So - a side note on water pumps. I won't put a junk water pump in my car, and as such this was quite a search for a new one as i didn't want a Chinese part.

After quite some investigation, and hands on inspection, I was able to see that:

A) The Bosch water pump is now made in China. It used to be USA. All of the samples of this water pump appeared to be horrible. Stamped impeller

B) The GMB water pump was also made in China by a different maker than the Bosch. It had more sharp edges, but appeared to be better made. It used a cast iron vane for it's impeller.

C) Saleri water pump was made in Italy. Easily the best of these three pumps.

D) End users reported having to modify the Graf water pump to get it to work. I'm not certain why, or if the saleri will also need this attention. If so, I will post pics.

E) The Gates pump was also made in China and was blatantly a GMB pump rebranded.
