How To Add Refrigerant With Gauges (DIY A/C Recharge)

- In this video, I'm adding R134a refrigerant to my 2015 Chevrolet Silverado. I know this truck has a small leak, so I'm adding refrigerant until I can fix the leak. I'm just trying to make it through the summer. The gauges I'm using are harborfreight. You can get a similar set (and probably better set) from my Amazon Affiliate link here-
A/C Gauges

Since 2018, all cans sold in the U.S are required to have a self sealing valve, the old ones were open once pierced like you said. The two different cans require two different can taps or an adaptor.
Good to know, thanks
I'm sure you did this off camera, but be sure and let folks know to purge that low pressure hose as well. It is a great idea to purge all hoses before the addition of refrigerant so that no air in your system.
Yes, absolutely, good catch.
The way you are telling it means that there is no need for a vacuum pump.. Because I have put r134a gas in the car without a vacuum pump but cold air does not come out??.
If you're "topping off" the system, then there is no need to pull a vacuum, so there is no need for a pump. You pull a vacuum when the system is empty (like after replacing a compressor) to remove any moisture from the system. I will also have a video coming soon of this process.
But if my gas escapes through a hole, shouldn't a vacuum pump always be used?
@gb7705 Ultimately yes when you replace the part that is leaking, but if the system is holding pressure (which you would need to check with gauges) you don't need to pull a vacuum to top it off. The pressurized system, in theory, should keep out the moisture. If your system will not hold pressure (like overnight), then it will not hold a vacuum either, so you will need to find the leak and fix it. Otherwise, you're wasting your money on freon. If your system has the pressure, it's supposed to and is still not blowing cold, then you have a problem other than freon.
@@chrisryansworkshop7519 When I took it to the mechanic, he gassed it without any problem with his vacuum device,,, I don't understand why when I only gas r134a, the mammometer shows 50psi and the car still doesn't cool. This means that the compressor is very good.. I just can't find a way to fill the car with r134a gas myself without going to the mechanic

Low side need to be from 30-40 max...do not add over that...hi side from 150-170-200 max
