Installation Notes and Tips

Verify the vehicle uses the LTR4 compressor and R134a refrigerant before ordering. Replace the accumulator and orifice tube during compressor service, and flush the system as needed to remove debris from the failed component. Confirm the accumulator inlet and outlet fitting styles match the vehicle before installation. Use the specified PAG Oil /150 and follow the vehicle service procedure for evacuation and recharge.
