OEM. Went aftermarket 2 times in a year replacing that pump. Finally bit the bullet and paid for toyota part.

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.
That looks like the water pump but I can be wrong. Also, there is no dipstick for the transmission anymore. Depending on the engine, there is a drain bolt on the side of the transmission on the driver side I believe near the drivetrain.
How many miles do you have? Its probably time to change the water pump if it's making noise and if it is, it needs to be replaced before it causes a whole world of hurt to your wallet.
Had a friend rebuild his 22RE, guy ordered his parts from eBay. Parts to replace which I believe is a must, water pump, t-stat, oil pump, timing chain and tensioner.
Over the weekend this is how I did the water pump. I didn't have 2 hydraulic jacks, so I had to come up with some other idea. When I took out the water pump, I think the seal was starting to leak. Cleaned up area and reinstalled with new water pump.
I've also got a bad water pump.
