How to remove an A/C Compressor on Pontiac G5?

To remove the air conditioning system, start by discharging and recovering the system. Then, disconnect the battery cable and loosen the lug nuts on the right front wheel. Raise the vehicle and support it securely on jackstands before removing the wheel. Remove the inner fender splash shield and the drivebelt. For 2.0L supercharged models, drain the intercooler cooling system and remove the bolts securing the intercooler water pump. Disconnect the electrical connector from the compressor clutch field coil and, if necessary, the high-pressure sensor electrical connector. Disconnect the compressor inlet and outlet lines, removing the old O-rings. Finally, remove the compressor by taking out the mounting bolts. To install a new compressor, follow the manufacturer's instructions for measuring and adding new oil. The clutch may need to be transferred from the original compressor. Before reconnecting the inlet and outlet lines, replace the manifold O-rings and lubricate them with refrigerant oil. Then, reverse the removal steps. Once installed, have the system evacuated, recharged, and leak tested by a professional.

Pontiac G5 A/C Compressor

The Pontiac G5 A/C Compressor works by forcing a low pressure refrigerant gas to become a high pressure high temperature gas. This allows the system to expel heat before the refrigerant cools off and continues to receive heat from the passenger cabin. The A/C Compressor inside every G5 is the highly important part of the air conditioning loop, pumping the refrigerant through the condenser, evaporator and back again to ensure that temperature control never goes awry on a hot day. Over the years, Pontiac relied on two main refrigerant standards, R12 units and R134a designs, but the operating principle of the A/C Compressor stayed the same. The refrigerant is turned from gas to liquid and back again through pressure changes to create a repeatable cycle. The R12 versions work with a mineral oil but the R134a version uses a different lubricant so the two cannot be interchanged without converting the system. Each A/C Compressor in the compact G5 line features durable internal valves and a belt driven clutch that only engages when cooling is demanded to enhance fuel efficiency and help reduce wear. When the airflow becomes weak, the very first component that they will always check is the A/C Compressor. Thus, it gives Pontiac drivers a head start on their diagnosis.

Each OEM Pontiac G5 A/C Compressor we offer is competitively priced and comes with the assurance of the manufacturer's warranty for the part. Furthermore, we guarantee the speedy delivery of your orders right to your doorstep. Our hassle-free return policy is also in place for your peace of mind.
