Recharge Air Conditioning with Freon in a Pontiac Bonneville

Recharge Air Conditioning with Freon in a Pontiac Bonneville - Inspect the air conditioning system for leaks. If your Bonneville is R134 compatible, you can use a leak detection kit from your local automotive store. Some of these kits will seal small leaks.Figure out if your car uses R134 or R12 refrigerant. To do this, find the Low Pressure Side service port on the larger line coming from the compressor. The location will vary with different year models and engines. It has a black cap on it. Remove this cap and look at the connector. You will notice screw type connectors in models using R12 refrigerant. They R134 compatible systems have a quick connect valve on the Low Pressure Side. Models made in or before 1995 may use the old R12 refrigerant. If this is the case, you must have your Bonneville's air conditioning system retrofitted to use R134 refrigerant.

Check your air conditioning system pressure using an automotive air conditioning pressure gauge. Keep in mind that in order to get an accurate reading, the air conditioner has to be turned on the coldest setting with maximum blowing power.

Connect the refill hose to the connector on the Low Pressure Side of the air conditioning system according to the instructions included in the kit. Make sure that it is securely attached.

Allow the air conditioner to pull the refrigerant out of the can by slowly turning the valve on the refill kit hose until it is fully open. Pay attention to the way you hold the can. Most kits will have you hold the can upright when you recharge the air conditioning system. It may take as long as 10 minutes to empty a single can.

An air conditioner that is blowing warm air is frustrating. If all of the components are working properly in your Bonneville, you may need to recharge your system with refrigerant. Recharging the air conditioner yourself in your Bonneville is possible if your car is R134 compatible. Most models made in 1995 or prior to that use R12 refrigerant. - by eHow
