Replacing the squirters in your windshield washer system varies, depending on the make and model of your vehicle. Think of it as simply plumbing. Getting to the simple plumbing may be more challenging on some models. You’re going to have to inspect your car to determine what type of squirter you have and where exactly it is located to determine whether it’s something you can do yourself or decide to take to a mechanic and pay labor charges.
Locate the squirter heads for your vehicle. Some are on the wiper arms, some are on the surface of the hood and some are under the wiper arm cowlings. Determine where they are and what you have to remove to get to them.
Unclip the squirter from the wiper blade on wiper-arm-attached models, and skip the next step. For squirters on hoods, you may have to remove an insulation panel that may line the undercarriage of the hood and possibly cover the bottoms of the squirters. For squirters inside wiper arm cowlings, you’ll have to remove the plugs or screws that hold the cowling down in order to remove the squirter.
Squeeze the press locks on the underside of the hood or the cowling to release the squirter head from the hood or cowling.
Gently pull the squirter head away from the black rubber hosing.
Insert the new squirter head (on the wiper arm, on the hood or on the cowling) until it locks on and then reconnect the black rubber hosing and make sure the hose goes in flush.
Test the squirter to make sure it’s working, but keep in mind if the hood is open it may not be aimed correctly.
Aim the squirter (except on windshield wiper-arm-attached squirters) by pressing a small pick into the nozzle of the squirter head and manipulate the direction of the nozzle.
