The vehicle is a 1997 FZJ80. The AC system performance is poor. I have tested the system with gagues and everything is within sped. Does anyone have data from an infrared thermometer? I woulld be interested in 8 readings:
The expanson valve in - 150 degrees F
The expansion valve out - 129 degrees F(on my home system this is approxamate the outlet air temp - I do not understand this reading )
The compressor in (low) ~140 degrees F
The compressor out (high) 215 degrees F
The condensor in 215 degrees F
The condensor out 150 degrees F (this appears to be way too high - I will test water on the condensor to see if that helps lower the system temp) (the performance at idle is way poorer than at 35 MPH)
The ambiant temperature at the time of the reading - 100
The air out temperature at the vents. - 70
I am trying to diagnose either fluid contamination, a bad expansion valve, or ???
The air outlet drop at 100 ambiant is 30 degrees.
It appears as though the whole system is running hot. I will try insulating the return path into the compressor. That is routed past the exhaust, I suspect it is heating the entire system.
Thank you in advance. Dan
