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 incorrect with the refrigerant system, however one of the crucial widespread is a refrigerant leak. Should you suspect that your refrigerant system is leaking, you will must recharge it.
Earlier than you begin, you will want to assemble a couple of provides. You may want a refrigerant recharge package, which you could find at most auto components shops. You may additionally want a set of wrenches and a screwdriver. After 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 positioned underneath the hood of your automotive. It is normally on the passenger aspect of the engine. As soon as you’ve got positioned the refrigerant system, you will must determine the low-pressure aspect. The low-pressure aspect is normally the smaller of the 2 strains on the refrigerant system. It’ll even have a blue or inexperienced cap on it.
Connecting the Recharge Equipment
As soon as you’ve got recognized the low-pressure aspect, you’ll be able to 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’ll be able to open the valve on the refrigerant recharge package. This may enable the refrigerant to start out flowing into the system.
Because the refrigerant flows into the system, you will want to observe the strain gauge on the recharge package. The strain gauge will let you know how a lot refrigerant is within the system. You may need to add refrigerant till the strain gauge reaches the specified stage. As soon as the strain gauge reaches the specified stage, you’ll be able to shut the valve on the recharge package.
As soon as you’ve got closed the valve on the recharge package, you’ll be able to disconnect the hose from the low-pressure aspect. You’ll be able to then substitute the cap on the low-pressure aspect. As soon as you’ve got changed the cap, you can begin your automotive and activate the air conditioner.
