Anybody running Evans waterless coolant? I'm think of converting my 84 and my S2. Looks to be good option, offers 350+ degree boiling point for no pressure build up in the system and no corrosion potential like water.

Can't say that I see the point...maybe if you're a racer in a hot area?

I can sit in stop-and-go traffic with the AC on max in 100*F weather and not get into the "red zone" running probably 80% water and standard 13psi? rad cap.

I run it in my motion picture wind machines and a 550hp airboat. It helps on lowering temperatures and the best part is freeze protection lasts for years. It tends to turn brown but is not corrosive like water based coolants. If you can afford the initial install I do not know what any other downside could be.

My '83 never goes past the halfway mark with a low temperature thermostat and my (single) oem fan programmed to kick on at 180*.

From my understanding it's a great solution however you must evacuate the system completely of water. Would be a great time if your motor out.

I don't have cooling problems with either car. I was thinking that not having a pressurized system would have many benefits. Longer hose life, no spraying coolant everywhere if a hose does let go, longer water pump seal life, easier on the radiator and heater core too. The non-corrosive aspect of it is appealing too. I read up on the procedure, drain system (radiator and block) with heater on and using high volume low pressure air blow out the system. Fill system with prep, run for a while, drain system again and install the waterless solution, bled as needed. You then check for less than 3% water in the system using test strips.

The whole cooling system is designed to operate at 13-21psi...so I don't think you'll really gain much by taking the pressure off.

Besides, unless you are running 100% water wetter, the water in the system will still boil off at 212* without pressure, right?

And longer hose life...944 rad hoses last 10-20-30 years, what's the problem?

Evans is pure glycol with some aditives. Glycol heat conductivity is very near to that of dry wood. Cooling eficiency of water is superior to any waterless coolant by far.

I used it with the aim of reducing hot spots on the head. Worked great when I was using it. The only real complaints I had were the cost and the fact that it does not evaporate ever. Spill a bit and that puddle will be there forever until you wipe it up. On the garage floor you will get the cartoon banana peel effect.

Beware that some (many?) tracks don't allow it due to how slippery it is.

Agreed. Don't see any need for the OP. Spend money elsewhere.

Thanks guys for the input. Since it's pure glycol I'm assuming it even more toxic to pets than regular antifreeze. That fact plus the "Banana Peel Effect" and my old bones makes me think I'll pass on the stuff.
