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 probably the most 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 assemble just a few provides. You will want a refrigerant recharge equipment, which yow will discover at most auto components shops. You will additionally want a set of wrenches and a screwdriver. After you have 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 facet of the engine. As soon as you’ve got situated the refrigerant system, you will must determine the low-pressure facet. The low-pressure facet is often the smaller of the 2 traces on the refrigerant system. It’ll even have a blue or inexperienced cap on it.
Connecting the Recharge Package
As soon as you’ve got recognized the low-pressure facet, you’ll be able to join the refrigerant recharge equipment. To do that, merely screw the hose from the recharge equipment onto the low-pressure facet. As soon as the hose is linked, you’ll be able to open the valve on the refrigerant recharge equipment. This may permit the refrigerant to begin flowing into the system.
Because the refrigerant flows into the system, you will want to observe the strain gauge on the recharge equipment. The strain gauge will let you know how a lot refrigerant is within the system. You will 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 equipment.
As soon as you’ve got closed the valve on the recharge equipment, you’ll be able to disconnect the hose from the low-pressure facet. You’ll be able to then substitute the cap on the low-pressure facet. As soon as you’ve got changed the cap, you can begin your automotive and activate the air conditioner.
