Driving The Other Day And Kept Smelling Coolant. When I Got Home I Got Under The Truck And On The Passanger Side I Can See Coolant Leaking From The Head Gasket Down The Side Of The Block!!! I Cant See Much On The Other Side But I Hope The Shop Will Replace Both Sides For Such A Major Job. My Hd Only Has 28000 On It Injector Rates Are Good Always Below 1.oo Except #5 It Always Around 1.75 - 2.20. Has Anyone Seen This Is It A Common Problem???
