When it’s hot outside the last thing you want is for your car’s air conditioner to stop working. Unfortunately this is a common problem. Luckily it’s usually easy to fix.
The first thing you need to do is figure out where the leak is coming from. The most common place for leaks is the O-ring. This is a small rubber ring that seals the connection between the compressor and the evaporator. If this O-ring is damaged it will allow refrigerant to leak out.
To check the O-ring disconnect the negative battery terminal. Then remove the bolts that hold the compressor in place. Once the compressor is removed you should be able to see the O-ring. If it’s damaged replace it with a new one.
If the O-ring isn’t the problem the next most likely cause of a leak is the evaporator. To check the evaporator remove the bolts that hold it in place. Then take a look at the seals. If they’re damaged you’ll need to replace the evaporator.
If you can’t find the source of the leak the next step is to evacuate the system. This means removing all the refrigerant from the system so you can start with a fresh charge.
To evacuate the system start by disconnecting the negative battery terminal. Then remove the bolts that hold the compressor in place. Once the compressor is removed you should be able to access the refrigerant lines.
Use a refrigerant recovery machine to remove all the refrigerant from the system. Once all the refrigerant has been removed disconnect the hoses from the evaporator and compressor.
The last step is to recharge the system with new refrigerant. Follow the instructions that come with the recharge kit to recharge the system.
If your car’s air conditioner is leaking don’t wait to fix it. A leak can quickly lead to an empty system which means you’ll be stuck in the heat. Follow the steps above to find and fix the leak then recharge the system with new refrigerant.
