Uprated Aluminium Radiator

I'm not sure why the major guys don't use it my guess is that when they go into jiffy lube the guy would top the rad off and ruin the Evans. You can only have 2% water. A lot of Big rigs run it too and you only put it in once for the lifetime of the engine. plus you don't have that constant pressure on the system.

so do you run straight water in your cars?

Waterless may not boil over but you WILL run higher stabilised temperatures compared to water.
Specific heat capacity of waterless is around 0.64 in other words about half that of water.
If this stuff were any good it would be used by OEM as standard.

It is flammable, perhaps the cost of mitigating this is not worth it, also you're reducing the efficiency by running hotter so your detonation point will be 5 - 6 octane points lower meaning you either have to use higher octane gas or adjust ignition to suit and lose some power.
The plus point here maybe emissions could fall for the above reasons.

To be fair I kinda get why you would use it for vintage motors, Just not on a performance or race application, especially race, I believe this stuff if spilled has the effect of turning tarmac into an ice rink.

So now 12 months in and over 3000 miles using this stuff - no overheating or performance issues and it didnt flare up when i threw it into the fire, oh and no corrosion - and so what if you spill it - what happens if you spill oil - so 2 opposing views, pay your money and make your choice - I'm happy using it - in fact it worked particularly well in dissipating heat in my Skyline Turbo GTR - oh and you never have to change it or check your anti-freeze is effective - did I mention no corrosion or sludge

I'm an Evans distributor so believe me or not is your choice.

We have done plenty of conversions now and we, and our customers, are very happy with the results.

• We have had very few cars that run slightly higher temps but most don't.
• It will not solve cooling issues.
• The fact it boils at a much higher temp does mean that if your cooling issues are related to hot spots then the coolant will not boil and produce steam/vapour at that point. A water based coolant will and as soon as it does the hot spot is no longer being cooled so gets even hotter with a resultant snowball effect.
• It does not improve horsepower as claimed by Evans.
• A real benefit in my mind is the fact the system does not pressurise so all your hoses should last much longer as well as things like water pump seals. Below is a link to a video we did on our rolling road. When the car is up to full chat that’s me walking in and taking the rad cap off.

• It’s pretty much fit and forget as it does not need changing. It is also claimed that some users have removed it from a car they are selling and put it in their next car. Bit of a faff if you ask me.

Think you can tell we like it.

I'm running it on a 351 Cleveland and a 327 Corvette engine, prior to the installation I had to watch the temps as both cars would boil, now no boil at all. I have not noticed a higher temp, but a lower temp and it's taken a lot of stress away knowing I'm not going to boil over. I have dropped it onto concrete but it does nothing, I just wipe it up.

First excuse me for my rusty English.

My can am have fitted Evans fluid and works better of all my previous cars and so mutch constant...

I think as previously mentioned the problem with traditional liquid is the air lock... boil zones... and this influence the right cooling flow.

Someone have say "engine work hotter" but if your thermostat work well engine temps rest normal like with glicole liquid.

Used Evans NPG in mine since 2005 IIRC (I really can’t remember exactly when I put it in..)... To start with I ran with the thermostat out and was also was aware that I might run hotter, especially as I have the older 'sport' rad, so I put a thermostatically controlled oil cooler in as well - just in case (and because I wanted to...).
In the end I put the thermostat back in so it would warm up faster, yes it can run hotter but I never really had a problem, It sometime went north of 100 degrees but only after a very spirited drive and a failure to put the fan override on. Never noted a problem with the engine and the oil never got too hot (more than 110 - which is my benchmark). Just never really had to worry about it.
I have replaced the water pump pulley with a smaller diameter serpentine March conversion as it is seen as better practise to run the pump faster (with the older formulation of NPG I have), but again it was more for the sake of buying something new and shiny rather than need….
I have taken it out and reused it a couple of times over the years and It has changed colour a bit, but other than that I have noted no difference…
Thumbs up from me… (for what its worth..)

As in the thread no mention of the product name, no suprises as written by a journalist and they wouldn't want to have to justify/substantiate their comments in a court of law - says it all - I dont know of a single person who has used Evans waterless coolant to the detriment of his car.

Do you Steve ?

Don't know of any but there is the possibility based on temp.
Because the Evans boils at a much higher temperature it is possible an engine could be damaged at that temp. For instance, it is said that the Rover V8 with steel liners in an ali block could suffer liner slip at those temps as the liners are assembled by heating the block and perhaps cooling the liners. Water based coolant would have boiled earlier and given more warning however something has already gone badly wrong for the Evan to have reached boiling anyway.

Yea and a meteorite could kill you in your sleep, people using Evans are going to be much more observant than the average guy. But heywhy not just use straight water it cools better than any other liquid and it warns you much sooner.
