Any aftermarket refrigerant additives (the ones you can buy at Wal-Mart, for example) come with the oil already in place. It is a synthetic oil - for this reason, it is incompatable with older refrigerants, which used mineral oils. A note of advice - if you don't know exactly what you are doing with the A/C system, take it to a professional, as you can really mess it up (overcharging the system, allowing impurities in, etc). If you cannot afford this, at least buy one of the more expensive refrigerant refills that have the guage calibrated to the temperature outside. Good luck!

There are several pulleys necessary for the A/C. The A/C clutch pulley on the AC compressor is one. If this is the one breaking, your compressor is not far behind. The resistance of the compressor is minimized by proper oil TYPE and proper quantity of oil and freon to keep the compressor bearings free. Now if you are talking about the tensioner pulley, both the AC clutch pulley and the tensioner can be too tight if the belt routing is wrong. On some engines the belt can be routed 2 ways. To save money, the belt could be looped to eliminate the AC, and another way to have a working AC. Could be the belt is installed wrong. There are different types of AC oils.
What kind of vehicle? It means have your ac inspected. On Toyotas, It is a fail-safe mechanism. The compressor speed and the engine speed are not in unison. So the magnetic clutch dissengages so the compressor doesn't lock down. This can be caused by the serpentine belt slipping, or the magnetic ac clutch relay in the fuse box, or the ac revolution sensor on the side of the compressor. It could also indicate that the compressor itself is going bad. More than likely it the revolution sensor going bad or it is low on compressor oil and freon
NEW AC COMPRESSOR POUR OUT SHIPPING OIL COME WITH IT ADD THEM SAME AMOUNT.IF YOU NOT SURE AND OIL BEEN POURED OUT.ADD 2 OUNCE R 134A REFRIGERANT OIL TO NEW COMPRESSOR. YOUR AC SYSTEM HOLD 1.75 LBS R 134A REFRIGERANT.
When replacing the compressor the dryer should also be replaced, you put 2oz of oil in compressor and stand compressor on pulley for 5 min, then after install turn clutch 10 turns to pump most oil out of compressor, the dryer should have 2 oz of oil also, if you are flushing the ac system out with a solvent then more oil is needed for the system, if your just replacing the compressor then 2oz in compressor.
If you have not cleaned out the ac system,the ac system will have oil in it,but,the compressor most likely does not have any in it,so pour about 4 to 5 oz in the low side opening on the compressor before installing it,and turn the center nut of the compressor clutch about 8 to 10 times,oil will try and come out the high side,when it does,this will be enough turning.If the system needs more oil,add as needed when freon is put in the system.If the oil is not added to the ac compressor before installing,the compressor could be damaged.Please rate if this was helpful,thank you.
doesnt mean system is empty,because no oil came out off compressor,unless the system was flush and should be flushed with cleaner, then the system would hold 10oz, of oil,also make sure to spin compressor by hand 10 times to get the oil and liqiud out of cylinders,add a couple ozes of oil in dryer then compressor and the evaporator core to equal 10oz of oil,after added oil to compressor stand on pulley to coat seal let sit for 10min, then after all line are connected then you spin 10 turns, hope this help,
There are a lot of variables with A/C concerns. Without being able to answer these, the smoke you saw was originating from the clutch? If so, can you see any kind of oil seeping from the seal behind it? You might also look for oil stains on the hood blanket above the compressor. If there is oil present, you may have a seal leaking causing premature clutch failure. Since you were in traffic at a stop, you might want to check the condensor and the radiator for any kind of obstruction. Also that the fan is coming on when the pressure starts to rise. If you have an oil leak it might be a good time to replace the compressor. If not, it could be just an early clutch and bearing failure. Also, don't forget to check the belt for overheat damage.
