Coolant pump impeller R&R

The GMC came with a cast 4.25" water pump impeller. This can be swapped to a replacement water pump. Replacements mostly have a stamped open back impeller of a smaller diameter.

       

 Original 4.25" cast impeller compared to the generic 3.875" impeller

I set the clearance .015" minimum. Using a pump affinity calculator like-

https://en.wikipedia.org/wiki/Affinity_laws


Changing only the impeller diameter makes around a 12% difference in pressure.

               Speedo gear gave out but I had a new one!

   Cruise control gave out in multiple ways... Foam filter deteriorated enough that the solenoid couldn't pull in, removed. Minimum speed switch went erratic so it got jumpered with a paper clip at the transducer. Stalk switch went out so it was replaced with a door bell button for engage and jumpered the hold part to always be on. Still turns off with the brake pedal. Love my auto throttle.
