Timmyb Posted March 5, 2016 Share Posted March 5, 2016 I have an ecowind diesel air conditioner fitted to my truck, http://www.lesliesauto.com.au/pdf/Ecowind%20Brochure.pdf over the past 18months it has lost its gas about 4 times. It keeps going back and they say they hey find something but only for it to happen again. They also told me they have filled it with nitrogen and left it for 24 hrs and there was no drop in pressure. Is there a dye you can add to the system and it shows up with a certain type of light once it has leaked out? any thoughts? they also said it could be he Tx valve? Would that cause the same symptoms as low gas? Quote Link to comment Share on other sites More sharing options...
mrsmackpaul Posted March 5, 2016 Share Posted March 5, 2016 when it gets re gassed do they put dye in it so you can see were its leaking out with a infer red light ???? that way you can see were the leak is no matter how small Paul Quote Link to comment Share on other sites More sharing options...
Timmyb Posted March 5, 2016 Author Share Posted March 5, 2016 Hi Paul. Nah, these guys haven't done the dye yet. I think in this case the dye would work well. It takes a few months to lose gas so it more than likely wouldn't show up in 24hr leak test. Quote Link to comment Share on other sites More sharing options...
mrsmackpaul Posted March 5, 2016 Share Posted March 5, 2016 I am amazed they havent put dye thru that is sort of standard thing out here even in a new system a lot of the time people put dye just encase this type of thing happens it takes you straight to the problem They can put dye into the system at any stage even now your local aircon bloke should be able to add it and at least you will know for next time Paul Quote Link to comment Share on other sites More sharing options...
theakerstwo Posted March 5, 2016 Share Posted March 5, 2016 But if its still under warranty you need to ask before you add dye.Sanden will not pay a claim if you send in a compressor with dye in it. Quote glenn akers Link to comment Share on other sites More sharing options...
tjc transport Posted March 5, 2016 Share Posted March 5, 2016 a small can of dye added to the system will allow then to look at each connection with a infrared light to find the leak, some dyes will show with a black light. i use a "sniffer" too. took me 3 years to find the leak in my crown vic, the schrader valve in the high pressure side connector had a chip in the rubber and it would not seal properly 1 Quote when you are up to your armpits in alligators, it is hard to remember you only came in to drain the swamp..

41chevy Posted March 6, 2016 Share Posted March 6, 2016 Dye check and or a sniffer is your best shot. I personally would start at the weakest point, the schrader valves like TJC mentioned. Start by snugging them up and check with the sniffer. R-12 or R133 is a "heavy gas" so check around and below the valves and fittings, Paul Quote "OPERTUNITY IS MISSED BY MOST PEOPLE BECAUSE IT IS DRESSED IN OVERALLS AND LOOKS LIKE WORK" Thomas Edison “Life’s journey is not to arrive at the grave safely, in a well preserved body, but rather to skid in sideways, totally worn out, shouting ‘Holy shit, what a ride!’” P.T.CHESHIRE Link to comment Share on other sites More sharing options...
