how to change a belt on a 1993 gmc first get the proper belt .then you look at the pullies to make shure they are all good . now there is a pully dampener at the top .you got to lift or push it down to release the tention . now you can remove they belt .mack sure you put it back on they pullys the same way it came off they pullys .if in dought look at the front of your veihcal and there should be a sticker there an follow the sicker on they header panel for they routing
you probably have a pulley with bad bearings. It might not even have anything to do with the timing belt idler pully. There is a serpentine belt right there too. It could be one of the pullys driven by that belt, and the t-belt might be fine. Remove the serp belt and see if the noise stops. If it does, it's one of those pullys.
You should check that all of your pullys are in a straight line. Look at the belt and pullys from the side of the vehicle to see if they are all in a straight line. hope this helps you out.

there is no timing belt it has a timing chain
it depends on what belt it is worse if it is the alternater belt and a pain in the butt if its timing the serpentine belt goes on the front 2 pullys from the top pully you take the belt down and you will se a smooth pully the back side of the belt hits that and goes on the back pully (this is all on the passenger side) alternater belts go behind the serpentine belt and timing belts are in the engine the dots represent the belt its hard to read but it is the best i can do the larger 0 are the main pullys the smaller o is the smooth pully .
The water pump is located behind the timing belt cover. It is driven by the timing belt. If you decide to replace it, replace the belt and idler pullys at the same time.

do you have a diagram on lining up the timing belt where are the pullys marked
This should be a serpentine drive belt. If you havn't removed the belt yet make a sketch of how the belt goes over the pullys. Most vehicles now have a drawing somewhere under the hood. The tentioner for the belt is on top and requires a 5/8" or 15mm wrench to pull the tentioner away from the belt. remove the old, install the new. Pull the tentioner away as far as you need to slip the belt into place. Visually follow the belt all the way around to insure it is in place before starting the motor. HTH Stan If you dont have a belt routing drawing to install the belt go back to your parts store and look in the belt catalog. They have pictures for most all vehicles. Stan
