Evans NPG Waterless Coolant
 

I read an article about this waterless coolant, which sounded like a much better than the tried and true regular ethyl glycol anti freeze.

Has anyone used this, and what are your opinions. I have a clean rebuild I am finishing (455) so this would be the time to introduce it. According to the article, it cools better, has higher boil temp and lower freeze temp and doesn't deteriorate or need replacing nearly as often, and is better at protecting from corrosion.

If all that is true, the only downside I can see would be someone adding conventional coolant at an oil change, or needing to add on the road if a leak develops. I have not had any overheating issues in the past, but regular requires replacing every 2-5 years as regular maintenance.

I've been wondering the same- reviews on Amazon are pretty favorable...

I use filtered or R.O. Water and HyperKuhl :http://www.no-rosion.com/hyperkuhlcoolant.htm. The only downside is there is no antifreeze in it, it is a coolant only. If we have a sustained freeze in the low 20's to high teens I'll drain it.....
Sorry, I have no experience with the product you mentioned.

I've been using this since 2007 in my Firebird. No problems other than the smell. When I shut the car off you can smell hot coolant. Cooling system is in perfect condition. No leaks. It just smells after you shut the car off. I am running a 7 lb. cap. Over the years it has gotten better. I barley notice it now.

There was an article in one of the magazines I read, but I don't remember which. Was either High Performance Pontiac, Hemmings Muscle Machines or Hemmings Classic Car.

I used it several years ago. It works okay but is incompatible with water. So if you find yourself on the side of the road with a small coolant leak, you can't just add water.

And it is 'oily' feeling. I don't know if drag strips would allow it. In theory it sounds great, but until it is widely available, I won't use it again. When I got it, I had to buy it from a guy who met me at a gas station halfway between my house and his, since he was the only dealer for 100 miles around.

When I swapped the cam in that motor, I ended draining the coolant, and had it in old gallon oil containers for about 12 yrs. I ended up just recycling it with used motor oil.

Unless you want to carry some around with you all the time, I think you are better off with coolant you can just add water to in an emergency.

But the oily feeling did make me think that it could be possible to maybe eliminate the two cooling/lubrication systems and have one fluid for both cooling and lubrication.
Imagine a super slippery liquid that could be used in both the crankcase and the cooling system. Seems like that would simplify things. This evans coolant if thicker seems like it would be close.

I think i would try it if it was available locally. I dont want to mail order my antifreeze.. or oil.. or tranny fluid, or beer, etc etc but thats just me

Unrealistically expensive.

Last time I went looking for an MSDS for the Evans Waterless, I couldn't find one. My suspicion is that it's about 50/50 ethelyne glycol and propylene glycol, and you can mix that yourself for about a tenth what Evans is getting.

It was on HPP- I'll post the article if I locate it...

Its been in HPP and Hemmings at least over the last 10 years. Nothing new really. Price and availability have always been the obstacles

Been running it for about 13 years now and have no problems. I use a low pressure cap (about 7 psi) and one time I had an issue with the fan contacting the shroud, the fan cut into the radiator after a blade was bent, and I barely lost any coolant, due to the low pressure. Currently have engine out of the car to put a milder ,more streetable cam in it, and I just drained the radiator and engine block, putting the coolant in 1 gallon containers until I reinstall it (doing some engine compartment detailing and installing 1/4"spacers under my mount brackets due to very high mileage on chassis). Coolant looks good as new, and absolutley no corrosion in system. Being this is now a weekend "fun" car (that I occasionally take on trips over the weekend), I enjoy the extended life the water pump, hoses, and the rest of the system seem to have without changing coolant every couple of years. It was (is) expensive, but it really seems to be a lifetime coolant.:2cents:

I was attracted to the long life part of it. I have owned my Bonneville for 35 years and plan to keep it until I die. If it truly lasts forever and minimizes pump, hose etc. deterioration, then it brings the actual price down quite a bit.

It is not really much of a stretch to think they could improve engine coolant over the past 40, 50, or 60 years, like they have oil. I know the issue with zinc and flat tappet cams, but todays oil, compared to the non detergent oil or even detergent oil from the 60s lubricates and cleans much better. Why not coolant too?

I know that every time I pull the motor, or change cams, or even change radiator hoses, I lose a little coolant. If I was positive that I was never going to get into the motor again, I would consider Evans if it was more easily available, and didn't mind carrying a couple gallons around all the time 'just in case' of trouble on the road.

I don't know if the benefits outweigh the costs, especially considering the incompatability with water when away from home. There is a lot to say for the convenience of being able to just add water when out on the road.

For the strip, I still don't know if tracks would allow it.
