does anyone know how well npg+ works in the p650?. i would appreciate any help, and also is there any modifications needed to be done to the cooling system to use this? thanks for the help.

 

Mickey Dunlap uses it and swears by it.

You need to call evans and ask them what to use. Basically, they have a version that works best in unmodified coolng systems. They will steer you right. They also have a flush that will remove all the old water and antifreeze so it will be good and ready for the good stuff.

 

thanks for the help nyroc. ill prob call them tomorrow before i go to work.

i also want to thank you for all the useful info on your website, its saved me a lot of money.
