    I am working on a 308 QV that is a horror show at this time with corrosion due to cooling system electrolysis. I have been seeing more & more of it & noticing more posts with corrosion based cooling problems. It is time for us Ferrari owners to switch to EVANS NPG coolant, I have been running it on 3 of my Ferrari’s for a few years now, no pressure, protects from boil over, eliminates system scaling, reduces corrosion, eliminates pump cavitation, permits more spark without detonation, prolongs hose life, coolant will last the life of the engine, it is rated at 500,000 miles, it is also essentially non-toxic. $32.50 per gallon, worth every penny when you look at the potential long-term damage that can be caused by water & antifreeze to an aluminum engine, also keep in mind that a water-based coolant is operated near its boiling point. Cylinder liner cavitation erosion is caused by vibration-induced high frequency pressure changes at the metal-coolant interface. Coolant, near its boiling point, makes vapor bubbles that abruptly collapse against the metal surface, causing erosion of the metal. EVANS NPG Coolant contains no water and is not operated near its boiling point.

    The boiling point of EVANS (non-aqueous propylene glycol) NPG Coolant is 370 degrees F in a non- or low-pressurized system. The coolant is normally controlled at conventional temperatures but functions perfectly well at higher temperatures, even considerably higher temperatures. Detonation/pre-ignition control and previously forbidden combustion chamber pressures and temperatures are no longer the danger they were to thermal engine efficiency and durability.
    Evans NPG Coolant is 100% inhibited Propylene Glycol. It can maintain substantially vapor free, liquid - to - metal contact at all coolant temperature and engine loads. By bathing the entire combustion chamber with coolant 100% of the time, metal temperatures are controlled to such an extent that critical levels of detonation and pre-ignition are never reached. Because NPG’s naturally high 370 degree F boiling point, the need for adding high pressure to the cooling system is eliminated. Without pressure (or low pressure, i.e. 2 to 5 psi) in the system, gasket seals, hose connections, and even the radiator core, operate safer and longer.

    Is it possible to have it in Europe (Italy, I mean...)?

    Was strongly thinking of switching over to Evans for my old 928 (even corresponded with one of their techs quite a bit). Never got around to it & don't need coolant (aqueous or other) in my 911. Glad you've gotten good results!

    Sounds "cool."

    You run Evans NPG uncut (i.e. without any water 50/50 mixture whatsoever)?

    Any special caveats?

    Sounds interesting but how does it work out in sub zero temps. What is it protection for areas that get down to -10 to -20 F. Also do I assume that you are not changing it yearly and going the full 5 years prior to change. So at $32 a gal. and with these things carrying 19 qts. (say 5 gals.) thats a big chunk of change for coolant. I'll just stick to phosphat free antifreeze and change it every 2 years. Never had a heating issue and car runs at 170* in summer and winter so it works for me. Enjoy the ride

    Is that straight coolant or a 50/50 mix?

    I've had many aluminum engines apart.

    I have seen a few with advanced corrosion.

    Most, even 30+ years old were just fine.

    I suspect that with reasonably regular changes and maintaining a 50/50 mix, a well maintained cooling system will do just fine with the "tried and true" conventional coolant.

    This stuff will cost $130 - $195 to fill your car.

    It is required that ALL coolant be removed from the system first (this will be a significant job with some cars).

    What is the prognosis for cars ALREADY experiencing overheating issues? Does the 'switch' reverse the effects of corrosion?

    I'll try just about anything, but if my experiences with EVANS was any indication, it took them THREE TRIES to provide me with a new radiator that didn't have a pin-hole in it right-out-of-the-box.

    How could anything "reverse the effects of corrosion"?

    What is gone is gone.

    In most cases, a tight cooling system with a good radiator and water pump and a correct (tested) thermostat, properly installed, will not overheat.

    This assumes that head gaskets are okay, the system is full of coolant (no air locks) and the engine is in a reasonably good state of tune.

    Be sure the thermo-fan switch (if applicable) is cycling the fan(s) when necessary.
