NOZZLE, Washer

FRONT

FRONT

The fluidic front washer nozzle (1) is constructed of molded plastic and has in integral latch feature (2) that secures it in a dedicated mounting hole located at the center, rear edge of the hood panel near the windshield. The domed upper surface of the washer nozzle is visible on the outside of the hood panel, and the nozzle orifice (4) is oriented towards the windshield glass.

The washer plumbing fitting (3) for the washer nozzle extends below the hood panel and is accessible from the engine compartment.

The front washer nozzle cannot be adjusted or repaired and, if ineffective or damaged, it must be replaced.

REAR

REAR

The fluidic rear washer nozzle (2) is constructed of molded plastic with an integral metal orifice insert (3). The rear washer nozzle is integral to the rear wiper motor output shaft and is visible through a cutout in the rear wiper arm nut cover (1) on the upper left corner of the outer rear lift glass. The nozzle orifice is oriented toward the lower path of the rear wiper blade on the lift glass and moves in concert with the rear wiper motor output shaft and the rear wiper arm.

The rear washer nozzle receives washer fluid through the rear wiper motor output shaft. Washer fluid is supplied to the rear wiper motor through the hardtop washer hose (3) which is connected to a molded plastic barbed fitting (2) on the motor transmission housing (1) on the upper left corner of the inner rear lift glass. The washer supply hose and rear wiper motor are concealed on the inside of the lift glass by a molded plastic trim cover.

The rear washer nozzle cannot be adjusted or repaired and, if ineffective or damaged, the rear wiper motor unit must be replaced.

FRONT

FRONT

The front washer nozzle is designed to dispense washer fluid into the wiper pattern area on the outside of the windshield glass. Pressurized washer fluid is fed to the nozzle from the washer reservoir by the washer pump/motor unit through a single hose, which is attached to a barbed nipple on the washer nozzle below the inner hood panel. A fluidic matrix within the washer nozzle causes the pressurized washer fluid to be emitted from the nozzle orifice as a fan-like stream to more effectively cover a larger area of the glass to be cleaned.

The rear washer nozzle is designed to dispense washer fluid into the wiper pattern area on the outside of the lift glass. Pressurized washer fluid is fed to the nozzle from the washer reservoir by the washer pump/motor through a single hose, which is attached to a barbed nipple on the back of the rear wiper motor transmission housing cover. A fluidic matrix within the nozzle causes the pressurized washer fluid to be emitted from the nozzle orifice as an oscillating stream which, when combined with the wet arm-like movement of the nozzle with the rear wiper motor output shaft, more effectively covers a larger area of the glass to be cleaned.
