[Healeys] Evans Waterless Coolant

[Oudesluys]

Forget Evans, expensive and no real advantages except that it won't boil 
when the engine overheats although this allows you to enter the danger 
zone. Cooling efficiency is far less than cheap premix coolant which can 
be topped up with water in an emergency. And when the coolant boils, you 
know instantly the engine overheats!!
Be careful though with the modern non (less) toxic red coolant in older 
engines. It may cause havoc with seals and gaskets and should only be 
used in modern cars. Use the (slightly) more toxic blue or green variant 
which is safe for older classic engines.
You cannot cure cooling problem by using Evans. You will have to find 
the cause and rectify it.
