Wetter water

[V6GTO]

I've seen a product advertised that is an aditive you put in the coolant. They claim by making the water wetter, releasing surface tention, it improves heat transfer and so makes the cooling system run cooler.

Has anyone tried it? What's the verdict?

I sell this stuff .. not so much for it's water wetting properties for heat transfer (tho i've no doubt it actually does do this) but it's great for chasing air pockets out of cooling systems .. it lowers the surface tension of the water and is great for bleeding air from difficult systems.

I have used it and yes it does work

somehow it allows the water to carry more heat then before

I use it in the Chimaera... and it's worth it.

As with all these things, it wont solve a knackered cooling system / radiator, but it will helpthe system out.
