How do you change the windshield washer reservoir tank in 2007 Toyota Avalon?

Answer 1

If you are not sure if the tank itself is the problem you can check fairly easily to see if the hose has slipped off the nipple at the tank bottom of the tank, which is what happened to my 2007 Avalon. You will need either a Phillips head screwdriver or a 10mm metric wrench and a flashlight. Turn the front tires as if you are making a left hand turn. Underneath the car, in front of the passenger side wheelwell, remove the screws holding the underside plastic road shield to the frame. There are a bunch of screws holding it but you should only need to remove the two holding the right rear end of the shield (near the wheelwell) to the frame. I removed three more going along the front side of the road shield as well as one wheelwell flap bolt, but don't think that it was necessary. Pull the wheelwell flap back (toward the tire) and you will be looking right at the hose connection to the tank. As far as I could tell, the hose slips on without a clamp, like the old vacuum hoses did. Not sure about this (the clamp) since it's the weekend and Toyota service is closed, but you could call your local Toyota service department and they are usually very helpful with stuff like this.

Hope this helps,
