Removing water pump w/AC

[GOLDMYN]

Hi, I'm trying (using that word loosely) to get a cross-threaded after-market temp gauge pipe which the previous owner installed. The water pump housing needs to come off but my AC has a charge and of-course I can't getget

at the bolts, I didn't want to waste that if possible. any ideas will be appreciated PS I have used heat and koil with no results

I would try drilling a hole across and thru the pipe nipple, then stick a stout drift punch in the hole to see if nipple will move, I suspect if you can break it loose it will come out. A 1/2" pipe extractor would be another option. (Ace Hardware)

Failing that, the compressor can be detached from the housing without losing the charge. First remove the belts. There is a bolt in the center of the clutch assembly, remove that bolt. The clutch assembly is on a tapered shaft so some gentle tapping with a wood block should pop it loose so it can be removed and gotten out of the way. Once that is done you can unbolt the bracket at the front of the compressor. Remove the rest of the compressor brackets and the power steering pump. The compressor is mounted on flex hoses and it will now be possible to lift it up enough to clear the housing. This would be an excellent time to replace the timing chain if that has not already been done. Be sure to replace the cover gasket and the hub seal.

thanks for your response

You need to remove the AC clutch assembly. This may require the use of a specialized tool if it’s on tight. Remove the retaining bolt from the clutch and see if you can carefully pry it off, I have used two large screwdrivers on either side to pop it. Whatever you do don’t force it as it will get damaged. Then you can get access to the pump.

I once borrowed one of these for the heater nipples. A lifesaver!!!

You will also need to remove the lower pulleys and the harmonic balancer to get them out of the way to access the rest of the bolts in the housing. You will need a puller to get the unit off of the crankshaft. This would be an excellent time to replace the timing chain if that has not already been done. Be sure to replace the cover gasket and the hub seal.

That's a big block. No need to pull the damper.

Get the compressor out of the way and have at it. Also I don't see the reason for disturbing the clutch. Looks like you could just lift the compressor, brackets and all up out of the way.

You are correct, I generally always do the chain if I get that far into one. Corrected post above.

success, we were able to extract the spacer. it was a combinations of a neighbor with a better set of vise grips and more muscle than this old(71) Marine.
