How to remove the A/C Compressor on Cadillac CTS?

To remove the air conditioning system, start by discharging the system and disconnecting the negative battery terminal. Then, raise the vehicle and remove the lower and inner fender splash shields. Next, remove the drivebelt and the air filter housing with the inlet air resonator. Disconnect the electrical connector from the compressor clutch field coil. Remove the compressor inlet and outlet line mounting bolts, discard the old O-rings, and remove the lines from the compressor. Finally, remove the compressor by taking out the mounting bolts. For installation, follow the instructions provided with the new compressor, drain excess oil if necessary, and transfer the clutch if needed. Replace all O-rings and lubricate them with refrigerant oil before reconnecting the lines to the compressor. Reinstall all the components in the reverse order of removal. Finally, have the system evacuated, recharged, and leak tested.

Cadillac CTS A/C Compressor

The Cadillac CTS A/C Compressor is the main part of the cabin cooling system that converts warm low-pressure refrigerant gas into a high-pressure hot gas that begins the process. Once the A/C Compressor increases the pressure and temperature, the hot refrigerant enters the condenser. There, outside airflow draws heat away from the refrigerant. This allows the cool liquid to leave and enter the evaporator. The refrigerant releases cool air into the cabin area, repeating the cycle in a closed loop. Over the model years, the basic positive-displacement design of the A/C Compressor has remained the same, but the different model units have been manufactured by the OEMs to suit either an R12 charge or a R134a charge. This is an important difference as each will require a specific lubricant. Later CTS versions have all switched to R134a as the standard refrigerant. Therefore, owners of Cadillac sedans built before the full switch should check what refrigerant their car uses. It's important to do this before they place an order for a replacement A/C Compressor. A healthy A/C Compressor does ensure reliable temperature control regardless of the generation. Thus, with every CTS ride more comfortable at the peak of summer heat, the premium atmosphere you expect also gets kept thanks to the engineering of Cadillac.

Each OEM Cadillac CTS 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.
