can you charge the AC in an international just like you would any other car?

2019 chart

 

Is that with the fan on or off?
21st century or 20th century?
Cars or semis?

I'll let you in on a little secret.

Today's regulations don't use charts that are outdated.

And if you follow today's regulations. You won't be anywhere near what that chart says.

 

@ 95*
My 17 chev kicks fan on at 350. Shuts fan off at 250. Low pressure stays at 30

My sons 16 mazda. Runs with fan. 275 and 30.

Both cars serviced in accordance with today's regulations. Both cars serviced with the proper technique also.

Checking it at idle isn't the proper technique. Cars spend 95% of their time driving.

 

Those charts are current, and pressures accurate. 35-50 on the low side. Is perfect. As far as quantities are concerned. It’s listed on every vehicle, by weight. I’m not licensed, but have gotten most info from books, and my brother in law, and a friend of mine. Both Commercial Licensed. Including, Ammonia. They’ve given Me enough info, on any hvac. I even did central air myself. Nowhere near knowing everything, always something new to learn with hvac. lol If I Were licensed hvac, I doubt I’d Own a Trucking Co. I’d own an Hvac co.

 

Here's my car. It don't match the chart

 

I get your point, on pressures. I was amazed at all the different high pressure switches available on Vehicles. I have a catalog for part #s and such. Freightliner alone has a bunch of different hp switches, open/ close pressures with big variables. I, honestly wondered about that. Seems they’d all have same limits. Always something to learn on hvac. Endless.

 

Well , I hope you got that problem fixed!!! Lol, I’m only joking!!!!
Looks like it did match the chart, each individual readings within the limits. Not each side match perfectly, all fluctuating. But with in limits.So many variables, I always put the exact amount, posted on firewall. And go from there. Two things I learned the hard way recently, is don’t over fill in liquid ( can upside down) it really will split a compressor wide open. Lol. I did that last summer, thinking it was low, but had a bad HP sensor. And Too much oil, causes compressor to run hot. Never would have thunk it. And I used the green dye, made finding a pin hole in condensor this year a Breeze. No ultra violet light needed. Bright green clear as day. Thnks. Always looking for more info.Just when I think I’ve figured it all out.......

 

so it at idle

 

At the beginning of video if it's there. I tell my son to rev the motor.

2000 rpm on cars.

2 things. You get a more accurate reading since motor spends most of it's time running down the road. And with the fan on. You're simulating actual driving conditions. Motor going down the road with air flowing through the condenser.

Compressor will charge much faster.
I never go above 250 - 275 on cars. With fan running. 140 on semis.

Earlier cars run the fan like my boys 16 mazda.
My 17 cruze and buddies 15 Toyota pickup use the high pressure awitch.

My w900 runs at 140 with the fan on.

Ideal low is 30 to 35.

If I were to use the chart. I'd be wasting everyone's time. Everyone would be blowing warm.

When I started 30 years ago. When 12 was the thing. I used a thermometer for the vent temp. Pressure always came out the same for coldest point.

Hard to do with 134 because it takes longer then 12 to cool down.

I've also had a couple of classes.

I don't use cans. I have 30 lb cylinders. Need a license to buy over 2 lbs. Yet you guys can buy all the cans you want.

 

i tknew this would get technical haha
