I've had a CSI water pump on my 474 for about 4 years now and it has worked perfectly. Sunday, however, while in staging, I watched the temperature gauge(s) go from 155 to 210 in about 15 seconds. Fortunately, I just happened to be staring at the gauges at the time. The water pump had stopped!
By pulling on the wires that go into the bottom of the pump off to the side, the pump would resart and continue to run. A little help from the "racers friend" (duct tape) and I was able to finish out the day without any more problems. Last night I took the pump motor apart and found a small amount of corrosion on the push-on terminals. After cleaning and reseating, the pump worked fine, but just to be sure, I soldered all the wires on the 5 or 6 push-on connectors inside the pump. There was no corrosion inside the pump, as if it had been exposed to any dampness, only corrosion on the terminals...... SO, if you've got a CSI pump thats a few years old, you might want to check/solder these wires on as preventative maintenance item. -- Bill -- GT37 3600lbs...as featured on the cover of Pontiac Enthusiast Jan/Feb 2002 DOT/mufflers-all motor 6.49 @ 108 10.14 @ 133

Dielectric grease will solve that problem I would think.....we use it where I work, on connections for sensors and such to prevent corrosion.These parts are exposed to a mixture of water and sodium 24hrs a day 5 days a week and 12 hrs a day on saturday and sunday and the stuff works like a dream.
Just an idea....better than having to solder it together.At least this way you can get it apart easy if you need to work on it. Colin

It might not have been corrosion but Electrolisys. This happens over time when two different metals are touching each other, such as brass lug on wire and post being made of steel.

Hey Tikiklubracing,
What does the name stand for and what's the 4 door? The pic is too small to tell.

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
