CarlC Posted September 1, 2006 Report Share Posted September 1, 2006 My car's never had aircon since I've bought it. Not a great fan anyway of aircon and I would rather have the roof off and windows down being a sunny day driver. Also my S4 requires the old type R413 gas . So Im strongly considering switching the use of the rad to the CC (as per S300) and I have a couple of queries after studying the diagrams reading up on the aircon stuff. I also want to clear a few points up too? 1- Is there a direct gas replacement I can use to recharge my aircon without dicking about changing compressors, pipes for the enviromentally friendly stuff ? 2- On the combined Aircon/CC rad, am I right in believing the rear rad is for the air con ? 3- Looking at the parts manual for the S300 CC rad setup surely it would be more efficent to avoid the use of the T junctions on the flow and return to join the front and rear rads and instead have 1 continuous flow through both rads. This would maintain steady pressure right through the system rather than dropping pressure at the T which allows cc coolant to flow through the Aircon rad? 4- If I ever want to re-instate the aircon rad would I have caused any permenent damadge ? Any responses greatly recieved. Quote Link to comment Share on other sites More sharing options...
