well as a matter of fact, I was just reading this and about to post it as a new thread...... Keith Calver article on cooling



http://www.minispares.com/Article.aspx?aid=90

I don't run ANY antifreeze/antiboil green crap in my engine, I don't bother, but some rust inhibitor would be nice.... I did run Redline Water Wetter once, and it did make a difference, but was a bit expensive.

i have a built in rust inhibitor system in my engine...


it grandually released small amounts of oil into the water, which is then conveniently realeased and burned off in the the combustion chamber..

Are you not confusing between premixed coolant such as you buy at the auto places in 5 litre tubs and the concentrate stuff sold in 1/2 litre containers that you mix with water to get the desired ratio.

The premixed coolant is supposedly mixed to its optimal ratio already and is ready to go in - cant see a reason to dilute it further. Whereas the concentrate should be mixed to the recomended ratio (10/1 water to coolant i think). So 40/60 seems like either way too much coolant concentrate or not enough premixed coolant.

I use destilled water and corrosion inhibitor. I never use glycol or chemical coolants.
I use distilled as it is less conductive, and has less suspended oxygen which reduces corrosion.

All ali bits just get eaten without inhibitor.

Water does not compress at all or cavitate as easily as coolant. Glycol/Chemical coolants compress and more easily cavitates so water pumps etc work harder.

So while coolant raise boiling/lower freezing they also are less effective at being moved around.

This especially true of high concentration mixes.

If boiling is only problem when your cooling system is working effectively in the first place.

what corrosion inhibitor do you use?

forgot the not - I do that.

I use the Castrol in the small can one. Forgotton the name.

This one

that sure is a smaaaaaal can..

reading through, question keeps popping up, as BIAM said, do people use distilled water when mixing with the coolant (corrosion inhibitor) ???? ive heard its much better, cause of less minerals than normal sceme water.

The main reason I use is that it is a poor conductor. So any stray current doesnt promote corrosion. My daily driver is an all aluminium engine so its little bit more sensitive to corrosion than an iron block/iron head engine.

I always thought aluminium corroded slower than iron due to Aluminium being so reactive. It's so reactive that in contact with air, as in when it was cast it will form a protective layer of aluminium oxide on the outside, proventing rust. I may be dreaming this al lup but that's simple chemistry. However two different metals (aluminium block mounted on an steel gearbox) can casue some really bad corrosion. Back to topic... I use coolant, pre-mixed. water will corrode my engine, the engine that came out of my car is destroyed in the water jacket due to last owner running water as he (or she) was too tight to use coolant or distilled water. Distilled water doesn't conduct electricity at all. It doesn't contain ions. But tap water does. - Just thought I'd add that.

Ignore this Im on drugs not relaly jsut was 1/2 asleep and not really listening to the question......of course Im using diluted collant ......don't mind me yesterday I was all shades of ****** up.....

Thanks for corecting me Mike, and yes I use diluted coolant 10/1 and no I don't ever have a heating problem only when I have busted or cracked hoses...... gawd Im a idiot!

so whats the difference between say techtaloy 60 and techtaloy 100 ? obviously its stronger.. but whats stronger ?

the concentration of whatever the additive is. Should be on the label.

I flushed the coolant system yesterday and put in a corrosion inhibitor (actually the one BIAM has a pic of see above) The engine didnt have too much sludge or anything in it so i hope i got to it in time!

I drove the car about 95 mile over the last two days and it has made a difference to the running temperature as it didnt get over 90 at any stage whereas it did before probably more caused by flushing the system.

Thanks for all your help,

Matt
