What to know about the Windshield Washer Reservoir:
Windshield washers serve a simple yet extremely important purpose. A dirty windshield obstructs the driver’s view. They are vital especially in very cold climates or in areas with a lot of dirt roads. The windshield washer reservoir holds the fluid that is sprayed onto the windshield. The windshield washer reservoir is usually made of a white, semi-transparent durable plastic and will often have a black or colored plastic cap. The capacity of the fluid reservoir rest on on the make and model of your vehicle, but usually ranges from 1 to 1.5 gallons.
Facts to Note:
Frozen washer fluid is a big contributor to cracks in the reservoir.
Different washer fluids are approved for different seasons; make sure to use the correct season’s fluid.
Maintenances may slow the leaking, but most cracked reservoirs need to be changed entirely.
How to Fix:
The vehicle hood is raised and secured in the open position
The windshield washer reservoir is unbolted from inner fender and removed
The washer lines are cleaned and flushed out
The new washer reservoir is connected and fixed then filled with washer fluid
The wipers and washers are tested for proper operation
Read your owner’s manual to see if the manufacturer suggests certain fluids for certain reservoirs. For example, the reservoir to headlight-mounted washers may only take non-freezing fluid as the headlights do not get as warm as the windshield in cool weather. Have one of your expert mechanics inspect the whole windshield washer system when examining the reservoir. A reservoir with a crack should be changed.
Common symptoms indicating you may need to change the Windshield Washer Reservoir:
Low or no pressure when activating the washers
Fluid leaking out from under the vehicle
Filling the reservoir more often than usual
Sprayers don’t spray far enough on the windshield or do not spray enough fluid
Importance of this service:
This service is fairly important to the average driver and very important to those in cold climates or in areas with lots of dirt roads. Both road salt and ice can obstruct a windshield without anti-freezing washer fluid in the reservoir. Dust and mud can become too thick to wipe away with just the wipers.
