Has anybody switched over to the Evans npg+ waterless coolant? My parts manager was debating switching his Cummins over too it and mentioned gas trucks can use it too. And apparently they run no pressure compared to a conventional pressurized system. Any input?

 

I also own a BMW M3, and in the BMW world many have made this switch with success. I myself have not taken the plunge, however I have heard only good things.

 

Apparently it is a poor conductor of heat, some that push the limits experience elevated engine temperatures.


Shameless copy and paste:

SUMMARY OF FINDINGS
Conversion costs of $259 if you do it yourself, or over $400 if you pay a shop to do it.
97%+ removal of all previous coolant is mandatory in order to prevent corrosion.
Inhibitor deposition occurs on aluminum surfaces, which could cause issues in some radiators.
Engines run 115-140oF hotter (at the cylinder heads) with Evans products.
Stabilized coolant temps are increased by 31-48oF, versus straight water with No-Rosion.
Reprogramming ECU fan temp settings is mandatory to prevent the fan from running continuously.
Specific heat capacity of Evans waterless products ranges from 0.64 to 0.68, or about half that of water.
Engine octane requirement is increased by 5-7 numbers.
Computerized ignition must retard engine timing by 8-10o to prevent trace knock.
Engine horsepower is reduced by 4-5%.
Accelerated recession of non-hardened valve seats in older engines is possible, due to brinelling.
Viscosity is 3-4 times higher than what OEM water pumps are rated to accommodate.
Coolant flow rate through radiator tubes is reduced by 20-25% due to the higher viscosity.
Race tracks prohibit Evans products because they are flammable and slippery when spilled.

 

Yeah haha it sounds pretty intense. Might just stick with the motocraft haha or maybe an amsoil.

 

Be very careful swapping out coolants...you may not like what happens next!! All coolants are not created equal. And stay clear of the "Works for all applications" coolants.

 

Just out of curiosity, with all the "side effects", what do you gain??

 

Lighter wallet, lots of hype, never have to change coolant.

 

soooo, forsake the reliability of your vehicle to be lazy?

 

Since you don't need 22lb rad cap to increase the boiling point (it is suppose to run as open cooling system after the conversion) reliability should improve, it's one of their selling points.
For people with Ecobost motors pulling large TT in the mountains and get on here complaining of overheating issues it would not be recommended, for ones with duded up show-off type trucks who only use them on cruse nights to put around A&W parking lots to impress their friends it just might be a cats mew.

 

I will stick with old faithful. Hasn't failed me in 20yrs of driving.
