Waterless coolant

[jonbuoy]

It would seem that many F1 teams are still running water based coolant but there is an FAA recommendation to run waterless coolant running some Rotax engines - but this is just to avoid a possible loss of coolant if the engine starts to overheat rather than actually offering more heat transfer in the first place. Its like the Synthetic vs Mineral oil debate - some will swear by it some will swear at it.

I like the idea of not having to pressurise the cooling system - less chance of blowing seals, hoses or water pump leaks. The engine I have has known corrosion problems in water ways so thats a bonus too.

Would be nice to see two tests on an engine dyno with readouts for oil temp and cylinder head temps. If it does prevent steam pockets around the cylinder head this won´t show up just measuring block or coolant fluid temps.

Just collect a bunch of engine oil from oil changes, then tip it in once you enough. Sure to work, right?

Bang some fucking 80W/90 gear oil it,
Bigger numbers mean it should work right?


Just put 100% Glycol in the bitch and be done with it.

The waterless coolant I am looking at does not boil so that shouldn't need a reservoir filled with fluid and overflow hose etc = weight saving reasonably cheap.
Only a thought, I'm no physicist so I may be wrong.
