ZMANALEX Posted November 5, 2010 Share Posted November 5, 2010 What is the purpose of the H & L caps/valves under the bonnet/ Also ive seen gas recharge kits on ebay and are they worth it does any one know? Jed, the H and L stands for High and Low. The caps are in fact valve covers, and simply screw off to access the valves. I have never tried the Ebay recharge kits so I can not give you an informed opinion off them but I quess that they could be a waste of your hard earned. Alex.

Neilp Posted November 6, 2010 Share Posted November 6, 2010 If u over charge u will destroy the compressor. The kits may be ok but better go to halfords or another motor factors shop and get one with the added insurance if there's any problems with it. If you charge urself and break the system then you have no comeback either. Quote Link to comment Share on other sites More sharing options...

Darren-B Posted November 6, 2010 Share Posted November 6, 2010 you may aswell get someone local to you to regas it, there not really expensive, I got my van done for £50 a while back. Then if it goes bang you have some comeback Quote Link to comment Share on other sites More sharing options...
Ricey Posted November 6, 2010 Share Posted November 6, 2010 I remember reading somewhere a while back that you have to be particularly careful regassing aircon.....apparently (and this could of been some chimp peddling an urban legend) if you purge any of the aircon gas it decomposes into something very close to mustard gas. Although I'm sure some air con expert will now reduce me to dust for suggesting such a thing Quote Link to comment Share on other sites More sharing options...
Darren-B Posted November 7, 2010 Share Posted November 7, 2010 I personally haven`t a clue, perhaps you should try inhaling some, you never know it may contain Nitrogen Quote Link to comment Share on other sites More sharing options...
Neilp Posted November 7, 2010 Share Posted November 7, 2010 I'm an ac engineer but not for auto. The principles are all the same though. Air psychrometry is the same no matter. My advise is to find an auto ac engineer. Not kwikfit etc. Find a private company who know what try are doing. It will save u the heartache of destroying a compressor Quote Link to comment Share on other sites More sharing options...
