The Evans Waterless Coolant is a true lifetime coolant and doesn't corrode the metals in the cooling system and the vehicle runs cooler, just asking if anyone has used it.

If you want to retain your warranty then you'll need to use coolant to Mercedes specs.

Begs the question, if it's waterless what is it? Actually if all ag-bout tu easiest wa-it's about cooling regular DI water works about the best. You could add surfactants to increase it's heat transfer characteristics but only a tiny gain. Hardly worth the effort over water. Add some propolyne glycol for anti freezing and a bit of anti corrosive and your ready to go. I tend to be suspicious of anything that lasts a lifetime. But thats just me. All compounds of this type degrade over time and heat cycling. They may have a somewhat different point-of view

Besides air, and oil coolers, are there any other coolants besides water based used to cool internal combustion engines? I have never heard of any. Also, running cooler is not nessesarily better. If it were, the thermostat, radiator and fans would be designed accordingly.

I am a nubie to MB. So I ask the question. . . How many MB engines die a premature death using the coolant MB specifies?
As a side question, what is used in the F1 cars for coolant? Water based? I know that scale build up etc is not really an issue in the limited life those engines have, but the thermo properties of the coolant would certainly be important.
Just curious questions?

Evans coolant is great stuff.
I used it my other cars and was thinking about using it on the E.
No reason the NPG would not last the life of your engine as there is no contamination from corrosion.
However, I prefer the NPG+, which cools better but does not last as long.
It's expensive, due to the need to flush all old coolant and water.
Usually I flush twice with Evans flush fluid and then do an NPG+ fill and then dump and refill with NPG+ again.
Temps run a little hotter than water but there is no risk of boiling and internal pressure is low. If I had to drive across a long dessert I'd want Evans in my cooling system.

And when Mobil 1 came out it was the anti-christ to conventional motor oil until they realized it was better, which I have been using it for 25 years in all my vehicles.

Most, if not all race engines will use plain old deionized water. Has superior heat transfer qualities. Also most tracks will not allow the use of glycol additives to water as a leak will be like pouring oil on the surface of the track. Also making clean up a mess, water just evaporates. This is just one of those odd cases where simple and cheap is best.

I first learned of the existence of this coolant a few days ago...can't recall where.I then did some research and learned (unless I misunderstood) that one or more modifications to the cooling system were required to use it.If that's correct it's a deal breaker to me....particularly when the warranty is still in force.

There are only two issues with using distilled water. 1) Water freezes at 32 degrees. If your vehicle will be in a location that will have seasons at or below freezing, damage to the block will occur. 2) water lacks the lubricating properties that are good for the seals in the water pump. When I was growing up in south florida, I regularly flushed the rust out of my cars and refilled with distilled water. Never a cooling problem. Went through a few $15 water pumps though.

Just a viewpoint. As already stated, not for or against, just curious about the real benefit.

Evans works great for the right application. For our E350-550 it is not really worth the expense to change coolant being that they are NA. Now if the cars had turbos and or superchargers plus highly modified that would be a different story.

Evans is very good coolant. However, it is overkill for street driven cars, except for Turbo Engines as captj3 pointed out.
Although, I'd run it in a heartbeat, if my car was out of warranty, as I feel it would result in less chance of cooling related engine repairs, that would be at my expense.
Another good thing is that it helps you find leaks easily due to its coke like odor and not boiling away. Gives you a chance to spot problems early.
