2016 F80 M3 Mechanical Waterpump How-To

[Matt214]

Hi everyone, I recently discovered that I have coolant leaking from my mechanical waterpump. So, I have a new pump and also a thermostat since it would make sense to do both at the same time at 106K miles. My question is, has anyone found any how-to's or videos on this particular repair? I'm fairly experienced with doing repairs on this vehicle as well as others so really just wanted to find a guide of some kind so I could eliminate 'bumping into walls' if at all possible. The pump isn't exactly in a convenient area so wanting to go in with some kind of insight if I can. I've done a lot of Google Searching and also searching within the forums here and haven't found anything.

Any help is appreciated and if we don't have a how-to anywhere, perhaps I could create one for everyone else who needs to venture down this path.

Thanks in advance!

I’ve been looking for the same. Actually all the pumps on my 2016 are old

In another thread, a forum member shared where someone did a write up for the pump and that is here:

I also found this YouTube video, explaining the auto-tensioning water pump pulley, useful as well and that is here:
