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 fallacious with the refrigerant system, however one of the crucial widespread is a refrigerant leak. When you suspect that your refrigerant system is leaking, you may must recharge it.
Earlier than you begin, you may want to assemble a couple of provides. You will want a refrigerant recharge package, which you could find at most auto components shops. You will 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 situated below the hood of your automotive. It is normally on the passenger facet of the engine. As soon as you have situated the refrigerant system, you may must establish the low-pressure facet. The low-pressure facet 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 Package
As soon as you have recognized the low-pressure facet, you may join the refrigerant recharge package. To do that, merely screw the hose from the recharge package onto the low-pressure facet. As soon as the hose is linked, you may open the valve on the refrigerant recharge package. This may permit the refrigerant to begin flowing into the system.
Because the refrigerant flows into the system, you may want to observe the stress gauge on the recharge package. The stress gauge will inform you how a lot refrigerant is within the system. You will need to add refrigerant till the stress gauge reaches the specified stage. As soon as the stress gauge reaches the specified stage, you may shut the valve on the recharge package.
As soon as you have closed the valve on the recharge package, you may disconnect the hose from the low-pressure facet. You possibly can then substitute the cap on the low-pressure facet. As soon as you have changed the cap, you can begin your automotive and activate the air conditioner. It’s best to now have chilly air blowing out of your vents.
Checking Refrigerant Ranges
Checking refrigerant ranges is a vital step in recharging the AC system in your 2013 GMC Terrain. To test the refrigerant ranges, comply with these steps:
