Well, it seems noone knew, or were just too afraid to tell me . After deliberation I decided to take it to my mechanic.Turned out to be an 8 hr. job. Had to tear alot of stuff out to just get to it . I even had to take my truck back 3 days later because 1 of the hoses blew off at the firewall . stunk like h#ll. So now my next question is, how about an odor killer for antifreeze...the little trees nor febreeze work... any ideas??
