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

To work on vehicles made in 2006 or later, first get rid of the old air conditioning refrigerant, then disconnect the black cable from the battery's negative terminal. Stand on the parking brake, make the back tires immovable, then lift the front of the vehicle just level with sturdy jackstands. Take off the drivebelt, remove the right front wheel, and pull away all plastic factory covers that are below and around the compressor so you can work more easily. Then take off the engine splash guard below and oil filter from under the engine bay. Seal off both end connections of your refrigerant hoses from the compressor, then block all other possible entry points with plugs to keep dust and moisture out. Unscrew the washer fluid container and detach the compressor from its mount to pull it free from the wheel area. Connect the clutch from the old compressor to the new one if needed, needing special tools to do this. Put in the right amount of oil for the new compressor, using numbers from your measurements of the old compressor's oil levels. Set up is the same as taking it apart, except you use fresh rubber gaskets and grease the rubber with clean engine oil. Then make sure the flat gaskets sit straight and stay oil free. Finish job by draining out air, refilling the system with enough refrigerant, and checking for leaks.

Cadillac DTS A/C Compressor

The Cadillac DTS A/C Compressor makes the sedan's climate system operate through pressure. Thanks to this component, lukewarm air from inside the cabin gets cooled down. This allows for a refreshing and cool breeze during long hot drives. The inlet inside the spacious cabin of the DTS withdraws low-pressure refrigerant gas, which is then compressed into a high-pressure high-temperature state. The hot vapor is propelled straight towards the condenser where outside air removes the heat. After cooling, refrigerant arrives at the evaporator. The liquid expands back to gas, absorbing warmth from the cabin. Cool air floods the car vents and the loop restarts. The earlier models employed R12 refrigerant systems whereas the later models incorporated R134a refrigerant systems. It is this change that distinguishes the difference between the styles of compressor. This is because the mineral oil that is applied in R12 will not protect units that are designed for R134a. An original Cadillac unit will guarantee a proper fit and seal for the A/C Compressor. Cabin temperatures climb quickly if the A/C Compressor fails. Choosing the right A/C Compressor, therefore, depends on knowing which refrigerant the specific car uses and the exact part number as listed for the vehicle. The healthy A/C Compressor provides precise interior temperature control, keeps passengers comfortable, and maintains a level of refinement expected of all Cadillac drivers of the enduring DTS nameplate.

Each OEM Cadillac DTS A/C Compressor we offer is competitively priced and comes with the assurance of the manufacturer's warranty for the part.
