| Good Maintenance Practices - Section 1 - Bullet 1 | Musty smell when the air conditioning or heating system is activated |
| Good Maintenance Practices - Section 1 - Bullet 2 | Inadequate cooling or heating temperatures when using the air conditioning or heating system |
| Good Maintenance Practices - Section 1 - Bullet 3 | The vehicle's temperature gauge indicates a 'red' condition |
| Good Maintenance Practices - Section 1 - Bullet 4 | Steam coming from the engine compartment |
| Good Maintenance Practices - Section 1 - Bullet 5 | Unusual smells inside or outside the vehicle |
| Good Maintenance Practices - Section 1 - Header | Your vehicle's air conditioning (A/C) system should be routinely checked by a professional technician. This should occur approximately every 12 months, though you should check your owner's manual for more specific recommendations. Any related maintenance should be handled only by professionals. If you notice any of the following conditions, have your vehicle checked right away: |
| Good Maintenance Practices - Section 2 - Header | Your A/C system requires proper air flow to operate effectively. Poor air flow across the condenser will impact system performance and can increase refrigerant system pressure. Make sure air flow into your system is not obstructed by bugs, leaves, dirt, or other contaminates in between tune ups. |
| Good Maintenance Practices - Section 3 - Bullet 1 | Use the proper O-ring for the system |
| Good Maintenance Practices - Section 3 - Bullet 2 | Thoroughly clean all fittings and do not over torque beyond what is recommended |
| Good Maintenance Practices - Section 3 - Bullet 3 | Always lubricate O-rings with clean refrigerant oil |
| Good Maintenance Practices - Section 3 - Bullet 4 | Always replace sealing caps on service ports |
| Good Maintenance Practices - Section 3 - Bullet 5 | Recover refrigerant from the system when or if necessary |
| Good Maintenance Practices - Section 3 - Bullet 6 | Keep dirt and foreign material from all sealing surfaces |
| Good Maintenance Practices - Section 3 - Header | Your A/C system is a sealed system, which includes different components connected by hoses, tubes, or lines. To keep the system leak free, inlet and outlet fittings have O-rings or seal washers, and the lines have leak free fittings. To help prevent leaks in the A/C System, follow these guidelines when servicing connections: |
| Good Maintenance Practices - Section 4 - Header | When 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. |

| Signs of Wear & Troubleshooting - Section 1 - Bullet 1 | Internal compressor fault |
| Signs of Wear & Troubleshooting - Section 1 - Bullet 2 | A/C clutch or electrical circuit failure |
| Signs of Wear & Troubleshooting - Section 1 - Bullet 3 | A broken or loose drive belt |
| Signs of Wear & Troubleshooting - Section 1 - Header | Lack of or insufficient cooling, excessive clicking sounds, unusual noises, or growling when using the A/C system could be a sign of a worn A/C compressor or components. This could be due to: |
| Signs of Wear & Troubleshooting - Section 2 - Bullet 1 | Worn or damaged service valves and caps |
| Signs of Wear & Troubleshooting - Section 2 - Bullet 10 | A/C system component corrosion |
| Signs of Wear & Troubleshooting - Section 2 - Bullet 11 | Missing service cap |
| Signs of Wear & Troubleshooting - Section 2 - Bullet 2 | Worn hoses |
| Signs of Wear & Troubleshooting - Section 2 - Bullet 3 | Loose connections |
| Signs of Wear & Troubleshooting - Section 2 - Bullet 4 | Seal failures |
| Signs of Wear & Troubleshooting - Section 2 - Bullet 5 | Damaged components |
| Signs of Wear & Troubleshooting - Section 2 - Bullet 6 | Worn or damaged compressor shaft seal |

| Signs of Wear & Troubleshooting - Section 2 - Bullet 8 | Worn or damaged condenser |
| Signs of Wear & Troubleshooting - Section 2 - Bullet 9 | Worn or damaged compressor seals |
| Signs of Wear & Troubleshooting - Section 2 - Header | 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: |
| Signs of Wear & Troubleshooting - Section 3 - Bullet 1 | Use a leak detection dye, such as ACDelco Fluorescent Tracer Dye. Be sure to use the dye that is specified for use with your systems oil and refrigerant type. |
| Signs of Wear & Troubleshooting - Section 3 - Bullet 2 | Look for dirt or containment build up around hose or line connections. This could be a sign that oil, which would attract and hold contaminants, is leaking out of the connection. |
| Signs of Wear & Troubleshooting - Section 3 - Header | To check your A/C system for leaks: |
| Switch Service Port | No |
