Warranty returns are subject to inspection in our factory prior to acceptance and approval. Warranty returns will not be accepted on any compressor unless these parts are replaced and the A/C system is serviced as follows:

1. Flush the evaporator, condenser and lines with a chemical flush approved for Auto A/C before installing new compressor and drier.
2. Replace accumulator/receiver drier. Failure to do this vacates our warranty.
3. Replace orifice tube or check expansion valve for contamination.
4. The A/C system must be flushed or an inline filter must be installed. Flushing must include condenser and evaporator. IMPORTANT-Compressors contaminated with black oil or any foreign material will not be warranted.
5. When replacing a Ford built FX15 or FS10 compressor that has suffered a catastrophic failure, the condenser must be flushed or replaced. If the discharge hose assembly is equipped with a muffler, the hose assembly Must be replaced.
6. The proper amount and type of lubricant for the system must be added. After installation, rotate the compressor shaft to ensure no liquid remains in the cylinders. This will lubricate all internal compressor components.
7. Charge the system with the proper amount and type refrigerant( R12 or R134A only).

The following steps are highly recommended to ensure effective operation and performance.

1. Check operation of engine-driven fan clutch or electric radiator and condenser fan motor.
2. Check operation of clutch cycling switch or relay and all safety switches.
3. Check for proper operation of cooling system.
4. Check the external condition of the condenser (bent fins, road debris and leaks).
5. Check all drive belts and pulleys for alignment and wear.
6. Inspect Schrader valves and sealing caps. If retrofitting, install proper retrofit fittings.
7. Inspect all hoses and fittings for leaks and repair as necessary.
8. Evacuate system to 29.5 in. HG for 1 hour. The system must hold the vacuum steady for 20 minutes before charging.
                If the vacuum is not held steady for 20 minutes, the system must be rechecked for possible leaks to be corrected.
9. After charging the system, leak test and performance test the system.
