A vacuum pump must be attached to both the low and high air conditioning system sides for at least 5 to 45 minutes. Park your car in a well-ventilated area and open the hood. Step 2: Charge the low side valve. This is caused by the absorption and steady release of the refrigerant chemical in the compressor oil. You need to press the plunger valve to release the refrigerant. Most of the pumps that Harbor Freight carries are two-stage units. Running the friction for a few minutes will bring the pressure on the high and low sides close to equilibrium. To fix it, push down the knob and snap the hose on the service port and let go. Then, to drain liquid from the AC system, open the blue liquid valve on the manifold gauges. When you sit in your car hoping to get a cool breeze of air from the AC, and it doesnt work, how do you feel? If the water condenser on the ac system condenses, the ac might freeze. Hook up your vacuum pump to the low pressure side of the AC system. In many cases, the performance efficiency of your AC system is affected by the difference in refrigerant levels. After pulling a vacuum you should shut the valves and turn off the vacuum pump. As soon as you introduce the refrigerant in the air conditioning, switching off the compressor would help. Depress the access valves on the AC system by installing access valves on the high and low sides of the compressor. Sometimes the AC system can be found to be beyond repair and will need replacing entirely. If there are leaks in the system, the refrigerant gas contaminates the environment and causes the air to become stale. changle oil, filters and inspect safety systems in your car Looked under my car, the middle under carriage was gone lspencer_1975 in San Leandro, CA on February 17, 2015 The standardly equipped Touareg V6 . Also, make sure youre using the correct type/brand of Freon for your car as indicated in the owners manual, or ask the auto parts store clerk what would work best for your car if not sure. Adjust the pressure to 14 psi on the low side valve, run the friction for a few minutes to bring both the high and low sides to a more balanced equilibrium. , one should know that it is possible but would not be that efficient. The evaporator absorbs heat from the air to evaporate the refrigerant and cool the incoming air. Evacuation Procedure 1. 4. How much vacuum should an AC system hold? Depending on the type of AC system you are working on, you may need to make some adjustments in the given process. After installation of the replacement kit, the pressure gauge would show the state of charge on the low-pressure side of the system. Thats because when the air conditioning system is continuously exposed to the atmosphere, air, humidity, and moisture might get accumulated in the system and affect its performance. Put the caps and the hood back on. and seems to have a lot left when I shake it. Attach the pump hose to the low-pressure port of the refrigerant gauge. This is enough time period to get rid of moisture and dust inside the AC system. Hold down the access valve on the high side of the system while bringing the pressure down as far as it can go on the low side.
