Hi. It could be the pulley itself or the internal mechanism of the water pump. Begin by lubricating the pulley to see if that quiets it down. IF so change it. Joe

4 thumbs up please. ty.

I'm needing some help. Three months ago my car started making a high-pitch whining noise when accelerating from low speeds then it stops after so many RPM's.

Does it make the same sounds when you start the car? If so, could be a water pump. If you replace the pump, replace the timing chain/belt at the same time.

Also, you might take a lube stick to the belt. One or more could be squealing.

What is causing rattling grinding noise at idle especially in my 89 4.5 DeVille?

The technique I always used to identify where such a noise was coming from was to use a very long screwdriver (2 feet long), while the engine is running. CAREFULLY touch the screwdriver end to each pulley or other object under the hood, and put your ear to the handle. The device making the noise will become very clear.

It could be AC pump/clutch, alternator, water pump, power steering pump, etc.

My 2003 BMW 745Li runs hot in the city but on the hwy no problem makes high pitch noise I think its the Fan coming on and it shifts rough what could be the problem Thermostat maybe

May possibly be water pump also, squeeking comes from belts, if the pump is out the pulley may have locked up. Turn car on, and lift hood. Find serpentine belt and follow to water pump. You should be able to see if pulley is seized, belt will spin, but pulley will not. Also let car run for about 10 minutes, and check pressure in upper, and lower hoses to radiator, that will also let you know if your getting proper pressure.

Water pump

You should be ok running it until the replacement arrives. If the radiator gets hot that indicates that he water pump is still circulating coolant. If you are really worried/curious put a socket on the belt tensioner pulley and remove the belt. Turn the pump pulley by hand. There should be very little resistance. Check for play in the bearing and any roughness or odd noises, although this is not always apparent without the tension of the drive belt on it. Reinstall the drive belt and wait until the dealership can replace the pump seal.

Spinning noise

I always try to help on the first reading of a problem, but we need to know if the car is moving or Parked or in gear. Make, Model, Year of car.

If moving, it could be brakes dragging, transmission problems, bearings. If Parked, power steering pump, water pump, Alternator, A/C compressor pulley or unit. Some apply to moving car too!

Sometimes idler pulleys on the belt, dirty belts wiil make spinning noise, but not grind.

Some time when i start my car the engine will make a humming sound. and some time when i am driving the engine will make the same noise.

Turn off the airconditioning to see if that helps. If it does, then it is likely the airconditioning compressor.

Remove the water pump drive belt. Feel the water pump for free play. If excessive, then replace the pump. You can try spinning it too to see if it's noisy.

WIth the drive belts off, start the car for a few seconds. Twenty seconds tops should do it. Not too long as it will overheat.
Is the noise still present. If not, then check all pump bearings, pulley bearings, tensioner bearings, water pump etc as the noise is one of those things.

sounds like you need to replace the power steering pump,of not overheating or loosing coolant,would check water pump,if no power steering sonds like the pump is bad,mechanic depepnding on their ability could change for you,up to you if you want to pay a shop to replace pump.
