fleet charge anti freeze

[sgt dave]

i went to napa this morning and bought a bottle of fleet charge anti freeze to top off my surge tank. it is a low silicate ethylene glycol formula as required for our trucks, so i open it up and its orange colored. will it mix with the green stuff thats in my radiator now?

general rule of thumb is never mix colors of antifreeze.but lately they have been making mixable types.check the bottle it should say if you can or not.if not take it back and swap it out.
