- When to use the aircontopup.com Leak Sealer Kit system
When automotive air conditioning systems are low on gas the air they blow out will not be as cold as when the system is fully charged. If the system is totally out of gas it will cease to blow out any cold air at all. Using the aircontopup.com Leak Sealer Kit you can seal your own system and prepare the system to have freezing cold air again. The special sealer will seal small holes in plastic and rubber ‘O’ rings by swelling them slightly. This particular kit is designed for use when you are certain that your system is totally out of gas and you are trying to repair any leaks. You will usually find that an empty system will obviously have no pressure in it and so will not be able to start the air con compressor. Most air con compressors are pressure fed and so will not function with no pressure.
- How to tell if the compressor is running
It is very important to be able to tell if the compressor is working, if it is working then you are most probably not empty on gas.
There are 2 easy ways to identify if the compressor is functioning :
Firstly when you switch the air conditioning on you should hear a small click and the engine should increase its’ rev speed. This click is the compressor coming on. If you hear this then it is working fine.
Secondly if you are able to identify the compressor in the engine compartment then you will see it spinning when the air conditioning is switched on and then stopping when it is turned off.
- Adding STOP LEAK
You must connect the hose to the low pressure charging port of the vehicle. There are 2 ports on a vehicle the high and low, the gauge will only connect onto the low port so no mistake can be made.
With the hose separated from the car, wind the tap of the hose completely to the up position. Carefully screw the can of STOP LEAK on to the tap end of the hose making sure it is not cross threaded. Screw it on tightly and then back half a turn. Connect up the hose to the low side port connecter of the car (Hold back the plastic ring, push the connector on to the port and release the ring, you should here a click as the connection is made)
Ideally the outside temperature should be above 15C/58F, turn the engine on and set the air con in the car to its’ coldest setting and use the recirculation option if applicable and leave all vents open with the fan on full.
Once connected to the car with the can attached to the hose turn the tap into the fully down position, this will both pierce the can and close the valve stopping any leakage. Invert the can then unscrew the tap slowly to empty the contents of the can into the A/C system.
Once the contents of the can are empty screw the tap back down to close off the can.
Turn the engine off then disconnect the hose from the vehicle and then unscrew the can very slowly from the hose pointing it away from you as the last of the gas may still have to escape.
- Has it worked ?
Now that you have added the leak sealer you need to know if you have been successful. Just wait an hour and then come back to the car and check if the compressor is now functioning (as you did before). If the system has held pressure and the compressor comes in as it should then you have repaired the system. You can now go ahead and use our AIRCONTOPUP KIT and add the gas to make the air con ice cold.
If the compressor is still not working then the leak is more likely to be in a metal part of the system and you will need to go to a specialist repair shop armed with the knowledge that it is major leak.
