Question about 2002 Chevrolet Silverado 1500
It's not that hard to do, but your going to need the proper equipment to do the job. You need to evacuate the a/c system before you remove the compressor. If you have done that, the compressor is held on by i believe two bolts on the a/c mount. First remove the serpentine belt and then the high and low pressure line from the compressor, un clip the a/c clutch wire harness and then remove the bolts that hold the compressor to the a/c mount. Replace the compressor and use lock tight. Before you install the a/c lines, make sure your have new O rings and oil them before installing the lines back. Clip the a/c clutch harness and place the serpentine belt back on. Note it's a good time to change the a/c accumulator ( receiver-drier). At this point the system is going to need to be vacuumed out before refilling, rule used is if the system has less then 10psi. It needs to be vacuumed out before recharging due to moisture will be present in the system and will cause icing on the low side resulting in poor a/c performance. The low side should be 35psi to 50 psi and the high side should be 150psi to 200psi. If the readings are not with in those numbers, a/c performance will be poor. If you do not have the proper equipment and want to save some money, may be you can just do the replacement of the compressor and have a professional shop vacuum out the system and recharge it. If there is a leak your going to have them do it all over again and find the leak. If they install and there is a leak in the system, your just going to have to bring it back and the job will be covered under warranty. Good luck and hope this helps. Keep me posted, be glad to help and answer any questions.
