Post subject:  Waterless coolant

I need to change my coolant so I'm thinking of putting in waterless coolant - seems it has advantages - doesn't corrode and lasts a lifetime. Has anyone used waterless coolant in their bikes? Comments much appreciated.

No Phil but Ive thought about that before, I would be interested to know the outcome, it is meant to have a higher boiling point as well I think.
Wetter water or something like that

There seems to be lots of advantages - so much so, it makes me wonder why water based coolant is still used.

It boils at over 180C and freezes at -40 and doesn't vaporise so no pressure build up in the system. You can take the radiator cap off while hot and you won't get a face full of hot water and steam!

Have a look at the website with more info:

Well, if I don't get any adverse comments - I shall have a go and do the conversion. I'll let you know how it goes Brad.

There was an episode on Wheeler Dealers this week where they opted to use waterless coolant, and stated all the above positive points. They put it in a Triumph TR6 they were sorting.

It looks great stuff, but was pricey at £90, but as said it's a lifetime product and has some great benefits. He did however, have to remove all traces of existing water within the engine, using another product to flush it and a compressor to blow it through, think it took a week to get it ready prior to using the waterless coolant. So may be worth looking into what prep is needed?

Can you add rad weld to it if needs be in an emergency I wonder?

Found This on Evilbay - Evans Waterless Coolent £26.95 2L
http://www.ebay.co.uk/itm/PowerSport-R- ... SwnipWXBbu

It also recommends using Evans Prep fluid to purge remaining water / old coolant from the system

Prep Fluid £15.19 2L

Just a couple of examples, other brands are available, lol. It may be worth buying the 5L options and do a couple of bikes, and sharing the cost, as there's always a friend in need! :?

It all looks good, the only bit I could not see is if it had the same heat transfer properties?

It may boil at 180+ degress or what ever but I use Halfords pink.

Id rather know my bike was getting HOT rather than the liquid not letting me know because its not got to the boiling point.

Antifreeze....don't sweat it.

I assume but I may be wrong that the bike has a coolant temperature sensor set to a given temperature - say 100C which would still switch on the fan & warning light even if the coolant doesn't boil at 100C. I guess some bikes don't have temp. warning lights or fans so it would be difficult to spot overheating issue without having steam escaping from rad cap.

Thanks for the links Dominic, yes, I saw that Wheeler Dealers programme too - that's what gave me the idea. I've read the conversion notes and as you say, you have to drain all the water out.

In the conversion instructions they suggest introducing low pressure air to flush out the last dregs of water but they say, ' This is not absolutely necessary as the Prep Fluid will absorb any remaining water".

About leaving it for a week with the Prep Fluid they say. 'However if the engine to be converted has a predisposition to leak we recommend running the Prep Fluid for a week to verify system integrity.'

Don't know whether Rad Weld would work with the stuff and I have no idea what the heat transfer rate is - I would think that depends more on the coolant flow rate and radiator size - but I'm no engineer so I could be completely wrong. I see their publicity includes mention of Honda adopting Evans’ Power Cool 180 in the MX1 World Championship in their factory CRF450R.

I must say I'm getting more convinced the more I read and hear. Thanks for all your comments.

Good point - if temperature sensor was faulty - then the engine would heat up to 180C before waterless coolant boiled and let you know. Would the engine seize up at that temperature?
