It sounds like who-ever put it back together again never tensioned your alternator belt properly and thus when its cold you hear squealing. The hum could be the belt rubbing off of the timing belt cover if that was also put on incorrectly i would think.
It would be beneficial to have it all rechecked before driving it again just to be on the safe side.

High pitched engine squeal upon start up, then goes away I'm thinking bad pulley


All though the solutions above are possible, the squeal usually just means one of your belts is getting going bad.

Pop the hood, and turn your belt slightly (the thinner one, not the timing belt) and see if the bottom side is looking 'glazed' or if there are intermittent cracks. You may need a flashlight to determine this.

If the belt is bad, some times you can just loosen the alternator and get the belt off. Some cars require a lot more work. Don't be surprised if the mechanic tries to get you to replace the water pump at the same time when you take the car in to get the belt replaced.

Depending on your financial situation at the time, it may be a good idea to replace the water pump if you have gone 5 years or more on rhe current one.

Hope this helps, all the best to you,

The belt in my 01 Dodge Dakota squeals badly. Started when I had my power steering pump replaced. I tried changing the belt and the tensioner, but still squeals. Is it possible the pulley on the power...


excess mechanical drag from the pump can cause the belt to slip and squeal, but before focusing on the pump I'd check the condition, tension and alignment of the belt. I might even try cleaning all the pulleys with an aerosol brake cleaner and install a new belt, particularly if the current one has more than 50,000 miles on it. It might be that the squeal is coming from or caused by a different belt-driven accessory.
A more typical noise from a power-steering pump is a high-pitched whine, not a squeal. Usually, if the steering wheel is stationary, meaning that the steering rack is not "asking" for assistance from the high-pressure fluid from the pump, there's little or no noise

I have a high pitched noise which appears to be coming from front right engine compartment (as you are looking at the engine) which sounds kind of like a belt that is squealing. It is intermittent. Just...


Could be several things. WHICH ENGINE?.. 4 cylinder (has three belts, power steering/water pump, alternator & A/C compressor, one tensioner pully A/C compressor), The V6 2.7 (has only one belt, 1 Idler pully and 1 tensioner pully), the V6 3.5 has two belts - A/C/alternator, and power steering - there are two tensioner pullys). Noises can be caused by the belt(s) themselves, pullys, bearings, pully bearings, water pump shaft bearings (or belts/pullys rubbing up against something). Let's not forget that there is also belt(s) behind the Timing Belt cover as well as pullys and bearings associated with the timing system. You could start by removing one accy drive belt at a time (alternator, water pump, compressor, power steering, etc) to see whether or not the noise goes away in each case. If after each case, you discover the noise is still there, it's probably behind the timing belt cover (idler/tensioner pully, water pump shaft bearing, crankshaft bearing, etc.). Good Luck

Squealing from the front of the car some times.


If the squealing changes in pitch with the speed of the motor it is likely the belt squealing. While the belt is removed, check the tensioner and other pulleys for unusual noise when spinning them by hand.
