Makes a loud squealing noise for several seconds and then it will correct itself, it is starting to get for frequent... any ideas?

The bearings are probably worn out.

try having the radiator cap checked for performance. It is not in the engine as any change in rpms would cause a corresponding change in frequency and volume of the noise. However if there is a problem in the cooling system ( leaking head gasket etc) then as the pressure builds up and escapes from under the radiator cap it will give the same affect as a bad tap washer in the household plumbing. Turn it on slightly and the water squeals as it comes out ( tap washer vibrating from pressure fluctuations. I would suggest that a coolant pressure test and a compression test may be in order to eliminate what I have suggested.

it has a dry solder joint internally.

Try to tighten the belts a little firm.Sounds like when engine idling no squelling only when about to take off .Some times belts may seem ok on the outside but if you look on inner side you tend to see cracks in the belts .

Check the motor bearings If your washing machine is making a high-pitched whine or squealing noise while running, the main culprit is usually worn motor bearings. To check the motor bearings, remove the belt and run the motor by itself, listening for the noise. If it makes the noise, than the problem is most likely the result of worn motor bearings and has nothing to do with issues in the rest of the washer. Check for Obstructions Sometimes coins, bra underwires and other metal objects come loose in the wash and become stuck between the tub and the drum. Using a flashlight, take a good look inside the washing machine. If you see dents, scratches or dings, that's a sign that there either are or have been items bouncing around in there that can make a horrible racket. Check for Grease Spatter A high-pitched squealing can be caused when the grease thins around the bearing that's located under the tub. Open up the washing machine and check the interior for grease spatters or spots. That could mean that the grease has thinned out around the bearing and it's making the noise because of rubbing. Check the Drum for Irregularities Spin the drum by hand, listening for the noise. If it makes the noise in the same spot with each rotation, the problem could be with the washing machine drum itself. Parts of the drum can corrode over time, leaving it vulnerable to cracks or rust.

Probably the belt.
Ck out this site for the belt and how to replace inspect it.

sorry for the late reply.

Sounds like the new alternator was run without first fully charging the battery (12.3 - 12.8 volts)
This will destroy an alternator every time -- the classic symptom is a squealing belt.

Noise comes and goes sound like metal on metal not a belt squealing
