From: Dave Plowman (News) on 23 May 2010 05:11 I've read that a lot of modern anti-freeze isn't suitable for classics or older cars - it attacks the copper rads, etc. But mine has an ally engine so needs an anti-freeze all year round to prevent corrosion. Anyone know which brands are suitable? -- *'Progress' and 'Change' are not synonyms. Dave Plowman dave(a)davenoise.co.uk London SW To e-mail, change noise into sound.

I used to use Bluecol in my Imp when I owned one, which is also an ally engine. I have no idea whether the formula has changed since though - I am still using the rest of the stock I bought at the time. You could check with the manufacturer http://www.bluecol.co.uk/index.cfm?page=1 Bluecol is still available, though a bit difficult to find on the shelf. One of these might be convenient for you. http://www.akautospares.co.uk/brands/Bluecol.html http://www.eurocarparts.com/ecp/p/Accessories/Winter-Essentials/Anti-Freeze/Blue-Anti-Freeze/?523770262&0&cc5_700 http://classicsagogo.co.uk/acatalog/Antifreeze.html http://www.carstorz.co.uk/bluecol-car-anti-freeze-protection-84-p.asp Jim

Perhaps called 'classic'? What I've seen of it suggests not - since it seems to have a longer life these days. -- *Remember: First you pillage, then you burn.

Anyone know > which brands are suitable? Not to hot on brands, but what you need, I think is "inhibited propylene glycol" antifreeze. IIRC the current antifreeze sold for most cars is buffered to be slightly alkaline. The inhibited glycol is buffered to be neutral and does not corrode copper or aluminium. This antifreeze is usually sold as a 90% solution which needs diluting 50:50 with water to give year-round protection. It's available for domestic heating systems and is usually pink in colour (to distinguish it from the blue/green colour of other antifreeze mixtures). Obviously you mustn't mix the two. The antifreeze that most classic were originally filled with was, BTW, absolute rubbish. To get costs down a glycol/methanol mixture was used. It didn't last long, and tended to accelerate corrosion. This page gives a specification for the inhibited PG antifreeze: http://glycolantifreeze.com/ And this page promises to have some available "in May" http://cc.derekharris.com/index.html
