The serpentine belt on your 2002 Chevy Tracker is one complete belt with grooves inside of the belt. The serpentine belt runs all of the accessory pulleys on the front of the engine. The accessory pulleys include the alternator, power steering pump, water pump, air conditioner pump and the crank shaft pulley. Once the serpentine belt has more cracks in the grooves than it does ribs across the belt, it is time to change the belt.

Open the bonnet on your 2002 Chevrolet Tracker and locate the serpentine belt routing diagram on top of the fan shroud. There will be a picture of the serpentine belt routed across the pulleys. This diagram will give you the exact routing direction of the new belt. If you do not see the serpentine belt diagram, take a pen and notepad and draw out the exact direction that the old serpentine belt is routed across the pulleys.
Locate the serpentine belt tensioner on the front of the engine. The serpentine belt tensioner on the 2002 Chevy Tracker is located in the centre of the engine on the front. The serpentine belt tensioner will have a pulley on one end and a spring-loaded arm attached to the pulley. There is also a square hole in the spring-loaded arm section of the serpentine belt tensioner. This is for the 3/8-inch ratchet.
Place the square head of the 3/8-inch ratchet inside of the square hole in the belt tensioner. Turn the belt tensioner counterclockwise to relieve the tension on the belt tensioner. Remove the belt from the belt tensioner pulley. Release the belt tensioner. Finish removing the belt from all of the pulleys and remove the belt from the engine compartment
Slide the new belt over the crankshaft pulley on the bottom of the engine first. Then route the belt across the remaining pulleys. Leave the serpentine belt tensioner pulley for last.
Slide the head of the 3/8-inch ratchet back into the square hole of the belt tensioner and turn it counterclockwise again. Slide the new belt under the belt tensioner and release the belt tensioner. The belt tensioner will then tighten the belt to the proper tension. Remove the ratchet and inspect the belt to make sure that it is evenly under the belt tensioner pulley and that the belt is inside of each pulley.
Crank the 2002 Chevy Tracker and inspect the belt once more to ensure that it is staying seated inside of the pulleys. Turn the engine off.
Tips and warnings
- As stated, once the serpentine belt has more cracks per square inch than it does ribs across it, then it is time to replace the belt. Example: If you have a six-rib belt and you have eight cracks in any 1 square-inch area of the belt, then it will need to be replaced.
