Windshield washer fluid is one of those maintenance items that you might overlook. Until you try to look through a dirty windshield while driving, that is.
You should check your windshield washer fluid whenever you fill up your fuel tank. If your washer fluid is low, refilling it is easy. Here’s how to do it.
There are a few things you should do before starting step 1:
Open your hood and find your washer fluid reservoir—it’s usually a white, translucent container with a windshield/water symbol on the cap. Note that if your vehicle has a rear wiper, there may be a second reservoir for it as well.
Remove the cap(s) and check the fluid level in the reservoir(s). If it's full, you don’t need to add any.
If the fluid is low, carefully pour some into the reservoir(s) until it almost reaches the top.
Replace the cap(s) and press down until it pops into place. Then, close the hood.
