Water pump OEM Toyota or Pierburg

Pierburg. It’s literally exactly the same just no BMW logo.

Pierburg is the OEM maker of the BMW water pump. Spending the extra for the BMW is ridiculous when they are 100% the same exact same pump from the same company from the same factory.

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.

I'm working on adapting these water pumps to a variety of older engines. This one will be going on a Chevy LSx. The pumps support two different control schemes; one via PWM (no feedback) and one via LIN. I will be working on reversing the LIN communications and building a more sophisticated controller soon.

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.

PIERBURG makes a good water pump...

It happens. I’ve had maybe 3-4 do this out of probably 300 we’ve changed at the shop. Once was a pierburg but the rest were autozone duralast etc.

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.

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

I picked the pierburg for all aluminum casing and impeller. They were both about the same price last time I needed to get one. Note that the pierburg failed at not even 10k miles. I replaced with another pierburg chalking it up to bad luck. The only advantage I can think of with the pierburg is the fact that you can torque down the hoses that use clamps and not have to worry about cracking the housing. But in reality doubtful that is a risk. Also it won’t be in service long enough to get brittle enough to matter.
