Question about 1990 Chevrolet S 10 4WD
Before removing belt, look for a belt routing diagram somewhere under the hood. If you don't see one, sketch a diagram for reference or you may have a struggle getting it back on correctly.
Most gm products with serpentine belt have a springloaded tensioner.
Using either an open-end wrench or a square drive tool (breaker bar, ratchet, etc.), you can relieve tension on the belt, allowing it to slip off of one of the pulleys. This will give you the slack you need. Be careful when remounting the belt that you get the belt properly loaded onto each pulley. If you're off a groove and start the engine, you may seriously damage the belt. While you have it off, inspect for cracks. In my experience, those don't get replaced on schedule. If there is significant cracking on the grooved side, you may want to replace it.
