THE SERVICE A/C COMPRESSOR DOES NOT MOUNT EASILY TO THE VEHICLE DUE TO THE BODY OF THE COMPRESSOR INTERFERING WITH THE WATER PUMP BRACKET. THIS MAKES IT DIFFICULT TO ALIGN AND ATTACH THE BOLTS.

THE SERVICE A/C COMPRESSOR HAS BEEN REDESIGNED WITH ADDITIONAL RIBS WHICH FURTHER INCREASES THE DIFFICULTY OF INSTALLING A SERVICE A/C COMPRESSOR.
