What is a windshield washer reservoir?
The windshield washer reservoir—also called the windshield wiper fluid reservoir—is a 1- to 1.5-gallon plastic container that houses the cleaning fluid for your windshield. It works together with other components of the windshield washer system, including the windshield washer pump and nozzles, to keep your windshield clean.
The fluid is responsible for removing all kinds of dirt and grime to ensure you can see the road ahead of you, and the reservoir itself is resistant to antifreeze and ethanol.
When should I replace the windshield washer reservoir on my car?
The plastic walls of your windshield washer reservoir can crack or break if you run out of washer fluid. The mounting holes can also break as the vehicle vibrates and loosens the bolts holding the reservoir in place, causing the reservoir to be incapable of holding washer fluid.
If you have a broken windshield washer reservoir, you might encounter the following:
Low or no pressure when activating the windshield washers
Having to refill the reservoir more than usual
Wiper fluid leakage underneath your vehicle
How often should a windshield washer reservoir be replaced?
Windshield washer reservoirs are meant to last many years, if not the lifetime of your vehicle. However, they can wear out or become damaged, so it’s best to watch for signs of a broken windshield washer reservoir to know when a replacement is necessary.
Can I replace my windshield washer reservoir myself?
Your vehicle’s windshield washer reservoir is a fairly easy part to replace, so you can complete the job at home. However, your vehicle will determine the ease of the replacement—for example, the windshield washer reservoir on a Honda Civic or Toyota Camry will be much easier to replace than a Porsche or BMW’s.
