🚗 Toyota Lexus 85321-28020 NEW Koauto Wiper Washer Windshield Check Valve: A Reliable Solution Review

- Easy install in about ten minutes (get a cheap fairing remover/trim kit that will get to the washer hoses without destroying the plastic fairing clips) - Installed this a few months ago before and works like a charm

The valve came out fine, easy to replace, unfortunately it only lasted about a week before my washer fluid completely shut off and I had to replace it again. Just buy a genuine replacement for a few dollars more!

Very easy to install, I just sprayed silicone grease on the tubes and they came loose with a medium jerk. Then connect the new part the same way as the old one and you're done.

Only 3 stars because the product had two pinholes that sprayed when the washer pump was running. I fixed it with the plastic repair epoxy I had. Otherwise I was satisfied. If I wasn't a comfortable person, I would get even more upset. Many Thanks.

Replaced when the wipers stopped working and line pressure due to clogging caused the line to break at the connector. All lines and nozzles were clean so a check valve should have been present. While cleaning the check valve I dropped it in the engine bay and couldn't find it. I ordered a new one and it's back in business. You never realize how much you miss something until it's gone.

OK, OK - I am NOT using this for an OEM application. I needed a one way valve for a Longbridge manual washer on a 1959 Austin Healey 100-6. But we need all the volume this valve can easily miss. I was surprised at how much unnecessary back pressure the valve has due to the overly heavy check valve spring. Okay --- if you have an electric pump, you're probably fine. But why do you have back pressure? Ok, I'll try another one. $3.98 isn't bad for R&D!

I used this to repair the injectors on my 2008 RAV4. Problem: After trying to use windshield wiper fluid, I got a slight pull on the driver's side and none on the passenger side. After the initial jerk of the driver, it stalled and stalled. I asked my wife to push the button to use the spray while I listened to the washing machine motor. It sounded like it was activated. The rear window also worked perfectly (despite being fed from the same reservoir). It literally took 5 minutes to change and…

So I had a 2015 Toyota Corolla and this part seems to be a common failure point. I read that there is some kind of valve in this thing that fails after a while, in my case 4.5 years. My brother has the same car and model and he messed it up too. As a result, one of the washer jets produces almost no liquid while the other jets spray more than usual. Work. Each nozzle is connected to this part with a rubber hose, so I swapped the hoses around and tested. As a result, the opposite nozzle is now…
