Lankytim Posted March 3, 2015 Share Posted March 3, 2015 Hi all. I need to inflate my Allegrom very tight and don't want to buy any hydragas fluid. I do have quite a bit of concentrated screen wash though. Both fluids are alcohol based so could screenwash be used in place of hydragas fluid? I think screenwash is basically the same but with detergents added. Lankytim 1 Link to comment Share on other sites More sharing options...

Station Posted March 3, 2015 Share Posted March 3, 2015 The person that filled mine said it 'really was just antifreeze'. I'd try it out with concentrated screenwash though. Link to comment Share on other sites More sharing options...
STUNO Posted March 3, 2015 Share Posted March 3, 2015 Assuming that both fluids are the same, which for the amateur here seems unlikely, The detergent content may be a big problem. Personally I would avoid unless the system can later be drained and flushed. It sounds to me like a good idea that could go horribly wrong ! On the other hand you could end up with " float on bubbles" suspension. Link to comment Share on other sites More sharing options...
Richard Posted March 3, 2015 Share Posted March 3, 2015 I'm a bit tighter than you, I used to just use tap water. Christine 1 Link to comment Share on other sites More sharing options...

oldcars Posted March 3, 2015 Share Posted March 3, 2015 When it comes to hydragas it just has to be Heinz. Lankytim 1 Link to comment Share on other sites More sharing options...

dollywobbler Posted March 3, 2015 Share Posted March 3, 2015 I'm pretty sure that regular antifreeze can be used. Link to comment Share on other sites More sharing options...
UltraWomble Posted March 3, 2015 Share Posted March 3, 2015 Glycol antifreeze and distilled water was what I used on the 1300 and the Metro. No idea if that was correct but it worked.I wonder why BL displacers seem less inclined to go flat compared with Citroen ones? Ive junked amny spheres over the years due to them being flat and devoid of nitrogen, but BL displacers seem to have an unfeasably long lifespan (probably just as well really as they went out of production some 13 years ago) EDIT:Seems I wasnt far off the mark:http://www.hydragas.co.uk/technical.html49% alcohol49% distilled water1% triethanolamine phosphate1% sodium mercaptobenzothiazole Link to comment Share on other sites More sharing options...
Sigmund Fraud Posted March 3, 2015 Share Posted March 3, 2015 I had used neat ethylene glycol antifreeze to fill up my old Aggro. It worked fine, in fact the change in viscosity firmed up the damping and made the thing feel sporty* !!! Christine 1 Link to comment Share on other sites More sharing options...
vulgalour Posted March 3, 2015 Share Posted March 3, 2015 The 2% that isn't alcohol or water is just put in to stop youfs drinking it or something. I'm pretty sure I read somewhere that detergents should be avoided because the frothing isn't good for the system, if you get air in the Hydragas it gives a somewhat crashy ride. You definitely don't want your Allegro to ride like a modern BMW. UltraWomble 1 Link to comment Share on other sites More sharing options...
oman5 Posted March 4, 2015 Share Posted March 4, 2015 My allegro is running 50/50 antifreeze and water in its suspension. It's fine. DO NOT throw out any displacers that have gone hard, they can be re gassed now and they're getting very hard to find. Link to comment Share on other sites More sharing options...
sierraman Posted March 4, 2015 Share Posted March 4, 2015 Would using VO5 work? Or would a brand such as Timotei be better? Link to comment Share on other sites More sharing options...
