Hi all,

Has anyone used the waterless coolants that are available on the x350?

Im about to put my car in for a major service and wondered if anyone had used them?

I wondered given the nature of aluminium if these would be better for our engines?

If you've not heard of them before.. http://www.evanscoolants.co.uk/

Cheers

 

Evans is a great product and will work but why?? What problem are trying to fix?

The normal factory specified coolant works just fine.

The question for me is why wouldn't you? Since I will be doing a coolant change anyhow? These are the advertised benefits:
Eliminates Overheating
Evans Waterless Coolants have a boiling point above 180°C and will not vapourise, thus eliminating overheating, boil-over and after-boil.
Reduces Pressure
Evans Waterless Coolants generate very low vapour pressures reducing strain on engine cooling system components.
Prevents Corrosion
Evans Waterless Coolants contain no oxygen effectively eliminating corrosion.
Increases BHP
Evans Waterless Coolants eliminate pre-ignition and detonation caused by overheating - thus improving combustion efficiency and delivering more power.
Stops Erosion
Evans Waterless Coolants prevent cavitation and eliminate liner and cooling pump erosion.
Freeze Protection
Evans Waterless Coolants freeze below -40ºC

 

This topic has been beaten to death many times. Do a search. This is a classic case of a very expensive product that 'fixes' issues that wouldn't occur in the first place.

It's your car, so ultimately your choice.

 

It also doesn't cool as well as water based coolant. Personally I don't think it's worth it if your car doesn't develop air pockets from overheating to begin with.

 

One of the advantages of a water based coolant is that it does boil (admittedly at above 100C ['cos it's pressurised] maybe as high as 120C) and that boiling is a very good emergency heat remover before things get too hot.

If I recall my school physics it takes one calorie to raise one gram of water by one centigrade degree, but it takes 540 calories to turn that one gram of water into one gram of steam. So, in extremis boiling acts as a very efficient heat remover and prevents the rest of the coolant going above 100C-120C-whatever boiling point ... which gives you time notice it, and to stop.

A coolant that doesn't boil until 180C means the engine can keep getting hotter and hotter, through 100C, 120C, right up to 180C, which in gaosline/diesel auto engine terms is bloody hot ! Think what the associated oil temperatures are going to be. I think you could get you up to 'major engine failure' temperatures very quickly ... ie before you see or smell vapour or realise the temp gauge has gone high, and the first thing you know about it is the sound of your big end and main bearings knocking hell out of themselves (and your wallet).

Nope ... I'll stick to 50% Orange Antifreeze + 50% H2O

 

Thanks everyone for the comments, I did find the other threads in the end, once i'd searched wider than the x350 forum ;-)

After much reading, I've decided against it, although I was interested to see that they (Evans) seem to happily run it on an XKR that they use for promotion!

Cheers

 

It's probably fine in it but it's fixing a problem that doesn't exist i.e. it simply is not needed at all.

 

For cars that only do a few miles a year, it may be worth it, but not for everyday use, as the cost is too high for the benefit gained.

 

Beavis...as has been said, this has been beaten to within an inch of it's life.
These so called miracle products arise by feeding on the average owners conception that it doesn't need replacing.
The simple fact is if service schedules are implemented at the prescribed times with a quality product...what esle do you need?

 

Yes I have and indeed do use waterless coolant, although not in my X350.
I currently use it in my motorbike, which is always kept in A1 mechanical condition, so I don't use it to hide any issues.
My motorbike and in fact all super/hyperbikes are high performance, tight tolerance machines and one of the main reasons I use it, is quite simply if the coolant isn't leaking, I know the level will be bang on (due to the fact that waterless coolant won't/can't/doesn't evaporate), thus I'm safe in the knowledge that my high performance engine is being cooled!
I don't use it in any of my cars currently, because the engines are far more lazy (the redline is half that of my bike) and as stated above, water based coolant is good enough.

 

As an example, the S-Type has a sealed coolant system. No evaporation. Because it's sealed. I haven't had a non-sealed system on any car for many years.

 

Antifreeze coolants are vastly superior to the products of a few years ago. They are formulated to run at least 100K miles in cooling systems made with cast iron, steel and aluminum parts. Even though they utilize water, I have no plans to switch from a long proven formula.

Exactly. A perfect example of attempting to fix something that's not broken.

 

Anybody know what the stuff actually is ? The suppliers are very coy about it. I suspect it costs about 1/10th of the price they sell it for.

 

Isn't this the same thread, from years back, when synthetic oil was first introduced???

Regular oil is 25% synthetic additives so that it provides protection over a wide range of temps. Engine oil is exposed to a very wide range of temperatures, must lubricate and remain stable as well. Antifreeze sees a much reduced temperature range and is a sealed system.

the 50% water mix antifreeze is already 50% synthetic. They probably use the same ingredient for the other 50%. FYI - Most of the synthetic portion of antifreeze is ethylene glycol.
