There are pictures of a recently failed Bosch waterpump over here today:

After that I could drive it around for about 10 minutes or so and then it would heat up.

I pulled the Bosch water pump out today and the plastic impeller was broken and no longer turning with the shaft. It was still on the shaft at least, but no longer working. Now to see about getting my money back out of that pump. They have a 12 month warranty.

I just ordered the Hepu pump with the metal impeller. No more bosch pumps for me.

Please read the suggested threads and add value, either by pictures or by descriptions, so the next person stands on your shoulders.
