Kia Air Conditioning Compressor and Pump

Description

Installation Steps

1. 1. Safety & Preparation

   
   

   • Park on a flat surface, engage the parking brake, and disconnect the battery negative electrode (-).
     

   
   

   2. Remove the Old Compressor

   
   

   • Disconnect Components:
     • Detach the electrical connector from the compressor clutch.
     • Remove the drive belt using a belt tensioner tool.
     • Disconnect refrigerant lines (cap/open ends immediately to prevent debris/moisture ingress).
   • Unbolt the Compressor:
     • Remove mounting bolts securing the compressor to the engine bracket.
     • Note: If the compressor is seized, use penetrating oil to loosen bolts.

   
   

   3. Prepare the New Compressor

   
   

   • Drain Oil:
     • If replacing the compressor, drain and measure oil from the old unit. Subtract this volume from the manufacturer’s recommended oil capacity (e.g., 120cc for Rio/Forte) and drain the same amount from the new compressor via the suction port.
   • Replace O-Rings:
     • Install new R-134a-compatible O-rings on all refrigerant line fittings. Lubricate them with refrigerant oil to prevent damage during installation.

   
   

   4. Install the New Compressor

   
   

   • Align the new compressor with the mounting bracket.
   • Secure with bolts and torque ;22–33 N·m (14.8–24.3 lb-ft);(verify specs for your model/year).
   • Reconnect refrigerant lines and electrical connector.

   
   

   5. System Evacuation & Charging

   
   

   • Evacuate:
     • Use a vacuum pump to evacuate the system for at least 30 minutes to remove moisture/air.
   • Charge with Refrigerant:
     • Add the specified oil amount and refrigerant (R-134a or R-1234yf—check your vehicle’s label).
     • Total refrigerant charge;550 ±25g (19.4 oz);for most models.

   
   

   6. Test 

   
   

   • Start the engine, activate AC, and check for cold airflow.
