Car Air Conditioning Maintenance: Ford Mustang


Has the air conditioning system in your Ford Mustang started blowing warm air year-round?  Air conditioning system repairs can get to be very expensive but before running to your mechanic there are some steps that you can take that could save you some money.

First, look around under the hood of your Ford Mustang for the air conditioning systems decal.  Here, you will get the basic information that you need to service your AC system including the type of refrigerant used in your Mustang.  Older models will use R-12 whereas newer Mustangs use an eco-friendlier R-134a type refrigerant and while you can retrofit an older vehicle to accept the newer Freon, it is important never to mix the two as it can ruin the system.

The most common culprit in a warm-blowing air conditioning system is a refrigerant leak so once you know what type of Freon your Mustang takes; you can head to the store and purchase a kit to recharge the system yourself.  Before doing so, it is wise to visually inspect the air conditioning system starting with the silver tubing running from the firewall to the compressor located atop the engine and the components located in front of the car, near the radiator.  If you have a massive Freon leak, such as a cracked line or a major leak at one of the system components, you may be able to notice it with the naked eye but in most cases, the leak is small and hard to see.

If you find no signs of a leak, your best bet is to recharge the refrigerant.  Once you do, if everything else is in proper working order your Mustang's air conditioning should go back to blowing nice cold air.  If it is cold at first but fades over time, you know that you have a small leak somewhere.  Most parts stores and auto supermarkets now sell air conditioning system sealant that is introduced to the system in the same manner as the refrigerant and I have firsthand experience with this product and it worked very well - allowing the car in question to continue blowing cold air for several years after being added.  This system sealant helps to soften the rubber gaskets and O-rings throughout the system that can often be the source of the Freon leak and this is a cost-effective way to try to fix your Mustang's air conditioning yourself.

If recharging the system seemingly has no effect or the air only blows cold for a very short time after recharging the system and adding the sealant the odds are good that you have a more serious issue in the system.  The act of physically replacing one of the major components like the condenser, compressor or evaporator might seem simple enough but per Federal law, a special evacuation system is required to remove all residual refrigerants in the system and getting caught fixing the system without the proper tools can result in a stiff fine.  The machinery required to properly evacuate the AC system is very expensive and this is why many shops do not offer air conditioning repair so your best bet in getting a reliable job done on your Ford Mustang's air conditioning system is to find an air conditioning repair specialist in your area and make the call.  Remember, not only is it illegal to simply release the refrigerants into the atmosphere, but in the proper conditions a release of Freon can be very deadly - suffocating anyone around if released in a confined area.

A visual inspection may not reveal much but adding an air conditioning system sealant and using a refrigerant recharging kit may save you hundreds and keep your Mustang's air conditioning blowing cold for years to come.
