Changing a/c compression pump
Removal of belt is necessary, untension as necessary and remove, may need to remove other components for access, remove and verify with new compressor that has a/c oil in it and replace seals/gaskets, will want to change orifice tube and accumulator, compressor manufacturer will not warranty without accum replacement, again verify correct amount of needed oil in system and make sure system is full to correct amount, will need to evacuate and recharge with proper amount of refrigerant. There should be a sticker near the evap housing with correct amount. This may be beyond you if never done before and do not have correct tools. If so use this site:
