How do you replace the serpentine belt on a 2000 Suzuki Vitara with a 20 engine?
To remove Serpentine Belt Disconnect Negative battery lead. Remove air cleaner box assembly to access alternator. Drain about half litre of Radiator fluid: remove pressure cap with COLD engine and undo drain plug at base of tank. Remove top radiator hose. Unclip power steering fluid bottle (attached to top of radiator on RHS) and tie out of the way with wire or string. Loosen Alternator adjusting bolts to relax fan belt,undo fan housing bolts attaching it to the radiator,undo bolts holding fan to pulley then remove fan housing and fan from engine bay at the same time. replace them the same way(easier this way)be careful not to dammage radiator core. Now you will see both fan and Serpentine belts. Loosen belt tensioner for Serpentine belt (3inch wheel 2 bolts in front)then you can remove both fan and serpentine belts together with fan pulley.You might as well change both as if one is due the other won't be far behind. Assemble in reverse order,don't forget to re-tension both belts and top up the radiator fluid. No special tools required. Not too difficult,take your time. Enjoy.
