How to Install a Windshield Washer Reservoir in 5 Steps

The windshield washer reservoir equipped on your auto holds the washer fluid until you squirt it on the windshield. You see, it is important to keep this reservoir in good shape; otherwise, you risk compromising your safety, especially when dirt or any other obstruction blocks your view. Over time, the tank may get damaged and punctured, causing the fluid to leak out. Sometimes, patching the part will repair it, but if it is already severely damaged, then you have no option but to install a new one. Here is a five-step guide in installing a new windshield washer reservoir.

Required skill level: Novice

Needed tools and materials

  • Car jack

  • Jack stands

  • Wrench

  • Screwdriver

  • Seals
  • Locating the windshield washer reservoir

    Find the location of your windshield washer reservoir through your owner's manual. The part is commonly located under the hood, but it is sometimes accessed through the fender well.

    Jacking up the vehicle

    Some cars only require you to unscrew the part from above, but other types are accessed from beneath the car. So to install a new one, you will have to jack up the auto. Do not forget to secure it with a jack stand for safety reasons. Once done, remove the right or left front tire of your auto, depending on where the manual says the windshield washer reservoir is located.

    Removing the inner fender line

    To access the windshield washer reservoir easily, remove the fender line with a screwdriver. The part should have fasteners and screws to facilitate its removal.

    Disconnecting the hose, mounting bolts, and tank

    Once the fender line is removed, the windshield reservoir should now be accessible. But before removing the part, remember to disconnect the negative cable on the battery and the electrical connector first. Afterwards, unscrew all the leads to the reservoir. This should include the hose and mounting bolt. Once done, remove the damaged reservoir, including the seals.

    Assembling the new windshield washer reservoir

    After the damaged stock windshield wiper reservoir is removed, screw the new one in place. Do not forget to reattach the hose and replace the mounting bolts and other leads. Afterwards, assemble the electrical connector and battery back in their original setting.

    • Dorman vs. Omix: Who Makes the Better Windshield Washer Reservoir?

      Leaks in your auto's windshield washer system are fairly common. These leaks are often caused by a faulty windshield washer reservoir. Luckily, most of the damage can be easily repaired. But if you want a sure way to prevent constant servicing of the part, then you had better select the right type of reservoir for your vehicle. These plastic pieces are not complicated parts. Even so, there are some things you might want to consider when buying one. If you want an informed decision in choosing the right brand, then here is a quick comparison and contrast between the two leading brands in the reservoir market.

      Package deal

      The windshield washer reservoir is made up of several parts, which are not exactly sold as one unit by most auto manufacturers. The Dorman brand offers the windshield washer reservoir with its corresponding cap. Although it does not sell the tank with its motor and fluid sensor, Dorman is still a better choice than Omix because the latter sells the reservoir individually, without the cap, motor, and fluid level sensor.

      WINNER: Dorman

      Pricing and affordability

      Even if Omix windshield washer reservoir manufacturers do not sell the part with caps, they come a little less expensive than the Dorman brand. You see, Dorman reservoirs usually cost around 50 to 100 USD while Omix sells the part at around 30 to 50 USD. The difference is not really huge, though it can be a big deal for those with limited budget.

      WINNER: Omix


      Dorman windshield washer reservoirs are sold with a longer warranty. In fact, most of their parts come with a lifetime limited warranty. Compared to Omix windshield washer reservoirs' three-year limited warranty, Dorman's offer is a safer and better choice for car owners.

      WINNER: Dorman

      The verdict

      While both brands are known for their high-quality windshield washer products, the Dorman brand comes a notch higher with its better warranty offers and package deals. When it comes to durability, both parts seem to last long, so it's still a win-win situation. You see, both products have their boons and banes. Choosing the right one for your auto depends mostly on your preference.
