Introduction
The UAC KT 2037A A/C Compressor and Component Kit is a comprehensive solution designed for aftermarket air conditioning system replacement. This kit includes all necessary components to restore your vehicle's air conditioning functionality to optimal performance. UAC parts are manufactured and rigorously tested to meet or exceed original equipment (OE) specifications, ensuring reliability and a precise fit.
Components Included
The UAC KT 2037A kit comes complete with the following essential components:
- 7SBU16C Compressor Assembly: The core component responsible for circulating refrigerant.
- Block Expansion Valve: Regulates the flow of refrigerant into the evaporator.
- Rapid Seal Oring Kit: A complete set of O-rings for sealing connections and preventing leaks.
- PAG 46 (R-134a) Oil: The specific lubricant required for the A/C system using R-134a refrigerant.
- Condenser Parallel Flow: Dissipates heat from the refrigerant, converting it from a gas to a liquid.

Setup and Installation
Installation of an A/C compressor and component kit requires specialized tools and knowledge of automotive air conditioning systems. It is highly recommended that installation be performed by a certified professional to ensure proper function, prevent damage to components, and comply with environmental regulations regarding refrigerant handling.
Pre-Installation Checks:
- Vehicle Compatibility: Confirm that this kit (UAC KT 2037A) is compatible with your specific vehicle's year, make, and model. Refer to your vehicle's service manual or use online compatibility tools.
- System Flush: It is crucial to thoroughly flush the entire A/C system to remove any contaminants, debris, or old oil from previous component failures. Failure to do so can lead to premature failure of the new compressor.
- Refrigerant Type: Ensure your vehicle uses R-134a refrigerant, as the included PAG 46 oil is specifically for R-134a systems.
- Component Inspection: Inspect all new components for any shipping damage before beginning installation.
Installation Steps (General Overview):
- Safely discharge the existing A/C system refrigerant using proper recovery equipment.
- Remove old components (compressor, condenser, expansion valve, etc.).
- Thoroughly flush the A/C lines, evaporator, and any other reusable components.
- Install the new condenser, ensuring proper mounting and connections.
- Install the new expansion valve.
- Install the new compressor, ensuring proper alignment and belt tension. Add the specified amount of PAG 46 oil to the compressor and system as per vehicle manufacturer specifications.
- Replace all O-rings with the new ones provided in the kit at every connection point.
- Evacuate the A/C system using a vacuum pump to remove air and moisture. Maintain vacuum for at least 30-45 minutes to ensure complete dehydration.
- Recharge the system with the correct amount of R-134a refrigerant according to vehicle manufacturer specifications.
- Perform leak detection and system performance tests.
Operating Instructions
Once the UAC KT 2037A A/C Compressor and Component Kit is professionally installed and the system is properly charged, the operation of your vehicle's air conditioning system will function as designed by the vehicle manufacturer. There are no specific operating instructions for the kit itself, as it integrates into your vehicle's existing A/C system controls.
To operate your vehicle's A/C system:
- Turn on your vehicle's engine.
- Locate the A/C controls on your dashboard (typically a button labeled "A/C" or a snowflake icon).
- Press the A/C button to engage the compressor.
- Adjust the temperature and fan speed settings to your desired comfort level.
- For optimal cooling, ensure windows are closed and the recirculation mode is engaged.
Maintenance
Proper maintenance of your vehicle's A/C system, especially after installing new components, can significantly extend its lifespan and ensure efficient operation.
- Regular Use: Run your A/C system for at least 10-15 minutes once a week, even in cold weather. This circulates the refrigerant and oil, keeping seals lubricated and preventing component degradation.
- Cabin Air Filter: Regularly check and replace your cabin air filter. A clogged filter restricts airflow, reduces cooling efficiency, and can strain the system.
- Condenser Cleaning: Keep the condenser (located in front of the radiator) free of debris like leaves, dirt, and bugs. A dirty condenser cannot efficiently dissipate heat, reducing cooling performance.
- Belt Inspection: Periodically check the serpentine belt that drives the compressor for cracks, fraying, or excessive wear. Replace if necessary.
- Professional Inspection: Have your A/C system professionally inspected annually. A technician can check refrigerant levels, inspect for leaks, and assess overall system health.
Troubleshooting
If you experience issues with your A/C system after installing the UAC KT 2037A kit, consider the following common problems and potential solutions. For complex issues, consult a qualified automotive technician.
| Problem | Possible Cause | Solution |
|---|---|---|
| A/C Not Blowing Cold Air | Low refrigerant charge, clogged condenser, faulty expansion valve, compressor not engaging, electrical issue. | Check for leaks, ensure proper refrigerant level. Clean condenser. Inspect electrical connections to compressor. Professional diagnosis recommended. |
| Weak Airflow | Clogged cabin air filter, blocked vents, faulty blower motor. | Replace cabin air filter. Check for obstructions in vents. Inspect blower motor and resistor. |
| Unusual Noises from A/C | Compressor bearing failure, loose mounting, low refrigerant (causing compressor strain), worn belt. | Have compressor inspected. Check mounting bolts. Verify refrigerant charge. Inspect and replace belt if worn. |
| A/C Cycles On and Off Frequently | Low refrigerant, overcharged system, faulty pressure switch, clogged orifice tube/expansion valve. | Check refrigerant levels. Ensure proper charge. Inspect pressure switches. Professional diagnosis for internal blockages. |
