Hi- has any Triumph owner tried Evans Classic waterless coolant? If so, what are your thoughts-thanks.

Been discussed a number of times. Do a search on all the Triumph forums here, not just Herald/vitesse.

Hi Andy- yes I've put Evan's in a few cars. the system must be as dry as possible- so wash out well with water and try to dry out thoroughly. Evan's sells a rinsing product or use some of their coolant and drain it out to discard.

Nice to have a lifetime coolant and not worry about water becoming corrosive, BUT, consider that if your car overheats it will not boil. If you are not minding the instruments and don't smell the car getting hot you can cook a motor without it boiling over.

So- I haven't decided if I want it in my street cars, I've only put it into museum cars which get limited running and where preservation is the priority.

Best- Kevin

I was asking this just the other week at a car show with some Jaguar guys.
Apparently it is FAR worse than regular coolant if it gets in your engine oil.

I used Evans in a Reynard Formula Ford with a Ford 1600 cross flow. It worked great, but we only used it because it let us run with smaller radiators than with a water based system. As I recall temps were about 250F. I caution that it is very poisonous and expensive. I know some guys run it on the street but I see little if any value in doing so.

If I recall correctly Evans ran a Camaro in SCCA that employed some thermal expansion properties to circulate coolant instead of a traditional water pump. It had a trade name something like HydroSiphon or some such.

Hi- I switched to Evans & car is running great. Took her out for good drive last weekend & really impressed with this stuff. Won't be going back to water based coolant.

Here's a photo of my Vitesse Mk2 engine. Noticed after a long run (on hot day)-when I switch engine off there is no metallic cooling sounds-just very quiet engine bay!

I put it into my spitfire when I put the new alloy radiator and electric fans in. I used their flush first. The main reason I put it in was for the longer term benefits ie less corrosion inside the engine. I'm not sure if there are any rubber seals in our engines but its supposedly better for them too.
