Coolant ?

Mercedes coolant?
I'm close to a bmw and Mercedes dealer today want to pick up some coolant for a flush. Parts department says they have blue and the new one that's clear/pink. Wich should I buy?

I would not buy either. Neither contains nitrites, which your F355 needs because of the wet liners. Zerex G05 is what I use and it does contain nitrites to protect those wet liners. Works great in Ferraris.

I would use what the manual states. Terry, thank you for the post. Very interesting. Guys on Fchat go on and on about BMW coolant being the one to use.

Note to self: Stop visiting Fchat

Evans Waterless Coolant is best.

Water is the ultimate engine enemy and evans runs with zero to 3lb pressure, no hose blowouts. Boiling point is 375 degree's

Used it for 15 years

Does not have the heat absorption capability of water or water and ethylene glycol, so you need to make sure your cooling system is in really good shape for Evans.

Evans coolant is superior to water / glycol in every way and no matter what you use one would be smart to make sure your cooling system is in order. If your cooling system is in bad shape it's because you used water / glycol. Additionally Evans is expensive (it is good for life of car +) and never needs to be topped off so making sure all is good in system will allow you to never ever worry again about cooling issues. No water = no premature failures on cooling components.

There are no negative's to evans coolant.

From Dow Chemical:


System Performance
• Adding antifreeze to water negatively impacts
system performance
– Must trade performance for freeze protection
• Reduced heat transfer efficiency
̶ Antifreeze decreases thermal conductivity & specific heat
̶ How much will system performance be reduced?
• Increased power consumption
– Antifreeze increases viscosity  affects pump
horsepower and fluid flow

OH Yeah Evans is non toxic thus your dog will not die like he / she would when they lick up a puddle of deadly conventional anti freeze

Glad you posted that...Its really hard to know all the ins and outs. I want to make the right choice. I am considering not doing a flush and just a fluid change..I will do the oil also..Is changing the gear oil fairly simple?

FC- Not true. Specific heat absorption of Evans vs water or water and ethylene glycol is much worse. In plain English, Evans cannot pull as much heat from an engine as water or water and antifreeze.


Everybody knows water is more efficient as a cooling medium than water and anti-freeze, but you need the latter for both freezing point depression and corrosion resistance. Both are still much more efficient than Evans at removing heat.


Do not quote marketing material to me. It only tells part of the story, and that is the part they want you to hear.


If Evans was so superior, do you not think high end car manufacturer's would be using it? None are.

I'm no coolant expert but that was my first thought. Thanks, Terry.

Banned, I call BS on these two points as it seems you may have been drinking too much Evans coolant

First pure water is absolutely the best naturally occurring heat transfer fluid on earth, and has a specific heat capacity of 1.007 BTU/lbdegR. All other fluids are fractions of this, including Evans, which has a specific heat capacity of 0.64.

So what does this mean?

For the simplified heat transfer equation of Q = 500 x GPM x deltaT x Cp, it means that for the same water pump flow, say 50 GPM, and the same deltaT, say 20 degrees from top tank to bottom tank, pure water will remove around 503,500 BTU's/hr from your engine, while Evans will remove 320,000. Or put another way, presuming the engine's heat load is the same, then the Evans coolant will result in a higher deltaT, ie the engine will run hotter.

But wait, there's more.

Evans also has a higher specific gravity / density than water

So what effect does that have?

The water pump will pump less volume due to the higher density, so since the engine heat load hasn't changed, the only other variable is deltaT again, and this will cause the engine to run hotter still.

So we have two factors of Evans coolant that will cause the engine to run hotter. This isn't conjecture or my personal opinion, it's first principles of physics and thermodynamics. To compensate for these negatives, you need 1) a bigger radiator and 2) a stronger water pump.

Now, Evans has some very strong positives as well - you pointed out the lack of water as being a plus, and from the corrosion perspective you're right.

You also mentioned Evans' extremely high boiling point of 375degF, which is certainly a plus, and it's for this reason that I plan to try it in my own 550 Maranello.

High mileage, low compression, and missing on a few cylinders.....just like my cars.

As expected the group piles on but Evans Coolant is superior across the board.
There is no positive to placing water / glycol in an engine when Evans is available.

Gee my gauge must be broken

Call BS all you want been running 15 years, for me proof is in that reality of every day driving for you proof is on your note pad.


As I said the Sky is Blue .......waiting, waiting, waiting.

Too Freakin funny.

This is correct. I have not tried it in the 355 (nor do I plan to) but tried it in other cars and ended up with significantly higher coolant/oil temps.

Yes that is the deciding factor on legitimacy, you are right what a fool I am that I did not see this....just can't believe how i missed this key fact.

As hot as 355's run, no chance in hell will I use a product that will result in higher temps.

Thanks guys

All these points are correct, but they're all a result of antifreeze reducing the effectiveness of water. What do you think Evans is? It's 100% antifreeze! To be sure it's propylene glycol instead of ethylene glycol, but it's still antifreeze.

Instead of making a valid argument against water, you've just reinforced all the known and proven disadvantages of Evans.
