#AUTO AC COMPRESSOR REPAIR HOW TO#

Then add as much new oil back into the compressor as you took out of the old compressor. Using a fresh measuring device, drain the oil from the new compressor following the steps above.

Step 3 Drain the oil from the new compressor Tilt the compressor back and forth several times while doing this to drain out as much oil as possible. Wait a few minutes for the remaining oil to drain down, then rotate the compressor shaft one-half turn every minute, for up to three minutes as you continue to drain and measure. Tilt the compressor to drain any oil from the suction and discharge ports. Remove the compressor crankcase drain plug and pour the oil into a measuring cup. Be careful not to spill any oil as you remove the compressor. Remove the retaining bolts and remove the compressor from the vehicle. Then disconnect the AC lines from the compressor. Step 2 Remove the old compressor, drain and measure If you overfill, youвЂ™ll dramatically reduce cooling. If you underfill, youвЂ™ll cause premature compressor piston/seal and valve failure. Skip this step and you risk under/overfilling the system with oil. Because youвЂ™ll have to add that same amount back into the system before you refill it. ItвЂ™s important to recover the refrigerant for environmental reasons, but itвЂ™s even more important to recover it to find out how much oil came out of the system. ItвЂ™s illegal to vent refrigerant into the atmosphere, so you should pay a shop to evacuate, recover, and measure how much oil came out. Step 1 Evacuate any remaining refrigerant and measure how much oil came out with it. The oil in the compressor crankcase lubricates the metal moving parts, while the oil in the system is carried by the refrigerant to lubricate the compressorвЂ™s pistons and valves. ThereвЂ™s oil inside the compressor crankcase and oil throughout the AC system.

You can replace an auto AC compressor yourself as long as you make sure youвЂ™ve added the correct amount of oil. If the AC compressor has failed on your vehicle and you want to replace it yourself, here are some tips from the pros.
