Changing a fan belt on a 2003 S10 V6 is a comparatively easy activity that may be accomplished in about half-hour. The fan belt is answerable for driving the water pump, alternator, and energy steering pump. If the fan belt breaks, it could possibly trigger the engine to overheat, the battery to die, or the ability steering to fail.
To interchange the fan belt, you will have a brand new fan belt, a wrench, and a pair of pliers. You must also have a pal or member of the family that will help you with the alternative.
