Evans coolant

[Fourdy]

I am considering the use of Evans coolant (waterless). Studied it for a bit. Jay Leno has used it in one of his cars for 16 years and states he has never had any trouble with it.

Has anyone of you had personal experience with the product. Meaning actually used it? Results? This would be used in my blown 276 with new 4 row Brassworks radiator.

Snake oil or ?

Thanks

I'm also considering it. If I already had antifreeze in my system I don't think it would be worh the time to drain it and flush it out in order to use the Evans, but my system is totally clean and dry. So starting from scratch I can go eithr way.

Had it in my Hi Boy which until recently ran hot.The Evans worked well but I was using it as a bandade to cover up a problem.It is expensive and really not needed if your cooling system is up to snuf .But this is just my opinion .Phil

Don't bother, if this stuff will make the difference between overheating or not, you have a cooling system issue.
I sell it at work, should say ,people buy it from me cause they think it's gota be good. Can't ever top it up with water without afterwards draining and flushing and conditioning the system to refill with the Evans.
Use a good anti freeze/summer coolant with rust inhibitors, and your golden, and more money in your pocket.

Leno has lots of cars and it makes one wonder why he only uses it in one car. Everyone I knew that used it eventually fixed the real problem(usually a plugged radiator) and returned to regular coolant.

I've have it in my other hot rod (non Ford). Been in there 15+ years. Never have done anything to it.

I think you'll find that's called a street rod, a hot rod has tools in back and a flathead in front.

Seriously, I can get it free, I won't use it. I work on a bunch of cars with it in. I have never seen an appreciable temperature difference with it. Like I said earlier, if this stuff "cures" an overheating problem, you have a cooling system issue that needs addressing.
Bloody stings when you get it in a cut! And damn slippery on the floor.
This is my opinion based on experience of with and without on a number of different autos, be they a humble Morris Minor or an E type Jag.

As I understand it, the main difference with Evans coolant is that its boiling point is 375F.
As others have said, if your flathead won't run under normal conditions without boiling over on water, there is something wrong with it. Masking this situation with a coolant that won't boil until 375F doesn't solve the problem and might even result in additional damage. Better to optimize your cooling system and run a regular coolant mix. But that's just my opinion.

I found a posting online by No-rosion that after studies posted the following. I have passed this on to Evans and asked them to comment back to me on the findings.

No-rosion - - -
SUMMARY OF FINDINGS
Conversion costs of $259 if you do it yourself, or over $400 if you pay a shop to do it.
97%+ removal of all previous coolant is mandatory in order to prevent corrosion.
Inhibitor deposition occurs on aluminum surfaces, which could cause issues in some radiators.
Engines run 115-140oF hotter (at the cylinder heads) with Evans products.
Stabilized coolant temps are increased by 31-48oF, versus straight water with No-Rosion.
Reprogramming ECU fan temp settings is mandatory to prevent the fan from running continuously.
Specific heat capacity of Evans waterless products ranges from 0.64 to 0.68, or about half that of water.
Engine octane requirement is increased by 5-7 numbers.
Computerized ignition must retard engine timing by 8-10o to prevent trace knock.
Engine horsepower is reduced by 4-5%.
Accelerated recession of non-hardened valve seats in older engines is possible, due to brinelling.
Viscosity is 3-4 times higher than what OEM water pumps are rated to accommodate.
Coolant flow rate through radiator tubes is reduced by 20-25% due to the higher viscosity.
Race tracks prohibit Evans products because they are flammable and slippery when spilled.

Tried it once in my 1913 Model T never again- ran way hot. The supplier did say to me when I complained that it "doesn't seem to work well in thermosiphon engines" -Karl

Thank you for your comments and research. Will not ever give a second thought. Good old H2O & No Rosion, except for winter, if not drained and stored.

You might consider a rust inhibitor.

Hi Fourdy, Please keep us posted on their response. I went to their website this morning and don't recall them mentioning any of the unpleasant side effects you quoted.

Do you really think a company would point out the negative effects of its product on its website? That'd be like Coca-Cola pointing out that cavities are more likely to occur when you drink soda because of the sugar it contains. Not gonna happen.

I'd be really surprised if Evans confirms or even responds to any of the No-Rosion claims.

[Fourdy]

Sorry, noticed I hadn't reported back. I have not received any comment back from Evans.

I put it in a 34 Packard at the customer's request. After a few weeks of just water and no leaks or over temp conditions he wanted it in there. I was surprised at how many hose leaks developed. Seemed to want to creep out behind the water pump retaining ring that has a copper compression gasket. Once that was all good we drove it, got it hot once more (about 170) then parked it overnight. Imagine our surprise to find it ate through the Permatex Aviation Sealant in the lower radiator neck on the block. I hate it also for the reasons stated above as in slippery and miserable to work with. Each repair required a total drain of the system. Snake oil? Yeah, a Black Mamba snake too...

Thanks for all the input. I will be going sana Evans.
