Water pump AISIN or OEM Toyota

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.

I’m driving a 98 Toyota Camry and just changed the water pump at 300k(which includes changing the timing belt).

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.

If yours is the later style timing kit, get the Aisin kit from Rock. That kit is ALL OE supplier, including an Aisin water pump.

My Tundra was awesome, but guzzled fuel and I drive like an old grandpa. 13-14 mpg is expected. Also, Tundras are fairly expensive to maintain compared to Ford. My water pump went out and it was about $1k to get fixed.

My water pump was leaking this Fall at 235k. New mechanic showed me the leaky pump and it was oem toyota.

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