[QUOTE="vantageX, post: 1298867, member: 28293"] Ok, long post coming up so beware...then again all my posts are long...lol Your compressor has a clutch, if this clutch fails or is going to fail then chances are at low RPM your compressor will not be running at its full capacity. There aren't many ways to overcome this other than to change the compressor or get somebody to open the compressor up and rebuild it to original specifications. Another thing, most compressors if not all (not sure if all) have an oil refill plug. Most competant air-cond technicians will refill or at least check the level of oil in a compressor when doing a full service. This oil usually lubricates the internal bearings and basically keeps your compressor running quietly and efficiently. Usually this oil will not require topping up unless you're changing a big component like the cooling coil or something else. But there's no harm in checking and the oil level in 2nd hand compressors should be checked. As for refrigerant. R12 refrigerant or gas was banned in the US during the mid-90s. Manufacturers were required to switch to R22 or R132. R12 was phased out slowly and is almost impossible to acquire now. A car equipped with an R12 system has to be converted to accept R22 or R132. R134/132 is less efficient than R12 in terms of energy needed to provide coolness but is more friendly to the environment if compared to R12. We still get R12 over here though cause well, we don't care about the environment... :D I'm not too sure if an R132 equipped car will be able to run on R12 but I don't see it being a problem because we have a lot of new cars over here running R132 systems and if they are being refilled by our local air-cond boys and no complaints have been registered as of yet then it should be ok to run R12 in an R132 equipped car...I think... Oh but an R12 equipped car cannot run R132 or R22 gas. I'm very sure of that! [/QUOTE]
