. SAVING YOUR AIR CONDITIONING REFRIGERANT If you have to remove the AIC compressor prior to remolling your engine, the. hoses must be disconn'ected. Fortunately, this . can be accomplished without ' losing all the refrigerant on earl ier .models equi pped with service valves. Unfortunately, service valves were phased out during the mid70s. The valves are in line with the hoses or lines and are usually covered with cadmium-plated caps. If yours is, remove the caps and run the valves in all the way. Close (turn clockwise) the high- and lowpressure valves at the compressor to isolate the charged system from the compressor. Remove the power-steering pump. You may When unbolting tne Alc compressor and its have t o disconnect the pump-to-reservoir return The system is now isolated from the commounting bracket from the engine, be ready t o line t o get it out of the way against the left handle about 25 pounds. pressor .

Now you so fluid doesn't run out_ can remove the hoses by disconnecting the service valves from the compressor ,so they stay with the -hoses and seal the system . Don't remove the valves from the hoses. Place the hoses oLit of the way and you're ready to remove the compressor after sealing it so it will stay clean and dry. Use the caps which are used to seal new compressors before they are installed. You should be able to pick some up for nothing at your local garage. Remove the compressor with its bracket and set it aside. A strong cord tied t o a bent nail supports the AIC compressor out of the way, subsequently avoiding the need for disconnecting compressor lines and recharging the AIC system. A rag keeps the nail from scratching the fender.
