Never heard of it before until Wheeler Dealers stuck it in a TR6

Any good?

Done tons of research on this myself, to make this coolant work properly cooling system needs redesigning with different pump flow rate etc. wink

It's not really required tbh something that may be of intrest to you is I know someone who is currently logging data on what differance water wetter can make to a charge cooler & its looking quite promising smile

Evans are the main people for it.

It is pretty expensive, and for a relatively mundane car with an already good cooling system there really isnt much point.

For an engine that is pushed hard or one where the cooling system is near it's limits then it can be a good addition though.

But to drain, flush and fill the system you'll be well into a few hundred quid.

I think most of us don't need it TBH. Just think if you get a hose problem & it gets dumped all over the road

Mustang man told me about water wetter it makes water wetter laugh I would of thought just running a higher content of anti freeze would have the same affect

It's some sort of chemical composition that helps with the transfer of heat, I heard of a while back but just thought it was another form of snake oil but the results so far are very promising

I ran in mine 70% anti freeze and according to the data logs I was running between 4 and 7 degrees cooler which was a good thing but the water wetter I've seen just looked and smelt like antifreeze

I once ran my Dolomite Sprint on 100% antifreeze and it ran very hot to the extent of boiling over, so I would guess any higher percentage than 50 would tend towards the same effect....

I've got some Evans here. As has been said it's not cheap. Two of my engines have a habit of rotting from the inside out, so cannot use water in the cooling system.

IIRC, the original RDLCs were 'LCs' because they needed to run hotter than a standard water/antifreeze system of the time would allow.

It just intrigued me when I saw it, even when they run the car up to temp and just took the rad cap off !

Any time Ive tried water wetter, it hasnt made a bit of difference.

Pure water is the best coolant ( Except for the Evans stuff of course )....but we must use some sort of anti-freeze and corrosion inhibitor otherwise water would be pretty useless lol.

If you're doing a fresh build and sure it will stay together then you can use the Evans without having to flush and prep the system so costs would be less. I think it's around £65 per gallon. Prep fluid is same price, although luckily the prep fluid is re-usable.
Probably until it gets saturated with water.

It doesnt freeze, it doesnt boil, and because of that it generates almost no pressure in the system which is a good thing.
But in use, temperatures will read slightly higher on the gauge. It's just down to how the fluid extracts heat from the engine faster though, so not actually anything to worry about.

That's weird ??? I used to race Midget speedway cars back in NZ and I ran that on 100% antifreeze which was around 10degrees lower than anything less??? Does this depend on the type of cooling system or is it hit and miss ???

Water wetter works by decreasing the surface tension of the water IIRC. It therefore allows better heat transfer. I have used this in race engines and it worked, period. Must remind myself to get some fitted to the TVS motor.

I used a product sold by a company called Radtec.

My Sprint used to overheat regardless -or the water pump would fail!

Antifreeze doesn't transfer heat away from the engine as quickly as water does, so if you use too high a concentration of antifreeze you're actually preventing the cooling system from working correctly. At least that's what I was always led to believe?

Same here, had to have the heater on full summer or winter to keep temps down lol, I do have a pic of mine with me standing next to it, not a good site to see lol think I was 18 lol
