Q: Weird noise when engine is running.

asked by on

I often hear a "flying saucer" type noise when my engine is running. Some have suggested a belt issue. I had standard maintenance performed at the Nissan dealership, but the problem still remains.

If the belt was replaced already it sounds like it may be coming from the power steering pump. Have a qualified technician inspect your engine noise. If the pump is making noise it needs to be replaced.
