I know you have all been through this before but I have an unusual case. I have always run ethylene glycol low silicate antifreeze for diesel engines. I wrecked my '96 and the radiator shop ordered the wrong radiator and got in an '01 aluminum radiator. Because of the mistake he gave this to me at no charge (I do alot of heavy equipment business with him). I know automotive engines use a High Silicate antifreeze for protection of aluminum radiators. What should I use in this combo?, what does Dodge recomend in trucks with aluminum radiators? will this work? sorry for the long post
