bollocks.
its a pressurised cooling system, 1.4 bar peak release pressure, boiling point at that pressure of plain water is 128 degrees, proper coolant will be a little higher again.
just seen poodles post before mine witch is plausible as I have struggled to find figures myself
, I said nothing about the water boiling I was just simply talking about the block and head being at over 100 degs which I think is very hot for a engine and wouldn't want to run one at that temperature ever on 14+ year old aluminium head and gasket!
