin inserted in the nozzle orifice to
rotate the nozzle ball.
The nozzles, check valves and hose fittings cannot be repaired and, if faulty or damaged, they must be replaced.
Rear
Pressurized washer fluid is fed through a single hose, attached to a barbed nipple on the rear washer pump. The hose is routed from the front of the
vehicle to the lift glass with the left body wire harness. At the left rear corner of the hardtop, the hose connects to a check valve, which prevents
washer fluid drain- back or siphoning from occurring.
Rear Washer Hose Cap
There is also a washer hose cap attached to the hose below the check valve. When the hardtop is removed from the vehicle, the body half of the
washer hose must be disconnected from the check valve. The washer hose cap is used to plug the body half of the washer hose after it is
disconnected from the check valve.
From the check valve, another single hose is routed through the rear lift glass opening reinforcements of the hardtop to the rear wiper motor cover.
Behind the rear wiper motor cover, the hose attaches to the rear washer nozzle nipple.
