How To Refill Ac Refrigerant In A Car(in empty system)

[plips]

If it was empty the compressor should not have kicked on at all, how did you pump in the freon? Need to recharge my '16 Tahoe without paying $200 when I have 2 cans, wouldn't you have to jump the low pressure switch to force the compressor to run? Thanks

I had done this today. But my question is I screwed the freon can I had an issue in some way it was able to go on to the gauge but it was like someone crooked is there any way that that can be cross-threaded the gauge that I use

WRONG! You need to start the engine, so the liquid does not damage the compressor when filling. Thats the reason you START car and FILL SLOWLY.

Where did you get the kit and how much, thanks.

Hello,

I have a question.

I just tried to fix my airco in my Kia Picanto 2012 with one of those simple kits with a can of refrigerant, and a hose with a gauge. (mine did not come with a temperature setting). My airco had just gradually become less cold over the years and now it had completely stopped working.

I was hoping for a quick fix for now, but it didn't work out so far.


When I connected the kit with the gauge to the low pressure side, it showed no pressure at all. Then I filled it untill it showed 60 PSI, with the engine and airco on. (was aiming for 50 but gone a bit too far).

After that I drove around the block and when I drove away, cold air was coming out of the vents, and I thought it was a succes! but.. this only lasted for a very short time, a minute or so. (that doesn't sound too good, right)

So now the airco still doesn't get cold.

Now, when I check the pressure on the low pressure side, the gauge shows 60 PSI, engine and airco on, or off, there is no difference. Also, the pipes don't feel cold at all.

Since it is also showing 60 PSI with the airco and engine off, I'm thinking... maybe there is still not enough pressure, because with the airco off, the pressure should rise far into the red zone... (like 100 PSI) if i'm right?

Do you think it's worth it to try and get another can of refrigerant, to build up the pressure and see if the airco will actually activate?

(I can't seem to spot any compressor pulley turning on and off when I turn on and off the airco, everything seems to be turning always, even with the AC button off. But the fan on the front of the car does turn on and off with the AC button.)

(one more thing. I was too quick to do it, and kind of forgot about the temperature thing. I think it was about 68 degrees fahrenheit here when I filled it.... So according to the temperature/PSI charts, according to that I should have filled it to about max 35 PSI... and I filled it to 60 PSI.... So Im kind of worried that I have destroyed my AC system. But, since it's also showing 60 PSI with the engine and airco off... I doubt this, and start thinking the pressure is actually too low?

I hoping you could shed some light on this!

You didn’t vacuum the system out good luck on the long run
