my car over heated the other day and i ended up replacing the fan clutch water pump thermostat and housing and my radiator. i get it all together and running yester day. i went to the movies and came back no over heating no funny noises. i park in the driveway and get out to tons of steam my fan blades were all missing and some of the pieces of the fan punched some good sized holes in the new radiator. any idea what would cause this? i ran the car with the hood up and everything was clearing the fan fine,
