Have you looked threw your radiator, use a flash light and see how much light
goes threw it at night, it could be plugged up with bugs and dirt, use a water hose and clean the outside fins, I have seen mud in them before, so clean the outside as well........I removed my heavy old 4 blade fan and found a good flex 5 blade fan, I do not have a radiator shroud :banghead: so this helps allot, moves more air sitting in traffic
