Old school non-permanent antifreeze there. How often do you have to add alcohol to the radiator to keep the freeze protection in place? Evan Williams in the cooling system has got to be more expensive than Evans!

So, here is some good news in general for Evans customers (the *non*-drinkable kind ). Evans offers *free* sampling for their coolant. Just send in 8 ounces with type of coolant, history (including whether the system was pressurized or not), and contact information.
By the way, in case there is any question about pressurization or not, Evans is now recommending a closed coolant system just like it was OE.
Companies whom back their product like that get an 'A' in my book
With that kind of manufacturer commitment, perhaps Leroy wants to pick-up where Lubrication Specialists left off?

While running EVANS™ w/zero pressure cap on accumulator I’ve never had water absorb into EVANS™ coolant according to readings w/refractometer. I suspect the reason is that there is more than enough temperature rise within the 6.5td cylinder heads too steam off any water that is absorbed into the cooling system.
Later 6.5td & LS series engine cooling systems w/accumulators incorporate steam vent lines while traditional recovery tank cooling systems do not. Steamed water droplets eventually finds its way to the accumulator tank where it would vent when zero pressure cap is used however using a pressure cap question is will the water that steamed be reabsorbed into the EVANS before venting occurs?

Unless I am missing something, even a 'sealed' OE system is not purely sealed as the cap will bleed-off excess pressure (actual pressure depends on the cap) and allow inhaling when the system cools. Evidence of this is the fluid level rise within the surge / accumulation tank when the motor is warm (versus the level when cold) and that the hoses do not collapse when the motor cools. Sure, some of the level rise is from pure expansion of a warmer liquid, but at some point the cap is going to let some gas lose.
So, this breathing even in a 'sealed' system will still allow venting.

I disagree with the "OEM pressurize the system" flip-flop. Half the reason I installed this was for a zero pressure system. The water pump does produce pressure regardless - But reduce RPM or stop engine takes pressure to 0. The heat expansion in a large system will bring the pressure up to the cap vent pressure and raise the overflow bottle level. "No boiling" of the Evans appears to reduce pressure in theory and maybe someone's tested that. At 375 degrees, well, the engine oil starts to give it up way before that.
Their website doesn't address the surge tank or overflow bottle moisture question.

Don't shoot the messenger Agree that the 'zero-pressure' aspect was a strong sales point to me as well. Would help if there was a FAQ that addressed the original reason for zero-pressure and then revision to closed system.
Worst case is that we can send a sample and see whether the open system is having an effect on coolant health

Use a refactor meter reading of 3% & under is good. I have an old email from their tech dept "I asked if I needed to add water 'say because I was somewhere remote had a leak fixed it and added water' do I need all new EVANS or can I remove the water by boiling it off at a later time then just add enough EVANS to fill system? Response, "water can be removed from EVANS by removing it from cooling system and boiling off the water" haven't tried this because never had a leak or excessive water show on meter.Don't shoot the messenger

@JayTheCPA just wondering what Evans is thinking. No ammo being wasted here...
Not to steep on anyone's feelings here but maybe this is being over thunk just a little
Evans is a widely used product in the trucking field, racing, and highway driving... in everything from daily drivers to 4 wheeler's and farm tractors..
It is pricey, but what top of the line type product isn't.
It is designed to do certain things that water based products can't come close to.
About 75% of people that herd about "ceramic coatings" 10 years ago put them in the "BS" file and dismissed any attempt to be tough the "new tech".. Waterless coolant falls into this category ..
Waterless coolant has it's place just like coatings, is it for everyone, naw, does it have some draw backs, yep everything does..
As for the notion of weather to pressurize the system or not.. why do ya need pressure in a cooling system, a water based system does for obvious reasons... has ANY auto maker that claims ell effects due to a water pump causing this and that tested anything other than water based coolant.... maybe, I haven't seen it, if so please link it so I can see the findings..
I run Evans in everything I own, tractors, trucks, cars, and I have never pressurized the system's, I don't need the system pushing on the internals of the motors or system..
The thought that a system with Evans will some how gain moisture and harm something... to me... is funny, if your motor doesn't get hot enough to boil moisture away then you have a little more to worry about me thinks...
As for Evans causing a fire, well I don't know, my stuff cranks easy enough not to need to waste electricity to coax it to crank.. so I have no thoughts about that part good or bad...
All this is just my thoughts and doesn't mean squat to anyone, just me wondering what else can be thunk up to debate...

Yeah, I have to be fair and admit I have a biased opinion against it because I know 2 people that got burned (literally) from it. There are many advantages to it. I wish I could justify the use of it in my hummer.
