Ocassional lurker on this forum, first post.
Planning overhaul/upgrade to stock A/C on 1987 Porsche 911 to survive hot humid Atlanta Summers.
I'm still waffling on staying with R-12 or switching to 134a and would be interested to hear the experts opinions here. My proposed 4 condenser system was "engineered" to run 134a .....but how much better would my system perform if I stay with R-12?
Project details (parts on order):
1. Complete barrier hose set
2. Duel Kuehl "Griffiths" rear fender condensers with fans
3. OEM tube & fin Rear deck condenser replaced w/new last summer w/ 3 puller cooling fans added
4. New Kuehl dryer (just not sold on the ProCooler)
5. New serpentine evaporator
6. New serpentine front condenser
7. Reman Nippondenso 10P15C Compressor
8. Flush rear deck condenser only - all other system components will be new
Planning on doing the install myself and having the local Porsche dealer do the evac and recharge (great tech who specializes in older air cooled cars - he suggests staying with R-12 due to the small size of the 911 evaporator).
Conversion to 134a requires the installation of a hi/low cutoff switch (got one comming with my new parts). Do I add the switch if I stay with R-12?
You do not need the high pressure cut out switch if staying with R12.
Some (many) people feel the same way with R134 because I rarely ever see them on most conversions.
A cut out switch is not needed for R12. But it sure is nice to have one if you want a chance of saving a compressor if the system decides it wants to have a leak. R12 is widely available and since these vehicles have poor air flow. I personally would stay R12.
Can I flush the rear deck lid condenser without removing it from the car? Was thinking about doing so using a pressurized garden sprayer to run some mineral spirits through it then blow it out with pressurized air.
When flushing the goal is to remove debris, oil along with all of your flushing agent. Component being mounted or not is not an issue. Just remember if you leave flushing agent behind in a component. You will end up harming your replacement compressor as the oil will be damaged by the flushing agent.
Tim, any personal experience with the ProCooler sold by RennAire?
no I sure haven't.
