It depends on the outside temperature but the average low side pressure should be around 35 to 40 psi and the high side should be no higher than 250 psi..........
depemds on the car as how much freon it will hold. some cars have a tag saying how much freon the car is filled with. Too much freon is just as bad as not enough freon.
1.88 pounds of 134
Yes. there is a low and high pressure cutoff switch for the newer cars 1995+
A leak, either the pressure line or somewhere in the compressor.
I have a 1999 chevy lumina 3.1 engine and i need to know how much freon to put in.I just bought a pressure gauge and i don't know how much freon to put in. Thank you! Michael Hendrix
take it to someone that can reclaim it
Never add freon to your own car. This is very dangerous and can kill you. A/C systems are very high pressure and If you buy a freon kit to add freon to your car. It will be propane which is highly flammable. Take it to a dealer to get it done. Also if you ever add it and it is leaking out then it can explode if it gets near a spark.
yes, it will blow out your seals. causeing all the freon you just put in to leak out. yes
To add refrigerant to a Hyundai Sonata first find the inlet for the low pressure charging port. Be sure the vehicle takes 134a refrigerant and use the can of freon to appropriately add the proper pressure to the car. Overfilling the freon into the vehicle well lead to cooling issues.
By buying an AC charge hose and a can or 2 of R134a freon (depending on how much your car needs) Attach hose to the low pressure side & charge system. Do not overcharge, or you may destroy the AC system.
The truck doesn't have a freon pressure gauge. That is a tool that the repairman/mechanic has.The truck doesn't have a freon pressure gauge. That is a tool that the repairman/mechanic has.
Freon may need to be added when the ac is not blowing cold enough. A Freon gauge can tell you for sure if the pressure is low.
