    Q:
    How to replace the Windshield Washer Pump motor and Windshield Washer Reservoir on Ford Ranger? Posted by Xristos G.
    A:
    Insert a small screwdriver and release the electrical connector tabs then disconnect the electrical connector of the Windshield Washer Pump. Disconnect the small hose at the base of the Windshield Washer Reservoir and pump motor assembly and cover the hose to avoid any spillage of the fluids Removal of two screws holding the Windshield Washer Reservoir and pump motor assembly to the fenderwell will see the component come off. Dump the washer fluid in a clean container for its reuse in case it is not contaminated. Remove the seal ring by twisting and pulling the pump motor out of the reservoir receptacle with special attention taken to the fact that in later models, the rubber grommet could be used instead of the seal ring and consequently does not need to be removed. Take hold of one wall round the electrical terminal with pliers and draw out the motor, seal and impeller assembly out of the reservoir with one condition, that if the impeller and seal come apart, you could join them again. To ensure that the reservoir is clean free from debris, it should be rinsed with water and checked for things such as inclusions. Check the pump chamber, if the motor you are going to install is old, clean the chamber if needed. Assembling this device is quite easy; you should apply powdered graphite on the outer side of the seal so that you will easily place it well onto the two halves of the motor end cap and when placing the seal ensure that the small projection fits into the slot in the reservoir before the seal is placed firmly. By tightening the retaining ring to the motor and the plate with the help of the 1-inch 12-point socket the hose should be connected to the fitting which is situated at the bottom of the reservior and finally the reservior should be fitted in the engine compartment with the two screws. Last but not the least, plug in the electrical connector while on the same note it is advised not to activate the pump should the reservoir isn't filled. Next, fill up the reservoir, turn on the pump and look for the leaks.
