AC Recharge Basics
“R-22 should NOT be used in a R-134a system. It may damage the compressor. R-22 is a high pressure refrigerant; R-134a is a low pressure refrigerant.”
“You don’t need to run the system to find out if it is full or not… With a cold engine, attach a gauge and check the pressure… The pressure should be a few pounds higher than the ambient temperature.”
Is this a safe pressure for the AC?
AC Recharge Basics: Ok so this is what i did. I drained as much of the r2 out as possible, went to walmart and got a can of ez chill 18oz with oil and sealers. Now i notice the only way it will cycle on is if i jumper the low pressure switch.
And then the coolant gets in there and it stays on when i replace the switch, otherwise if i don’t jump it no matter how much coolant goes in there it goes on and off on and off. It was like 61 degrees f. And i added the whole can witch was about 25 psi. And the temperature chart said for 65 to put 25-35 in so after putting the whole can in, the compressor was staying on and cold air starting blowing.
Now when i hit the gas with the pressure gauge still hooked up the pressure actually goes up and shuts of the compressor. Now when i was adding the r22 yesterday when i hit the throttle the pressure lowered. What do you guys think i am a little short on coolant? 25 Is the lowest range in the full section its 25-35 when its filled. I haven’t took it for a ride yet to see if the compressor stays on while driving.
I think it’s because i had about 45 psi.
I put 18 oz can in there do you guys think i will need more or what? In the manual it says the system holds 1.65 Pounds witch if i am correct is 26.4 Oz and the can says it contains 15 oz r134a, 3 oz system safe leak sealer,lubricant, ac performance booster and ac system cleaner. What would cause the pressure to go up when i hit the gas(not floor it) all i did was tap the throttle under the hood and it shuts of the compressor? And then when it returns to idle it comes back on and stays on blowing cold air. And yesterday when i had the r22 it ran perfect no shut offs or pressure builds. So i think i will put it to about 35 psi and then see what happens. But lemme no if u guys no anything thanks
