What 2006 Chevrolet C4500 owners say
Engine & cooling
Recently, the fan exploded on my 2006 Chevrolet c-4500 and destroyed the cowling around the fan and tore holes in the radiator and hoses into the intercooler. I was pulling a heavy 5th wheel rv. Glad it did not happen when I was changing the fuel filter a few days before. Updated 09/23/10 the consumer stated the fan blade failed. The outer ring came apart and destroyed the cowling around the fan and made holes in the radiator causing anti-freeze to leak out. Updated 09/24/10
Driver heard a loud pop while driving on the highway. Pulled over and saw coolant dripping from the underside of the vehicle. Opening the hood he saw the fan shroud was broken. After being towed we realized that the fan had broken and pieces had hit the shroud shredding it and sending a piece into the radiator.
