Deano1968 37 Report post Posted October 3, 2017 Hi. Just bought an E30 which is fitted with air con but it doesn't work. The last owner never used it. I'm assuming that at the very least the gas has leaked out. I have spoken to a few car air conditioning businesses and they tell me the only option is to upgrade the system to run R134a. Can someone tell me if this is my only option? I found the following article which suggests something different. http://www.rtsauto.com/how-to-recharge-the-ac-in-your-car-eg-used-will-be-e30-and-how-to-use-ac-manifold-gauges-and-pull-vacuum/ Cheers.

nick496 268 Report post Posted October 3, 2017 Hi Dean Originally E30s used r12, which as the article states is quite hard to aquire these days since it's been replaced with R134a for some time. If you are unable to track down a company that still has r12 in Stock, R134a is your only option Quote Share this post Link to post Share on other sites

actletpone 43 Report post Posted October 21, 2017 Interesting article, wonder if anyone sells r12a in nz? Quote Share this post Link to post Share on other sites
C-130 Hercules 571 Report post Posted October 22, 2017 Here is an article about it: http://www.coolcar.co.nz/all-about-air-conditioning/facts-about-your-vehicle-ac/ R12a won’t be available easily unless you find old stock. Possible to import r12 recharge kits but I am not sure how NZ Customs would feel about it. Suggest you check with them Quote Share this post Link to post Share on other sites
Olaf 3317 Report post Posted October 22, 2017 if it's not working it's probably leaking somewhere... going to the trouble of R12 only to release it into the atmosphere? Not environmentally sound really. R134a is the go. Quote Share this post Link to post Share on other sites
hotwire 352 Report post Posted October 23, 2017 Have done plenty of R12 - R134 retrofits. All i have ever done is evacuate the system, fit R134 retrofit adaptor ports (they screw on to the old R12 ports), pressure test, if good then replace the receiver/drier & attached o rings (not all the rest) vac down & regas with R134. Simple! May be cheating somewhat but it works fine. Quote Share this post Link to post Share on other sites
