My information shows it to be, an evaporator mounted OT. Check the liquid line outlet on the evaporator.

I do not believe this compressor has a relief valve on it. But might double check the back of the compressor. Question I have, is compressor is leaking refrigerant badly when operating. Is someone just adding more and more refrigerant? What are the pressures? Are the electric fans coming on correctl...

Each compressor has its own resistance. An A6 will take a lot more torque to turn compared to a Scroll compressor. Most compressors can be turned by hard with reasonable resistance.

Be interesting to know what refrigerant you are using.

Add 80% to the compressor via the suction port. 20% to the accumulator.

Hard to beat you listed pressures. IS the capillary tube on the exp valve attached to the suction line and wrapped with moisture resistant tape? The system is using the 99' Mercury OT, the TXV was removed as the plumbing was deemed too difficult at the time of installation... Personally, i would ch...

Thanks Tim, Not what I wanted to hear, but better than building an ineffective system. The link you provided is good; lots of evaporators to choose from, but unfortunately no measurements. Do you know of an evaporator that is approx 9" x 5"? Thanks again, Paul I can check with a coil comp...

Hi, I am building a custom AC and I have been trying to find a small evaporator 9" wide by 5" high. the only evaporator I can find is from a Freightliner http://www.ebay.com/itm/New-Heater-Evaporator-coil-Fits-Freightliner-with-OEM-N83-315910-/291646128186?hash=item43e776c03a:g:4eUAAOSwNy...

Not that I'm aware of. If you get a better image of the connection. I believe that primary valve is replaceable.
