2002 Ford Focus Radiator Cooling Fan Loud

“Hi , We recently changed our radiator out in our 02 Ford Focus (it had a large gash in it, most likely from road dbpris flying up into it). Since changing it, the cooling fan is very loud when it is engaged and running. It is not running hot, so should we be concerned about this issue? If so, what steps should we take to fix it? Thank you.”

OK, first, make sure that the fan blades aren’t touching any part of the radiator or the plastic shroud that holds the fan. THEN, if it isn’t, remove the fan assembly and run it directly from the battery with little jumper wires. It could just be that the fan motor is worn out and wobbling. And this wobbling may have been what caused a gash in the radiator–the wobbling blades could have cut a hole in the radiator.
