Leaking Air Con

[Adge]

I have a leak of air con. refrigerant, probably up under the dashboard. The air con technician suggested using an air con equivalent of radseal as a first try at sealing the leak. This would save £450! if it worked. Has anyone else tried this route? Seems to make sense and avoid future leaks.
Thanks in anticipation.

surely an air con tech would have been able to tell you exactly what the prob is mate.

the refrigerant has a dye in it that glows under infered light....
if 20 or so gramms of refrigerant had leaked out there must be traces of it for him to see.

i dont know anyone thats used it im afraid.

on a side note... where on the white isle are ya ?
i grew up in Southampton and spent alot of time the rock.

The stuff works on small leaks. Units fitted to most modern A/C systems are made of chepo alloy and weep for a better word, if they are split badly then forget it, as posted leak detector as in gas will pick up a bad leak and maybe not a small one have another word with your A/C man, older Volvo systems are of a much better quality.

My 850 also has a leak behind the dash that my air-con bloke found by waving his 'sniffer' round the air-ducts. The leak is most likely the evapourator which looks like a small rad that lives in a very dark place behind the dash. It is not that dear on it's own but the labour to do it is quite high as it's a dash out job. He advised me against using a leak-stop type agent as he claims that it will over time it will damage the rest of the system.

Thanks "Nobananas", that's complicated what seemed like a simlpe solution.
He did say that the compressor might clog if it had to be removed for some reason. It seems exposure to the air on dismantling , which obviously is how the stuff works, can do more harm.
