Anyone used Evan waterless coolant?

Morning all,

I've been doing some interneting, and after seeing a friend use it, I was wondering if anyone on here had used it before as well? As my bike does run hot (and I just hate hot bikes lol), with traffic etc, I think I'd like to give the Falco a early present

Not used it but when you say your Falco is running hot, how hot and at what sort of speeds.

Nothing silly, just 95'c and the fans kick in until she cools down (Slow speeds 30Mph and in traffic). But with the hot weather and the traffic always being awful, I thought I would do something to take the pressure of the internals and put my mind at ease.

That's completely normal, nothing to worry about at all. Engines are not exactly thermal efficient! that's why we have radiators and fans :P

I can't see any point. The fans kick in before the 100 degree boiling point of water based coolants so there would be no benefit in using a non water based coolant.

The engine and coolant temperature will still rise to roughly the same regardless of the type of coolant inside.

To actually make a difference to the engine/coolant temperature, you would have to fit either bigger/more radiator, fans, etc or make the fans come on earlier somehow.

I've no experience of it but there's a couple of guys on a BMW forum I use recommend it. I think it's supposed to be a lifetime fluid too so you shouldn't have to change it again.

Will exceed 100C before boiling as the coolant will raise the boiling point and also it's under pressure.
This is why it is dangerous to remove the radiator cap of a hot vehicle - you remove the pressure and it boils.

Good point.

Further backs up the idea that there is no point in using waterless coolant.

I have it in my Falco. I used to see 105° stuck in traffic days gone by and I worried about the coolant boiling out of critical areas in the water jackets. So I switched.

It is supposed to be a lifetime coolant, which is good thing as it is so damn expensive now.

as of right now, I was doing 40mph and the bike wasn't really cooling down to the high 70s/low 80s as normal. What is the bleeding, and this burbing

I keep hearing about? The bike did have too much coolant in the reserve, so I took some out and the cooling got worse. Should I just fill her back up?

I hear what you are saying, but if I never have to worry about the bike coolant again, I will be a happy man.

OK .... if you loose coolant - or just replace the coolant, it is possible to get an airlock in the hose that connects the top of the two radiators. "Burping" it is the act of squeezing the hose to force the air out of it. It's a bit of a PITA to get at it - you certainly need to remove the plastic trim between the 2 rads.

With you there

TBH I've been in 2 minds whether mine needs burping since my issue with the coolant leak I had a couple of weeks ago .... but with all this hot weather I'm not sure whether I've a bit of an issue or it's just that it is unusually hot at the moment. I'm waiting 'till the weather cools down a bit before doing anything (mine is cooling back down to temp when I find a bit of road where I can get up to 35 or so)

I think there is a coolant overflow pipe. If there is too much then it will automatically drain out. I wouldn't have thought it would be necessary to remove any from the coolant bottle.

I will have to do that tomorrow now as I haven't got time right now. I didn't replace the coolant today, I just removed the coolant to get back to the MAX level. is the bleeding valve/screw on the pump itself?

The bottom screw if memory serves...

If you don't yet have a workshop manual, you can download it from Martin Poll's website. Get the OCR one as it is searchable:

I fitted a lower temperature fan switch to mine. The fans come on at 84C.

Given we have summer days of +40C, I felt it would make a difference when stuck in traffic.

I also found that keeping the speed above 60km/hr helps a lot with keeping the engine cool(er).
