Did not even get any kind of advanced warning on this one. Left work drove about 1 mile and all of a sudden I had anti-freeze spraying on the windshield and the truck overheating. Stopped and checked it out could not find any busted hoses or anything, and since I had replaced the water pump 6 months ago, was really hoping that was not the problem. had to let it cool down and then refill the radiator and start it up again to find the problem. The plastic tank on the side of the radiator (Not the overfill tank, but the actual radiator tank) had a 2" long crack down it. Believe it or not I put super glue on it and drove it to the parts store ad bought a new radiator and then drove it to the house where I pulled the radiator out of the truck and opened the box for the new one and discovered that the parts store had given me the wrong one. Had to wait for wife to get home so i could use her vehicle to go back to the parts store, where I learned that there were two different radiators for that year depending on what time of the year the truck was built so if you need one, let them know when your truck was built.
