Accessing the Refrigerant System
The refrigerant system is what makes your air conditioner chilly. If it isn’t working correctly, you are not going to have any cool air blowing out of your vents. There are some things that may go unsuitable with the refrigerant system, however one of the frequent is a refrigerant leak. For those who suspect that your refrigerant system is leaking, you will must recharge it.
Earlier than you begin, you will want to collect a number of provides. You will want a refrigerant recharge package, which you will discover at most auto elements shops. You will additionally want a set of wrenches and a screwdriver. Upon getting your provides, you can begin the method of recharging your refrigerant system.
Step one is to find the refrigerant system. The refrigerant system is situated beneath the hood of your automotive. It is often on the passenger aspect of the engine. As soon as you have situated the refrigerant system, you will must establish the low-pressure aspect. The low-pressure aspect is often the smaller of the 2 traces on the refrigerant system. It’s going to even have a blue or inexperienced cap on it.
Connecting the Recharge Equipment
As soon as you have recognized the low-pressure aspect, you possibly can join the refrigerant recharge package. To do that, merely screw the hose from the recharge package onto the low-pressure aspect. As soon as the hose is linked, you possibly can open the valve on the refrigerant recharge package. This can permit the refrigerant to begin flowing into the system.
Because the refrigerant flows into the system, you will want to watch the stress gauge on the recharge package. The stress gauge will inform you how a lot refrigerant is within the system. You will wish to add refrigerant till the stress gauge reaches the specified stage. As soon as the stress gauge reaches the specified stage, you possibly can shut the valve on the recharge package.
