The drivebelt is located at the right end of the engine and its good condition is critical to the engine's operation. Over time, due to its composition and high stress, the drivebelt stretches and deteriorates, necessitating periodic inspections. A single serpentine drivebelt transmits power from the crankshaft to the alternator, water pump, and air conditioning compressor. With the engine stopped, inspect the full length of the drivebelt(s) for cracks and separation of the belt plies. It may be necessary to turn the engine clockwise using a wrench or socket and breaker bar on the crankshaft pulley bolt to thoroughly inspect the belt. Check for fraying, glazing, and any nicks, cracks, distortion, and corrosion on the pulleys. Small cracks in the edges of the belt ribs are not unusual and unless extensive or very deep, belt replacement is not essential. The drivebelt tension is adjusted automatically by a spring-loaded tensioner. To replace the belt, loosen the lug nuts of the right front wheel, raise the vehicle, support it securely on jackstands, and remove the right front wheel. Open the hood, remove the coolant expansion tank mounting bolts and set the tank aside. Remove the inner fender splash shield for access to the tensioner. Place a wrench on the hexagon portion of the tensioner and rotate it clockwise to release the tension. Slip the belt off the pulleys and slowly release the tensioner. Route the new belt over the pulleys, rotating the tensioner to allow the belt to be installed, then release the bell tensioner. Ensure the bell is properly centered in the pulleys. To replace a faulty tensioner, remove the drive-belt, then unscrew the mounting bolt. On 2017 and later models, the tensioner bolt is covered by a dust cap; use a screwdriver to remove the cap and access the mounting bolt. Installation is the reverse of the removal procedure. Finally, install the drivebelt.
