i am not stupid always ran 50/50 or 60/40 but i was going to buy some pink stuff and my broher pointed out i should buy blue only for my block and gave me a couple of reasons which i can not remember top of my head but general crack was blue for older cars newer ones pink or green not saying that is in every case.

i know just making a point referring to people putting just 100% water in. someone i know did it and i know a garage that did it to someone never told them they expected it was all done when the new rad was fitted both found out the hard way in winter. must admit though i thought the colours were just different manufacturers using die to make there product stand out until it was pointed out to me

Only time ive seen green is when ive done water pumps on civic ek9's that hadnt been worked on in uk. Thought the green was a jap thing.

When you say green, do you mean that flourescent yellowy/green stuff? I was using that in my cars 20 odd years ago. I thought it was just uniparts colour of choice.

Any body any thoughts on the MOTUL INUGEL OPTIMAL http://www.opieoils.co.uk/p-903-motul-inugel-optimal-ready-to-use-cooling-liquid-anti-corrosion-and-anti-freeze.aspx

I
t doesnt require mixing with water and is apparently very good
Haven't we done this one already in the "Oil advice" thread?

That's what I use, and I've never had any problems with it; I'm not thrashing my car on the track, and nor do I live in near-arctic conditions. I just found it easy to buy the stuff and fill the system up without messing around mixing it myself.

With regards to the colours; that's telling you what kind of coolant it is (there are some which are incompatible). I'm pretty sure that you just want "organic based" which means glycol; the silicate/phosphate/etc corrosion inhibitors are for things like plant machinery... and possibly some American cars.

Not really. I remember the bloke flogging it saying its good stuff, and you saying your sure it what you've used but iv asked for people opinions on using this stuff not the pobodyoc, I guess i should be a little more specific and ask those who do hill climbs and trackdays what coolant they use

As far as im aware you've never driven your car on track or know how to change a brake hose so your opinion to me means 'shit' me

LOL, just buy deionised water and antifreeze and mix it to whatever % you want, it's the same as the premade stuff..............an opinion of someone who rags the shit out of every toy owned

I'll be quite honest, and say that I've always worried about the wisdom of using deionised water in the radiator; it's one of the reasons that I started buying pre-mixed.

The logic is as simple as this: If you take all the ions out of the water, it really wants to put them back in again. If they only source of those ions is the metal in your block, that's what it will eat into to take them. - My head tells me that's why you're adding corrosion inhibitor rather than just pure ethylene glycol, but my heart says that if I'd never put deionised water in one of my instruments (even with Scania antifreeze) I shouldn't put it in my engine either. The manufacturer's instructions say 50/50 tap water with deionised... and since I didn't know how much coolant I'd be adding, I just thought it was easier to buy pre-mixed from someone who'd already though about that kind of thing.

Isn't the process of irons getting into the water one of galvanic corrosion? My thoughts are other than deionised water being non conductive, and also containing no impurities such as chalk/lime etc found in tap water it stands much less of a chance to cause any problems especially with anti-freeze also mixed in.

I'm not entirely sure... but makes sense to me, and does keep things looking cleaner imo.

i would have agreed with above but there again im no chemist lol
de-ionised water or melted snow/ice (if your a tight ass) is pure from oxidants so mix that with one type of a-freeze and youll be fine. its only when people mix different kinds of anti-freeze or use none at all that you can end up having problems
