Waterless Coolant

mdross1 · #1 (**permalink**) 10-10-2013, 06:24 AM

Been thinking for a while now about flushing out the cooling system of the Cobra and replacing the antifreeze with waterless coolant. Anyone here using this method. Finding that it is not ready available locally.

There are several threads about waterless coolant here on the forum. One of them might be helpful.

I'm using Evans waterless coolant. Its expensive, even getting it off the internet. My cooling system holds 5 1/2 gallons and became even more expensive when a my 2"
to 1 3/4" adapter went south and almost three gallons went down the gutter. Make sure you get every bit of water out of the system before using it. I opened the water jacket fittings, removed the stat and hooked up my shop vac, in reverse, to the water inlet and let it blow for several hours over a few days. Doesn't make the engine run any cooler but now I don't worry about any steam pockets ruining stuff.

Been using it for a long time good in all vehicles. New formulations out in the past year. They even have a product that will help absorb any water left inside.

Only bummer with Evans is, if it gets into the crankcase it takes out bearing instantly vs. h20.

Great to hear about water absorbing product. Plan to do the Cobra in the spring, as well as one of our tractors at least.

Can you please tell me where you found this info because I have never heard of this. I was told by Evans that it was safer then h20 if it got in the oil.

Thanks

I don't understand the logic of using Evans on the street. Cold climates aside (to prevent freezing), unless you decide to haul spare gallons in the trunk, any coolant-based breakdown (split hose, water pump, pin hole in radiator, etc.) is asking for a flat tow. Water Wetter and distilled water really drops the temps without the hassles. And it's one less thing to consider when on the streets. Again, cold climates may demand something different. But that's why many anti-freezes are rated to below 0*F. My $0.02; your mileage may vary.

ACademic, to me, one of the best advantages is that with Evans, there is no pressure build up so there's never any boil over spewing. With no boiling, until 375*, there's minimal expansion (7%, I believe) and a zero or low pressure radiator cap can be used.

You can watch the video with Jay it's self-explanatory. Our older cars are in much better shape over the years with I'll say chemical reactions to different metals involved. If I only had a few cars I wouldn't bother much but it's easier to try to use products across the line with many vehicles. You have no idea what concoctions are needed on certain ones to maintain and are a pain in the a..!

If you have a "coolant based breakdown" you can always fill it back up with water. You loose the properties of the Evans but you can mix it with water in any ratio you want and then just drain it later and refill with Evans. For some reason folks seem to have the idea that you will be stuck and have to be towed back without backup Evans. There really is no down side to Evans. I've been using it in my '38 Chevy for years. One day soon I'll get up enough energy to completely drain the Cobra and use it.

Mastiff107 · #12 (**permalink**) 10-11-2013, 02:40 PM

Oh, as to the problems with Evans getting into the crankcase, not so. I blew a head gasket on the Chevy and drove it for about 6 miles with a crankcase full of Evans and no problem. Don't know where info came from. It has lubricating properties and would be a lot better in the crankcase than water.

The best thing for me is no more worry about long term storage and never have to give the cooling system another thought, Evans is a lifetime coolant. So in the end it is the least expensive way to go by far. Eventually will convert all our rolling stock over to waterless coolant.

Interesting stuff, especially for aluminum engines.
So now the question would be how do you get every drop of existing coolant out of your engine should you decide to use this?
I have seen a few closed vacuum systems that claim to be able to do it.
Just curious...

They also sell a flushing product you run after draining the ethylene glycol. Whatever traces of it that are left are apparently compatible with the waterless coolant.
