Reviews of AISIN water pump

My impression was (recommended by many) this specific seller had everything OEM, water pump was the correct Aisin one.

RockAuto Aisin with the logos ground off. That’s when you know it’s the real deal.

Aisin is of course the manufacturer of the defective one you are replacing. So there is that.

Aisin only. It's the Oem.

Aisin TKF-005 has the 2 port pump and is otherwise identical to TKF-004 with the 3 port pump.

Mine started leaking around 145,000 due to bearing play. It is a do-able DIY driveway job.

Bought an Aisin waterpump off ebay and installed during the swap but it is making an awful racket and has me concerned it is a fake or otherwise defective out the box. Not sure how to share a video here but it sounds like a loud buzzing and i dont remember the old waterpump making that noise.

Yes, Aisin TKH-002. I personally would only buy from Napa store or Carid.com. Napa is listed as authorized retail for my state. I personally wont trust rockauto for critical parts like this, I have has two experiences with previously used/tampered products from them. I can pay a little more from Carid.com and they shipped directly from Aisin warehouse, not Rockautos random low bid distributor. Amazon and Ebay have a bad reputation for fakes, no personal experience with that.

I use the same exact part that you bought. On mine I could see where they removed the word Lexus or Toyota from the mold. It's the same part as OEM. I replaced the water pump myself and it wasn't too bad but some of the bolts are difficult to get a socket on.

I used binder clips to hold the timing belt on the driver side cam gears instead of purchasing the tool. Purchased OEM thermostat from dealership and Aisin water pump / timing belt kit from RockAuto. First time doing one, was easier than I thought it was going to be.
