Waterless coolant

[superjackal]

Anyone using waterless coolant in their bike? Any good?

Ok I have to ask. Given the cost and thermal density of water why would anybody not want to use it?

[bogan]

My GN had that; well, unless it was raining.

Exactly - my old Triumph has been using waterless cooling for quite some time and has not boiled over yet.

You could just give a clue as to the bike your are posting about in your initial post.
If you have an aircooled bike you use the coolant the bike is designed for so why would you not do the same from a water cooled bike? I go with Flip's remarks, why pay for something you have a free alternative for and apart from that your bike is designed based on the free stuff.

Well in terms of a topical p/t, I can't see me topping that, so yes, it would be well advised :bleh:

If you ask the mods nicely they might be able to change your username to 'Kwackal' or 'Erwackal' for example.

Indeed, post in Site Stuff...

I can see its merits in a modern lossless engine cooling system where its been used from new and unless you need a major repair you won´t ever need to touch the cooling system or flush again. As I understand it you have to make sure the cooling system is completely free of waterbased coolant before you use it as it won´t mix with water - you also can´t top up with water if you get a leak on a long trip.

That must be a piss take,


"Water - great for drinking but not ideal for engine cooling"

Water absorbs heat rapidly and dissipates heat just as fast.



"Engines filled with Evans usually run 3 - 10ºC hotter than those using water-based coolants"

Its flammable, slippery and doesnt evaporate if you spill it mmm sounding less and less like a good idea. I´ve been toying with using it on an engine build I´m doing - not so sure now.

Look at it this way,

if they use a water based coolant in race vehicles, heavy machinery and on highway trucks,
Its a safe bet to say it is probably the best thing to use.

I can see the merits - F1 and some other motorsports are using similar technology - ie waterless.

[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? :innocent:

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 oldstuff]

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.
