If you're using the auto parts store version of this kit, you'll simply inject a small can of UV dye into the air conditioning system through the same charging port you use to add freon. If the air conditioning system is still operational there should be sufficient pressure in the circuit (at least 3,5 bar), to carry out an effective leak test. Then use the vaccum to pull your freon in as much as possible. To begin testing a component, a nitrogen tank or on-site nitrogen generator will be connected to the component. Our certified mobile mechanics make house calls in over 2,000 U.S. cities. A warm liquid line from the condenser to the evaporator (before the expansion valve or fixed orifice tube). ALWAYS wear appropriate protective clothing, including gloves made of fluoroelastomer (leather or fabric gloves are not suitable when servicing any part of a refrigerant system). Testing 1) If the air conditioning system is still operational, recover the refrigerant. FREE Shipping by Amazon. Automotive A/C Nitrogen Leak Detector Kit Easily pre-check systems for leaks due to loose mechanical connections, hose leaks, evaporators and condensers without using refrigerant and venting into the atmosphere. Step 1: Park your vehicle on a level surface. Voltage is not sent to the clutch when the air conditioning is turned on due to an open circuit in the electrical circuit. google_ad_client="pub-3815356937174265"; Insert an accurate thermometer into the lower fins of the condenser. You need to determine if there is refrigerant in the system. In pressure-testing, you use a moisture-free inert gas to pressurize the A/C system.

nitrogen testing car ac system

I got my old stock AC working and switched to 134 about 4-5 years ago on my SC by pressurizing the system with air and then spraying everything with soapy water (I simply dump about an ounce of dish soap in a spray bottle filled wih water) to find the leak (AC line by the jack port was damaged by the PO and was the source of the leak). When adding refrigerant to the system you want to take it slow as you do not know how much it actually needs. A simple but effective initial test is to check the temperature of the refrigerant system components and lines by touching them while the system is operating.
