Suggestions Appreciated

Year: 1977
Make: Ford
Engine Size: 351c.i.

I inherited my father's 1977 Ford F-100 Ranger. Before he finally gave up driving he had one last fender bender (rear ended a gravel truck in foggy weather).

He never used the air conditioner so didn't bother to repair it after the accident; when I tried to use it - no go. I had the condenser and accumulator-drier replaced and all was well for a few months. Took it back to the shop - "Oh - your compressor is bad".

I intend to flush the condenser, evaporator, and hoses (new hoses when the condenser was replaced). I will replace the compressor, accumulator-drier, and expansion valve. While I am at it I will also replace the clutch brushes, evaporator switch. blower motor, and motor switch. I also own a 1988 Bronco which uses 134a so I am going to convert the F-100 to 134a.

Other than a clutch puller and flusher, during the past six months I purchased some tools and equipment I need to do the job myself: vacuum pump, gauges, digital and analog thermometers. refrigerant scale, and 30# of Dupont 134a (got a good deal on sale). In the mean time I have successfully completed major AC repairs on a couple of farm tractors; I am confident I can tackle my own job now Pulling the evaporator and replacing the blower motor in this pickup is a major job so I want to do this right.


1. Am I on the right track with component flushing and replacement parts?
2. Would I be better off with a new compressor or a rebuilt one?
3. Even though the clutch is 32 years old, it has not been used much. OK to replace brushes or should I buy a new compressor w/clutch?

Thanks in advance for any suggestions.

1. You are but to get the best efficiency you will want to replace the O.E.M. style condenser with a parallel flow one if switching to R134a.
2. If you are going to do the whole system and go through the trouble or replacing and flushing it all I would recommend a new one. Your truck should have a York compressor. Depending if it is LHS (Left Hand Suction) or RHS (Right Hand Suction) there are a lot of options available. There are even Generic new York's that can be had for the price or a rebuilt compressor. If it were me. I would recommend switching to a universal Seltec compressor. We offer a mount with compressor to take your York setup to a universal Seltec one. Very minimal modification if any would be needed.
3. This would be solved by purchasing the York to Seltec conversion. In either case, even if you stick with the York I would recommend getting a new clutch with the compressor.

If you have any other advice feel free to email me.
