Water pump OEM FORD or Pierburg

The Pierburg pump is an all aluminum upgrade. I put one in a couple months ago. It works great, less prone to leaking and I have only ever read/heard good things about it. It is even a few dollars cheaper than the OE VDO pump.

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.

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.

I too chose pierburg from fcp. Questionable weather it\u2019s any better than oem. I appreciated the all aluminum housing of the pierburg as it provides one less failure point which is the possibility of the plastic cracking due to an over torqued hose clamp.

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.

The 3.5 engine is garage with this design. Had an Edge from new and out 150,000 miles on it in 13 years. I was always dreading this failure and luckily dodged it before selling it.

Awful design by Ford to put the water pump inside the engine. I almost bought one of these used a few years ago, but backed out after reading about 3-4k jobs to replace a water pump at 180-100k miles.

Pretty sure this is the motor that needs the engine dropped to do waterpump and timing components. Bad bad design

The 3.5 5th generation Explorer has an internal water pump driven by the timing chain. It’s an enormous pain to change requiring significant disassembly (nearly 12 hours of labor) and generally includes replacing the timing chain in the process since you’re already in there, plus when it fails it can easily mix the coolant with the oil and destroy the engine, all that’s keeping them apart is a little seal.
