NPG+ in Duramax ?

[J-M]

Has any one been using the NPG+ in the D/A ? I am thinking of switching over and wondered if any one else has? Any problems or tricks to the conversion? Thanks!

I've been running it for 3+ years. I pulled the drain plugs in the block. Filled the system twice with distilled water to rinse out the death cool.

I have sold Evans to several here to put in the Dmax. I have in my 95 but have not had the chance to put it in the Dmax yet.

Thanks,have you noticed any increase in fuel milage with the NPG+ ? I do not think I will see the claimed increase, but man anything is better than death cool. The electrolis alone is enough to kill the cooling system.I checked mine last week was running 0.8 to 1.0 volts through the coolant. On my 02 I had to ground the rad and heater core to get rid od the free electricty in the coolant. This stuff sounds great. Thanks for the imput.Any other suggestions?
