#How to use ac recharge kit how to
While these steps explain how to recharge the car AC after compressor replacement, you need to be sure you are comfortable doing it. Look at a compressor issue that maybe occurred when you replaced it. If the compressor is not engaging, do not add more refrigerant. If you put in too much, you are going to need a mechanic to fix it as you can not let out the refrigerant into the air since this is illegal. Make sure the dispenser is connected properly as well. If it does not work, check the needle on the gauge because it takes a lot of time for the refrigerant to rise in pressure. Now your car’s air conditioning should be nice and cold. When you are done, leave the extra refrigerant in the can, attached to the dispenser. Keep the dispenser on the fill port while emptying the can unless you are completely done. Take the can off the dispenser and put a new one on. If the can empties before you are done filling, turn the empty can upside down, pull the trigger for at least 30 seconds, then let the trigger go.

Do a final pressure check and put the cover back on the fill port. Stop filling when you get to the right pressure range. If it is still low, add more refrigerant. Only do this measurement when the compressor is going. Wait 30 seconds for the pressure to equalize. Pull the trigger for five to 10 seconds while you slowly tip and shake the can. If it is below the minimum pressure, start filling the system. Some gauges show a “V” that is adjustable and shows a good pressure range. It tells you the minimum and maximum pressure that is ok for the outdoor temperature. Know the right pressure to fill to using the table that comes with your dispenser. Keep the trigger squeezed to make sure the AC refrigerant is constant as it will keep outside air and moisture out of the system. Make sure the connector is on properly and seated on the port. Let go of the outer sleeve of the connector and then the connector, too. Put the connector tight on the fill port. Lift the sleeve while squeezing the trigger. Squeeze the trigger for at least two seconds so you can get rid of any air in the hose. Take the outer sleeve of the connector and lift it. The dispenser should be connected at the end of the hose. Once these steps are done, move into this next section fairly quickly so make sure you read through them first so you know what to do. While the engine runs and the AC is on max, do the entire filling regimen. If the compressor still does not go, you may need a mechanic. If it is not, you need to put in half of a can of R-1234a as outlined in the next steps. If it is then the compressor is doing what it’s supposed to. Make sure the middle of the pulley is turning. 
Find the pulley that is on the compressor.These are small hoses and they will be hot. Do not touch the high-pressure side hoses. It is often a section of metal pipes with the hose coming from either end. It is usually on the left side of the engine bay and has a small plastic lid with an L on it. Trace the hose that goes from the low side fill port to the compressor.Put the fan onto the highest it will go.
