I read that there was a conversion kit by Honda part #38020-SM4-A1AH. When I ran the part# on my favorite Honda Parts source it showed this.

ACCORD'88 - '89, CIVIC'90 - '93, PRELUDE'90 - '93

I have a 1992 Accord LX Wagon. Will this kit cross to a 1992 Accord? I plan on buying a new compressor, reciever/dryer and anything else necessary. I plan on installing the parts myself then taking it to a shop for full flush and charge. Any suggestions would be greatly appreciated. I live in So Cal and it gets blasted hot in the summer.

 

I've move this to the proper section.

 

If your compressor was working w/ R12 it will work w/ R134a.

You will need a new receiver/drier and adapter fittings for high and low AC pressure connections. I would want to know what was in the kit, but based on price I would guess that only above components are included.

If you plan to keep the car and enjoy, I would recommend removing the evaporator, cleaning the evap cabinet, and replacing orings on the expansion valve (some replace the expansion valve as R134a works best w/ slighlty lower pressures in evaporator) and pressure feedback bulb. Old orings are almost certain to be leaking, so every oring in system should be replaced.

Suggest also air blasting the condensor and hoses (hold finger over outlet, pressurize inlet w/ rubber tip air gun, allow pressure to build, and release0 to remove old R12 lubricant. Remove compressor and drain, even if you plan to re-use.

You will need an ac manifold gauge set and a vacuum pump to prepare for charging. See autoacforum.com for guidance on correct charging procedure.

good luck

 

Sorry about, that I haven't posted here very often and not real sure where stuff goes.

 

I wanted to change out the parts myself, then have a pro flush and charge. I have had some experience. My Dad had a 1980 Chevy LUV (Isuzu) with no A/C which was only available as a dealer install kit. Found a junk yard truck w/ the kit. I took all but the compressor and dryer. The kit compressors were no longer available. I took the mounting bracket from an '81 Isuzu Pup, it bolted right up to the G-180 in the LUV and the compressors were still available. A pro flushed and gased the system which blew Ice Cold for many years.

Any hints where to start parts collecting the R-134 stuff I need? Thanks in advance!

I don't know what is in that conversion kit, but I would guess that it should work for your car.

You would need the fittings for the high and low ports on the line, a new receiver/dryer, new o-rings throughout the whole system. You may want to install a new expansion valve.

Right now, there is an auction on ebay telling what you get in that kit. Just search the OEM honda part number on ebay and you will see it.

 

Another possible source for conversion parts is ackits.com. I have used them and found their parts to be quality parts.

good luck
