I just replaced the water pump on my 2011 today. Took me about 1.5 hours and was 150$ from Amazon. Aisin pump.
Replace water pump. 100% oem or aisin.
Use a good pump like a Aisin, cause you don’t want to do it again in a year.
When I bought Aisin water pumps for some of my other Toyota/Lexus vehicles, the embossed Toyota emblem on the pump would be ground off.
Get the Aisin one off rockauto, I just replaced mine with it.
Once I removed the thermostat, I felt in the port and although the impeller felt ok, it spun freely; not smooth like a bearing but rough like it was dragging. Since I was able to freely turn the impeller through the thermostat hole, I have to assume my water pump is failed.
My 1 year, \~6K miles Aisin WPT-108 pump failure story:
I have a 4A-FE Corolla E11. Changed timing belt, auxiliary belts, tensioner+spring, the whole lot last summer. The waterpump (Aisin WPT-108) was from a reputable online shop here in Europe (Autodoc). Last week I come to find the new pump dripping from the lower weep hole, so its the whole timing belt job all over again pretty much. No wierd bearing sounds. I did 6K miles last year if that.
I had a gates kit on my Subaru and the water pump failed and leaked after less than 1000 miles.
The water pumps i’ve seen leak a few times on the v6 hondas.
Gates is crap. Bought their water pump and it failed less than a year and leaked the whole time.
