meaniless without knowing ambient temp.160/35
160/35
When the system is running the pressures are always changing, if inside a shop what is the room temp? The discharge side will be constantly building as the suction side drops. The suction side low pressure valve cuts out at approx 26lbs, then the system will attempt to *stabilize*, the low side rises, the switch will close at approx 42lbs. and the cycle begins again. So what are both gauges reading thru-out a cycle?
Ford uses a *clutch time* on, *clutch time* off, *clutch cycle rate* per minute to determine system performance.
The static pressure when the system is not in use should be approx 100lbs. The system should hold 30 oz.
The gauges didn't really move much they stayed pretty much 160/35. approx ambient temp was 70F
The sticker on the rad support said 1 lb 14 ounces so that is the charge it has.
When it is working the air is a solid 40F so it works well when the compressor is on1 lb/14oz is 30 oz.
160/35,
that doesn't seem quite right, at 70F there should be a continued cycling, you'll see that on the gauges moving up & down constantly, if the suction side is holding at 35psi the low pressure switch will not open & the system will not cycle as it should do, possible sign that the system is not building discharge side pressure because of possible low refrigerant or the orifice tube is not creating a restriction or the compressor is struggling.
At suction side 26lbs. when the low pressure switch opens the discharge side should be over 200lbs.
When it is working the air is a solid 40F so it works well when the compressor is on
