Please refer to Section 1 for all Charging and Discharging procedures.

It may be illegal in certain areas to service air conditioning components unless you are certified and have an approved recovery/recycling station. Consult with your local authorities.

Removing the condenser is not usually a difficult job, although some bolts may be hard to access. Some do-it-yourself mechanics may encounter air conditioning troubles after the condenser is reinstalled if the system fails to work properly. Remember some simple rules to avoid air conditioning problems.

Dirt and moisture are the enemy. Any line which is disconnected should be immediately plugged or capped with a tight-fitting seal.
Handle lines and hoses carefully; any bend or kink reduces system capacity. Never attempt to straighten a bent line-replace it.
If the line fitting has two wrench fittings, counterhold one while turning the other. The lines are lightweight metal and bend easily.
Even though the system is discharged, loosen fittings slowly and listen for any remaining pressure; allow it to bleed slowly before removing the line.
Most line joints or fittings contain a small rubber O-ring. Always replace it before rejoining the lines. Make sure the new O-ring is free of nicks or scratches.
Fittings must be reconnected carefully and tightened to the correct torque. Too tight damages threads, too loose will leak.


The compressed refrigerant used in the air conditioning system expands into the atmosphere at a temperature of -21.7F (-29.8C) or lower.

This will freeze any surface, including your eyes, that it contacts. In addition, the refrigerant decomposes into a poisonous gas in the presence of a flame. Do not open or disconnect any part of the air conditioning system until you have read the SAFETY WARNINGS information.
