okay so my power steering pump leaked onto my ac compressor and seized up the pulley so i took off the p/s belt and the a/c belt. and now that summers coming i want to run ac again and just got another compressor. can i just unbolt the compressor and hoses and reconnect them to the new one?

 

You need to have the refrigerant recovered first. You might be able to get a shop to recover it, the let you go change the compressor, and then vacuum/recharge the system the same day for the cost of 1 AC service.

It might just be the compressor clutch or a corroded connection. In that case you should be able to repair it without disconnecting any lines and opening the system. If you do disconnect lines to replace the compressor, make sure you use new o-rings.

 

Ditto the above, mostly.

You will have to have a "recovery" done before you can swap out the compressor.

I also agree the problem is the clutch assembly that is the problem, not the compressor itself.

I disagree that it can be repaired without removing it, I guess it is possible if someone has a puller short enough for the clearance you have.

I would check around for an A/C shop that would do the recovery for free, we would if we knew you would be coming back for the recharge.

As mentioned, replace the O rings, no matter how good they look, make sure the connections are clean, VERY CLEAN, a small speck of dirt on an O ring will lead to a leak, lube up the O rings with C4 oil or you can use Ester oil, you can even use the oil out of the compressor, [if it's clean] do not try and install lines with dry O rings, it can result in leaks and/or damage to the O rings.

You will also have to "check the oil", empty the all the oil from your compressor into a measuring cup, empty the oil if any in the compressor you got, [unless it is a new/remand with "packing oil" only] put the same amount of oil you drained from the old compressor into the new compressor, use Ester oil, it is compatible with all A/C systems.

If you do not want to do the oil, note the amount you removed from your compressor and have the A/C shop inject it during the recharge. 94

 

ohh okay. thanks guys. thought this was gonna be an easy fix, but looks like im gonna have to take it somewhere either way.

 

so i just neeed to get the refrigerant recovered then i could recharge it myself?

 

No, unless you have access to an AC machine that will pull a vacuum to get all the moisture out before recharging. Those DIY cans suck. You need no moisture and the proper amount of refrigerant for the AC to perform well.

 

ohhh alrite. my friend said that when he changed his he pulled the hose off and just let the refrigerant leak out then reconnected it and used that recharge can -____-

 

bummpppp....technically can i just pull off the hoses? or will that create unwanted moisture?

 

Besides being illegal, a "catastrophic" discharge, [like pulling a line] will also dump oil, a low oil charge will lead to improper cooling and compressor failure.

If your looking to save money, have the system properly recovered, install the new compressor yourself, have it properly charged at an A/C shop.

The "recharge can" will contain sealers, they are not good for the system, they also contain hydrocarbons that will contaminate the system, also not a good thing.94

do it right and you will come out ahead of the game in the end.
