While I had the York AC compressor bracket off, I decided it was a good time to check the water pump. I had a new/spare sitting in a box and decided that new=more reliable... at least in the case of good parts.

After a thorough degreasing, I took out the bolts holding the water pump to its housing. I grasped the pump and gave a tug.... then a more firm tug/twist.... and nothing. The water pump would not budge. I looked more closely at the pump-to-housing area adn spied..... some of that gasket maker goo crap!!!

Nothing short of an air hammer or explosives will pull the pump off. Luckily it is not failing right now, so I put it all back together. But when it does, I guess that I'm in the market for a new pump housing, just to change the water pump.
