without hearing it its difficult to say ,but when i change timing belts i always remove the tensioner and idlers and drop them in some diesel for a while then i use a thin sharp instrument to pull teh plastic grease seals and then a squirt of engine oil and a fingertfull of grease ,refit seal and refit ,this gives the bearing another lease of life .alsof course it could be you overtightened the belt or a cover is touching somewhere ,Did you make sure that the serpentine belt is correctly fitted and not one line over the edge of a pulley
i have thought about this,and trying to put this in my mind.and say the tensioner should not move and should most deffently not make any noise it should be silent .is this the right part?the main thing here is the allingment im have a go and saying have you the wrong belt?and you should not have a whinning noise as this susegests a bad bearing i dont think you are far away from the answer?tensioner or belt.adrian ,,,
Only the 2.3 liter diesel is an interference engine. The 2.3 Liter gas is not an interference engine. I would guess the belt was not installed correctly. The belt broke so the cam was then out of alignment with the crankshaft. Unless you aligned it correctly it will not start. BTW, the belt must be replaced every 60,000 miles.
I asume you have the timing cover off, put it back on and set the crankshaft at the 0 mark on the timing cover, remove the cover and don't touch the crank. near the bottom of the cam gear is a protruding piece of plastic with three raised areas, set the cam timing mark at the first pointer, closest to the passenger side . on the back part of the timing cover is a v shaped pointer set the distributor gear mark at the pointer, remove the distributor cap and verify that the rotor is pointing at #1. Loosen both bolts on the tensioner and using a pry bar carefully pry the tensioner away from the distributor gear, tighten the small bolt on the tensioner. install the new belt starting at the crank, then the distributor gear, then the cam, then over the tensioner pulley. loosen the small bolt and the tensioner will adjust automatically. tighten the tensioner bolts and turn the engine over by hand 2 or 3 times and make sure all marks line up ( the cam mark should now be at the center pointer with the crank at 0). I find it handy to paint a reference mark for the crank inside the timing cover.
CLICKon the following LINK. It has the Serpentine Diagrams you will need.
The standard rule to removal the Serpentine Belt: 1. Find the Tensioner(s). (See Diagrams on Link) 2. Rotate/Move the Tensioner away from contact with the belt and towards the area where the belt is not in contact with the Tensioner Pulley. The Tensioner is spring loaded, and is hard to rotate/move. 3. Remove the loosened belt off one of the other more easily accessed Pulleys.

You will find that isn't connected to anything except a bracket. Use a 1/2" breaker bar and pull it away from the belt. To install the new one, just lace it around the pulleys and for the tensioner pulley, pull it out of the way, put the belt in and release the tensioner. You should be ready to go. It should take around 20 minutes.
if it is a screeching noise it will not be your timing belt. It could be your alternator belt or serpentine belt. You can buy some belt dressing (usually good to have) from the parts store and spray some of that on the inside of the belts where it contacts the pulley. You may also have to check the adjustments on both of those belts as well. If you run into this i can help take you step by step, but try this and see how that goes first.
