Putting a new engine together, so been thinking about which coolant to use. If I choose Evans now's the time to use it before using water in the system.
-
I use water wetter and distilled water. There is also an additive from Cat that you can use that is cheaper than the others, probably the same thing. Sorry - don't have a part number.
-
I would use Evans in a diesel where I'm looking to retain cylinder heat by running super high water temps.
I have no experience in it with a gas engine, but it seems like it would promote detonation.
-
I asked a Ford guy running it in a small block 302. He was happy with it, only thing he changed was the water pump from a stamped steel to one with a curved blade cast iron impeller.
-
I have Newer had any problems with just half tapwater half antifreece
but on the other hand we got wery clean tapwater here no lime or iron
or clorine and seldom over 86 degrees in summer
-
I've tried it, hated it. Seemed like it took longer to heat up but took forever to cool back down. Save your money.

You can buy material that is chemically very similar by going to a furnace supply and buying the fluid that is used in radiant floors. I believe it is propylene glycol. The molecule has one more carbon atom than the regular ethylene glycol found in antifreeze and seems to have a greater ability to carry/transfer heat. You need to use the proper components in your cooling system to take advantage of its properties. If you go to the Evans website there is a lot of information, at least the last time I looked. You need a different radiator with much larger tubes, as an example.

Napa carries a brand of anti-freeze with propylene glycol. It used to be called Sierra, now its Prestone Low Tox. A few dollars more than regular anti-freeze. Use it like regular anti-freeze mixed with water. Don't have to change any components in the cooling system.
Nascar uses the propylene stuff. Never did figure if drag racing tracks would allow it. It may have advantages with being more flame-proof. Regular anti-freeze has a high ignition temperature, but then burns fast and hot.
The propylene is non-toxic except for the additives used in the coolant. They actually use this stuff in food, like Mountain Dew. Its a lot safer for pets. I think it is slightly less efficient than regular anti-freeze. A little more viscous.
I've tried this new stuff in an old car for quite a few years and it seems to work OK.
Sometime this year or last year a law was changed and regular anti-freeze was supposed to get added bitterness chemicals to deter animals and pets from eating it.

>seldom over 86 degrees in summer
Here, itt's seldom over 106 degrees in the summer. 8)

Where I worked on refer units with small diesel engines driving the compressor, at one time testing Evans coolant as a possible replacement for ethylene glycol based coolant. Looking through some notes from the chemist. Most of the Evans was propylene glycol. The reason it was considered is it did not contain phosphates or silicates. Europe had ruled out phosphates and China ruled out silicates in engine coolants, so it was tested. The Evans never received engineering approval. One problem noted was the viscosity of the Evans reduced the coolant flow rate about 20% at the operating load of engine, (in this case a 4 cylinder Kubota diesel) and reduced heat transfer to the radiator. So the conclusions were a radiator of larger capacity and a higher flow water pump would be required for use. The decision on coolant at that time was to go with Dexcool, which ended up with that mess of corrosion problems.

You mean seldom UNDER 106 in the summer?

YEAHHH thanks just rub it in ..just rub it in >:( ;D ;D

Barry, please expand your knowledge.

There does indeed exist a problem that Evans solves. And that is the problem of corrosion. When you keep your cars forever, like I usually do, and when you care what happens to the car after your dead, Evans is a good idea. There is no water in the cooling system, and the result is zero rust or corrosion.

When I was looking into coolants and overheating, I was directed to several users. The consensus was that when one had an ongoing overheating problem, the superior heat carrying/removal ability of the propylene glycol, used together with 'hard' parts designed to take proper advantage of this feature, was a significant problem solver. If you don't have the problem, you don't NEED the solution.

No need here, just currious about this coolant. I really haven't heard much about Evan's being used. If I were to use it, my motor has never had water in it, so rather than spending money using their prep solution to mix with the water and drain it, now would be the time to use the coolant.
-
Looking at the safety data sheet for Evans high performance waterless coolant says it's 80-85% ethylene glycol and uses an organic acid rust inhibitor. They leave you to guess what the remaining 15-20% material is. And since they don't mention it, you can be sure it's not worth mentioning...likely water. The organic acid rust inhibitor will give a few more years of protection but I'd still flush my engine every 5 years or so.
I can see why it causes engines to run warmer. Ethylene glycol has a lower heat capacity than water which means you have to pump it faster to remove the same amount of heat as water.
In my FE powered truck, I use 2.5 gallons of prestone concentrate and 2.5 gallons of distilled water (total cost about $40). 5 gallons of Evans product is about $220 ...same stuff with slightly longer life rust protector.
-
Evans is a glycol mix, varies on the product but ethylene and proplyene mixed with something to make it taste very bitter and a corrosion package, water has to be a very small percentage, probably less than 1%. Water defeats the purpose of using Evans coolant.

Sounds like I won't be using it.
