New A6 compressor/new POA valve ?

aquartlow on Tue June 04, 2013 8:15 AM User is offline

Year: 1979
Make: Ford
Model: Ranchero
Engine Size: 460
Refrigerant Type: R12
Ambient Temp: 90'
Country of Origin: United States

Looking to replace my leaking A6 compressor(front seal), with either an S6 or Pro6ten aftermarket direct replacement. When I replace the compressor should I also change my POA/STV for the new cycling style of POA. My system has(had) R12 and worked great until the front seal let go. I received great information and guidance when I was getting this A/C system assembled/running last year, just want to know your opinions on the A6 replacement compressors( which has the least known problems, I realize I asked a preference last year but didn't know if any recent problems have arisen with the use of either of the newer compressors) and if my POA/STV needs changing. I will be recharging the system with R12. Thank you in advance. Todd

Why not just replace the front seal?

-------------------------
The number one A/C diagnostic tool there is- is to know how much refrigerant is in the system- this can only be done by recovering and weighing the refrigerant!!
Just a thought.... 65% of A/C failures in my 3200 car diagnostic database (GM vehicles) are due to loss of refrigerant due to a leak......

Do not convert to a cycling system unless your POA valve is faulty and you can't find a replacement. A properly working POA system is much better than those conversions. Only the people selling them call it an "update".

Thank you for your reply GM Tech.
Too many seal leakage problems for me to risk losing more R12. When I completely went through this system last year, I previously purchased a remanned A6, thoroughly cleaned the system, tested the POA/STV, replaced the condenser, expansion valve and the drier, vacuumed my system down, added the proper oil and amount, charged it and the reman didn't last 2 weeks before the seal gave up. I love the cooling ability/capacity of the A6, just not the all too common front seal problems. I'll have too much time, labor and R12 involved to roll the dice on another A6. Todd

Thank you for the information mk378, much appreciated. I received info last year while redoing this system that the A6's clutch wasn't meant for a cycling type of POA, wasn't sure about the new A6 placement and it's clutch. My POA valve works/worked as it should(as per POA valve checking instructions). I hope redoing this A/C system isn't a yearly occurance. Do you have an opinion on which aftermarket A6 compressor to choose? Todd
