Water pump AISIN or Hepu
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 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.
Ive reinstalled another new HEPU(made in germany) pump due to mileage. I don't think anything is wrong with the old one. When I cleaned the o-ring seal contact area on the block it was corroded right where it left an imprint.
Mine started leaking around 145,000 due to bearing play. It is a do-able DIY driveway job.
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.
My original plastic impeller pump failed at 145k miles. I replaced with with a metal impeller pump (Hepu IIRC).
If the hepu water pump I put on my 3.0T is anything to go by, I don't know that I would recommend them for chains.
I put a Hepu water pump in about 20k miles ago.
