'89 245 5 spd, 265k mi. I haven't used the AC in the 10 yrs I've owned it. Rt now the AC pulley turns a belt to turn the PS pump above the AC. I have an older style PS pump from a '83 parts car w projecting pulley to align w 3rd (outermost) groove on main-shaft pulley, thus by-passing the need for AC compressor.
What procedures to do to safely and completely remove 40 -50 lbs of never being used AC components?
What's involved to test the AC system to find out if it's a simple fix, or flush recharge to make it work? Any expected range of cost for that?

iPd used to sell a replacement puller for your current PS pump to by pass the AC pulley.

As for replacing it with an '83 PS pump, well, I dunno. There may be a different bracket, yet you would have hose position issues, maybe.

As for checking the AC, well, conversion kits to r134a are apparently not available anymore.

This board is replete with innumerable threads on revising AC systems and converting to r134a.

You could remove the compressor, the condenser coil in front of the engine coolant radiator, the drier, and the hoses back to the fire wall. Or you can get under the dash and disconnect the hoses from the evaporator coil.

To check for fault, you'd need to check system seal. I'd guess you have a leak someplace.

You may be able to kibble together the parts for working r134a conversion. Special o-ring, PAG oil, r134a cans.

Yet you really must pull all parts out of the car, including both coils. You have to throughly remove the old r12 refrigerant lubricant using a special type solvent detergent. Many do not do this adequately, and traces of the old and newer PAG ester 134a compatible lubricant may ruin or cause the compressor to seize.

You may have parts tested at an auto shop that does AC work to see if individual components work and seal. You may need replacement hoses constructed as r134a is a smaller molecule than is r12.

You you can reassemble, the compressor is clean and add some PAG ester oil, draw a vacuum using a refrigerant pump to check that your newly assembled system seals, it may work. It may help, if you can, to use a new AC clutch pulley. A over 26 year old AC compressor may be suspect at any rate.

Review the arciles using the search feature on this forum.

I'd like to do restore A/C to my 1991 using an r134a conversion, using the available kit, and replace the HVAC motor, all at once. No garage make that a real bother.

Hope that helps.

Thanks for so much detail, and relevant info. I'll locate an AC shop to consult further with.

I have an AC delete kit with new poly bushings if interested...

It is a Volvo factory bracket that remounts the stock PS pump, bypassing the double belt arrangement. Was put on cool weather cars in Canada, etc.

Hi MrNabisco!!!!

I finally found an example of the AC pulley bypass iPd offer, yet only for 83-84 240?

Yet also found this, which is probably what you have for the OP?

Thx, I got one of the IPD kits yrs ago for my '83 245 and it worked fine.
2nd pic looks about right for my '89 245.

Yep. That second kit is what I have, less the belt, but with new poly bushings. I got it for my 91, but it is for early models.

If anyone needs it let me know.

By early, do you mean 240s w the other style of PS pump?

I've got an '89 with bad compressor clutch bearings. Would this kit work? If so, how much for? Thanks.

Drop me an email and I'll send you pics. And we can talk price... Not expensive. It really depends upon which PS pump you have if the kit I have will work.

The pre-90 PS pump kits are not that rare. The later kits are hard to find.

To be clear, I am talking about AC compressor removal kits, not rebuild/reload.

I put new bushings in AC & PS mounting brackets and new belts, incl Alt. Now everything rolls smooth, aligned tight and quietly. That was hrs of work, but still simpler and quicker than Removing AC or swapping PS pump and hoses and fittings. Good for now!

Unless some other 'expurt' on this bored indicates otherwise, the kit for 1990 and before (to when) is no longer available. (NLA)

See my first reply in this thread. May be possible. $$$$$
