Sounds like a wheel bearing.
radiator fans running to cool engine...
There could be a few things that can cause this humming sound. It could be the wheel bearings rubbing, it could be the gears rubbing, it could even be coming from the engine pistons.?æ
an engine is hottest after you turn it off. The humming is the cooling fan automaticly running to cool your engine down for longer engine life.
If this whining or humming is out of the ordinary, it's probably a bearing or bushing on the belt assembly that's wearing out.
Engine surge in a 2004 Kia Sedona is often caused by a clogged fuel filter or dirty injectors. When insufficient fuel reaches the engine, it will exhibit these symptoms.
All Vibes have an electronic cooling fan. The most likely (without any better description than "hum when off") is the fan is running. this is normal until the engine coolant reaches its low end temp.
As long as the engine is running, this is normal.
a temperature sensor that detects when the car reaches a certain temperature before it overheats which kicks on the fan to cool the engine. the fan may not be grounded properly which causes the blowing of fuses to prevent a fire.
There could be a humming noise from the engine of a 2002 Toyota Corolla because of low oil or a fouled spark plug. It can also indicate a more serious problem.
where is the humming noise coming from? if it's coming thru the speakers and matches the rev tone of the engine, then you have a bad ground in your stereo.
There can be a slight humming noise while driving a neon. This sound could come purely from the engine to indicate that it is running.
The humming is a series of explosions in the engine happenning very quickly. Could also be an electric fuel pump if the vehicle is equipped with one.
