Replacing the washer jets on a 1990 Jaguar XJ40 is a fairly simple job if you know how to use a screwdriver, have some patience, and a bit of strength. For the job, you will need a 17mm wrench and a set of Torx screwdrivers. At the time of this repair, the dealership was able to special order replacement washer jets for approximately $70 each. However, a good used jet can be acquired for $20 online (EverydayXJ). It is also recommended that you purchase the plastic piece designed to cover the washer jet. Otherwise, it is very easy to accidentally knock off the snap-fitted spray nozzle when scraping snow and ice off the windshield. I recently found several on eBay for $10 each.
The job can be divided into the following steps:
- Open the hood of the vehicle.
- Remove the plastic cover from the bottom of the windshield wiper. Do not pry with a screw driver. Simply pull the cover toward the right hand side of the car. You may need to lift up and out at the same time.
- Remove the 17 mm nut which holds the wiper arm to the wiper transmission bolt.
- Remove the wiper arm.
- Remove the five torx screws which hold the plastic cover to the bottom of the windshield.
- Raise the plastic cowl a few inches from the windshield and turn over toward the front of the car. Note that the washer jets are still connected to the cowl at this point.
- Disconnect the electrical connectors for each washer jet. Be careful not to break the plastic tabs on either side.
- Disconnect the plastic water hose from each washer jet. This may prove to be the most difficult part of the job. You will need both strength and perseverance. After completing this step, the plastic cowl is completely separated from the car.
- Locate the base of the washer jet on the bottom side of the cowl.
- Press the washer jet’s plastic tab inward and push the entire assembly upward through the hole.
- Installation is accomplished by the same steps in reverse order.
