... overheating issues. most worked engines that I am aware of do when sitting in traffic.

Seriously...?

[myss427]

Most cooling systems are designed for stock motors with a small buffer, when you go bigger cams compression and especially cubes you need to increase size. I know camaro's with big blocks have radiators atleast 6 inches wider than a 308 style radiator, with a much larger engine bay that does not retain the heat.

waste of money , $15.00 gets you a bottle of redline water wetter , as good as it gets and if you decide to take the radiator out or remove the engine just add another bottle .

 
 
Sounds promising, the Redline Water Wetter video is worth watching.
 

I could not find any indication of how often if ever the coolant needs to be changed or move water wetter added.

I would be more comfortable if Redline specified that they meet the requirements of GM 6277M or any of the other vehicle specifications. Most coolant manufacturers list the vehicle specifications that their coolants comply with for example Nulon Specifications Match. You click on the specification and it will list the matching products. Redline only list ASTM D2570 and ASTM D1384.

ASTM D1384
 

This test method will generally distinguish between coolants that are definitely deleterious from the corrosion standpoint and those that are suitable for further evaluation. However, the results of this test method cannot stand alone as evidence of satisfactory corrosion inhibition. The actual service value of an engine coolant formulation can be determined only by more comprehensive bench, dynamometer, and field tests.

 
ASTM 2570
 

This test method, by a closer approach to engine cooling system conditions, provides better evaluation and selective screening of engine coolants than is possible from glassware testing (Test Method D1384). The improvement is achieved by controlled circulation of the coolant, by the use of automotive cooling system components, and by a greater ratio of metal surface area to coolant volume.

Although this test method provides improved discrimination, it cannot conclusively predict satisfactory corrosion inhibition and service life. If greater assurance of satisfactory performance is desired, it should be obtained from full-scale engine tests (Test Method D2758) and from field testing in actual service (Practice D2847).

magic water I can't look at this thread any more.

The Toyota specification coolant is what one of the radiator workshops I deal with recommend and what I currently have in the LS2.

It works out around $55 every four years /80,000 for the LS2.

[ls2lxhatch]

I just picked the Nulon at random as an example of price per 5L. Most long life coolants including the Toyota coolant are around $30-$40 if you buy the 5L premix containers.

That said, in my case price is not the deciding factor. The OP question was "Has anyone heard anything about this stuff, or used it?" not "Is Evans coolant value for money".

 

 

If the Evans coolant lives up to the following claims then I would be interested.

No need to change the coolant again.
No pressure in the cooling system.
No chance of electrolysis.

If I did decide to purchase the Evans coolant then I would look into buying in the USA through LS1 Hatch. The price in the USA is $30-$40 per gallon.

No pressure in the cooling system.

Are you planing on running a cap?

At around 100deg C is there no expansion of this coolant at all?

[ls2lxhatch]

No water means no expansion.

 

You can safely remove the radiator cap when the cooling system is at operating temperature. See around 3:30 in this clip.

What is the attraction of having no pressure though? This is one of the things that increases the boiling point of water (its not 100 degrees under pressure as claimed in the video), and even if there was no pressure the cap and the rest of the system is still hot! (its not working if it isn't)
Also, how does the pump design cope without pressure?

Water is an excellent conductor of heat and that's its primary advantage. This is the main down side of anti-boil, anti-freeze and corrosion inhibitor additives - each makes up for a shortcoming but the compromise is slightly reduced cooling efficiency. Surely the first comparison that should be made is the heat transfer efficiency of this coolant? I don't see that info here...?

Fluid - Boiling Point at atmospheric pressure
 
Pure Water: 100 C / 212 F
50/50 mix of Ethylene Glycol / Water: 106 C / 223 F
70/30 mix of Ethylene Glycol / Water: 113 C / 235 F
Evans Coolant:  190 C / 374 F
 
The pressure in the cooling system is to raise the boiling point of the coolant., 15 psi will raise the boiling point by around 25 C. Source
 
 
 
The attraction of no pressure is that I once had a the heater in my hatch core spring a leak and I got coolant on my feet and legs. I was wearing work boots and jeans at the time. I had just pulled into a car park so was able to get out of the car quickly. A non pressurised cooling system is safer than a pressurised cooling system. It is not a big deal but if you can make it safer and it still works then why not?
 
 
 
According to Evans the temperature in the radiator will be 3 - 7 degrees higher with Evans than it will be with Ethylene Glycol / Water mix coolant. The temperature in the engine will remain the same as it is controlled by the thermostat assuming the cooling system is up to the job. 

Q. Will Evans Waterless Coolant cause my engine to run at a higher temperature?


A. The operating temperature of the engine and coolant may increase slightly, by approximately 3-7 degrees. However the temperature inside the engine will be consistent and steam vapour will not be produced# i#e engines often run cooler with Evans Waterless Coolants.

I've been reading this with interest. 

 

I have no water in my car atm & i'm using an alloy radiator, new hoses/pump ect. 

 

This looks like a good thing to me (mainly because it doesn't carry any electrical charge) , but i'm wondering what it is like on gaskets? 

[76lxhatch]

i have seen ethylene glycol coolant leek out of head gaskets on a new motor start up

Most agree that you should run the engine in or at least do the first startup on straight water
 
 

If you remove the pressure, will the fluid just go where it wants (path of least resistance) instead of going where it needs to be?

I guess this was sorta my question with regard to the pump's effectiveness



Also on the lifetime thing, I'd probably end up dumping the coolant for other reasons every 12 months or so which renders that pointless!

[ls2lxhatch]

The cooling system is a closed system, the static pressure inside a closed system will not make any difference to where the liquid will flow.

 

There is no reason why you can't drain the coolant into a container and use it again when you are ready. I have done that with normal coolant when changing a thermostat or a hose. You could use it in another vehicle if you want.

I don't get the reference to glorified tractor engines. Not that it matters a great deal but I still don't understand it. For me the LS engines are bang for buck the best option available for old holdens. Or an I missing something?

 

 

In my opinion the best bang for buck engine in a big Torana is a SBC with a carby, I consider putting an LS2 in my hatch a mistake.

 

I think that if you have the opportunity to run a engine with a carby then you should take it.
