E150 OK?

OHfordMan on Tue July 28, 2009 11:43 PM User is offline

Year: 1999
Make: Ford
Model: E150
Engine Size: 5.4
Refrigerant Type: 134A
Ambient Temp: 80
Pressure Low: 45
Pressure High: 200
Country of Origin: United States

My E150 Conversion van with Pro Air rear air doesn't seem cold enough. Vent temperature was 50-52 degrees F today but I think it should be colder. What is a normal vent temperature and corrective actions if required. Note the fan clutch on this van was replaced a few years ago so I would think it is OK.
Thanks in advance
OH Ford Man

Low side seems a little high. I would try spraying some water over the condenser while at 1500rpm and see what it drops to.

Thank you for your reply. Tried the water and got the following results: At idle with water low 38, high 125, vent temp 45 F; at 1500 rpm 32 low, 170-175 hihg, vent temp 40 F. One other thing to consider - I added refrigerant assuming it was low which may not have been the case. Could this have too much? I don't recall added any in past for this 10 year old van. - OHfordMan

If you know the refrigerant capacity for that van, it might pay to recover and recharge to factory specs, it is more than possible you lost some during ten years.. If the "misting" of water on the condenser dropped the high side like a stone, you have an airflow problem and a new clutch fan may be needed. Spraying water on the condenser means to mist it, not soak it... Hope this helps..
