WARNING: Cancer and Reproductive Harm - www.P65Warnings.ca.govWhen replacing your compressor, it is very important to use suction screens and inline filters on liquid lines. These filters and screens will catch any debris in the system to avoid damage to the new compressor. ACDelco also recommends system flushing using native refrigerant before installing a new compressor.
- Musty smell when the air conditioning or heating system is activated
- Inadequate cooling or heating temperatures when using the air conditioning or heating system
- The vehicle’s temperature gauge indicates a ‘red’ condition
- Steam coming from the engine compartment
- Unusual smells inside or outside the vehicle
- Use the proper O-ring for the system
- Thoroughly clean all fittings and do not over torque beyond what is recommended
- Always lubricate O-rings with clean refrigerant oil
- Always replace sealing caps on service ports
- Recover refrigerant from the system when or if necessary
- Keep dirt and foreign material from all sealing surfaces
Your A/C system must be maintained with the correct level of refrigerant and appropriate pressure to work properly. An A/C system leak, which could result in incorrect fluid or pressure levels, could potentially harm or interfere with the performance of your A/C system. This would result in lack of or insufficient cooling performance. Common causes of A/C system leaks include:
- Reduced cooling capacity in your vehicle’s cabin
- Evidence of physical damage to the condenser
- Fittings or tubes saturated with compressor oil
- Signs of corrosion in the system
- Leaking vanes or tanks
- Debris clogged core
- Plugged internal passages
- Worn or damaged service valves and caps
- Worn hoses
- Loose connections
- Seal failures
- Damaged components
- Damaged evaporator
- Damaged condenser
- A/C system component corrosion
