MAINTENANCE TIPS
Your vehicle’s air conditioning (AC) 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:
• 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
Your AC 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. Your AC 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 AC
System, follow these guidelines when servicing connections:
• 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
