Replacing the Jägermobile Water Pump Again!

[Topless]

It might be production quality, it might not. Three things will drastically shorten the life of a water pump and one is quite common.

1. Corrosive coolant

2. Too much pulley tension

3. An air bubble trapped in the WP causing it to fail to prime and score the shaft seal.

I use only Porsche coolant, same belt/size and tension pulley, and I always bleed the coolant system if I performed work on the system.

No leak this time, just noisy, the bearings are going out.
