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