MG MGA - WATERLESS COOLANT

When I wasn't stuck in the mud at Blenheim for MGB50 -(I think I was probably the only person driving a Y when I arrived just after 1.00 pm )and to dodge the rain visited some of the trade stands.

One of these was 'Evans Waterless Coolants'. It looks a very promising way of potentially overcoming the use of water in our cooling systems and avoids the use of anti-freeze, provides enhanced flow and can be reused.

It's not cheap and I wondered if any of our Y community had used/is using it. Experiences would be useful. I need to be assured that it is and does what is says on the can and fellow owners may well be able to help me if indeed they have used it.

Look forward to hearing from you!

Sincerely

Jay Leno's column in this month's issue of Octane magazine praises this stuff. He stated that it is $35/gallon. Jay is a car guy of course, but there were no details about the product.

I think it is closer to $100 a gallon over here. We did discuss it briefly a while back: It's in the archive under Evans Waterless Coolant.

No go for a vintage car with marginal cooling capacity. It is similar to running 100% glycol and no water.
Specific heat of water = 1.00
Specific heat of 50/50 = 0.81
Specific heat of Evans = 0.68
To make this work without changing the coolant temperature you need 20% more fluid flow, and the vintage car cooling system cannot do that. With boiling temperature of 369dF you don't need any pressure in the cooling system. Any claim of improved fuel economy comes only with higher operating temperature, and carburetor cars have a tough time with that a well.

Also, the thermal conductivity of organics is much lower than water.
