Engine Size: 3.0
Refrigerant Type: R-134
Ambient Temp: 90
Pressure Low: 60
Pressure High: 225
Country of Origin: United States
I have 225 on the high side and 60 on the low side. Inside the car it reads 70 degrees. Is it possible that the expansion valve is wide open and its not atomzing the refrigerant thus not restricting flow from high to low creating more pressure on the low side? Or is it possible that the system was overcharged trying to increase high side pressure?
Although it has never happened to me, I wonder if the expansion valve is open and letting pass the refrigerant thus creating a higher reading on the low side with 225 on the high side(which at that pressure should cool) but if it's not atomizing then it wouldnt cool..
Any help would be greatly appreciated.
I would suggest a subscription to Mitchell. There is a sequence of test that can be preformed to help with these types of issues. Will all the different senors on these system it almost a must. Exp being bad. Always a possibility but I doubt it in this case.
