Please excuse my mechanical ignorance.
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.

It's not the goo-your problem is galvanic corrosion. When I pulled mine apart I had to take the whole assembly off the engine, soak the mating surfaces in Kroil, and then hammer-twist it while in a vise. There is a knob cast into the housing that allows you to hold it in a vise without messing up the mating surfaces. I lightly sanded down the mating surfaces before reassembly-it was definitely a press fit.

Ahh yeah, we have those 'type' of mechanics over here. They usually have their workshop attached to the side of a petrol station with a sign saying specializing in the following makes: and then every single car manufacturer will be under the list.
My first and last experience was bad enough where the mechanic welded my fan to the clutch in an attempt to overcome an overheat problem, needless to say it broke apart deaccelerating down a long hill piercing my radiator and denting my hood from beneath.

Thank you. I suspected that there was a simple way that I just wasn't thinking about.

From your first post and a later one.

You would be hard pressed to remove most water pumps by just pulling by hand even if gasket sealer was not used. Apparently this water pump fits in a counter bore making removal even more difficult. Some gasketed items have pry tabs cast into them, look carefully for them. The trick during a pry is to apply steady pressure at one point to break the seal then move to another point to continue tearing the seal. Any chance you will amend the title of this thread as it seems insufficient knowledge was the cause and not someone's prior repair? |

No sealant, very tight fit with dissimilar metals
In the housing, I hit the snout of the water pump in different spots pretty hard to break this loose:
And then there was some cavitation on the impeller, and the corrosion on the housing to clean up a bit:

Aaaarrghh! Why I dislike my ignorance and appreciate good mechanics.

Thanks for making the change.
Your original post was pretty tame but, this list is pretty hard on mechanics, repair shops and dealers, often for no good reason. The cries of "Sue ! , Sue ! " pepper posts for what they perceive as bad outcome due to malice, but when pressed for details or very specific questions are asked, they run for the shadows. |
