Mine did, that is how I new it was going out. A friend of mine that has an ambulance service heard it and warned me that it was going out. The brakes started to get hard also because the booster was not getting enough vacuum.
If the fuel pump is bad it will just quit pumping gas, the electric fuel pump always makes a little noise when running.
No. A bad water pump can make a rumble noise and leak coolant which may lead to the engine overheating.
What you are hearing is the clutch on the air conditioning pump engaging... the alternator doesn't make any noise unless the bearings are going bad and then a grinding noise will be heard.
if the noise is a high pitched squealing noise, the belt is slipping....if the noise is a whine or growling noise, the pump is low on fluid or the pump is bad
have you bled the system...could be trapped air, or even a bad pump
as far as the humming noise and the grinding noise it sounds like your power steering pump is either out of fluid or gone bad completely. as for the muffler? ?MAYBE? the strain from the bad power steering pump is overworking the engine causing it to make noise? answer definetly a bad steering pump as for muffler, the sound can be transfred and magnified on a car, replace steering pump before bothering about the muffler sound may be gone
is the noise coming from the new fuel pump (in the tank)? if so the new fuel pump is bad
unless real bad usaully do not make a noise but give bad vibration.
power steering pump
Abs pump getting bad
It will more than likely leak not make a funny noise. They have a releif for pressure when they go bad.
When their is air in the power steering hoses it will create noise. This is bad, as it can result in a dry pump which will eventually lead to pump failure.
