How to inspect and replace a serpentine drivebelt?

The serpentine drivebelt at the engine front drives the alternator and AC compressor and needs regular checks for wear, cracks, and fraying. Minor cracks don't necessitate immediate replacement. To replace the belt, loosen the right front wheel lug nuts, raise the vehicle, and remove the belt from the pulleys. Install the new belt, ensuring it fits all grooves, and release the tensioner. If replacing the tensioner, remove the drivebelt and tensioner bolt(s) first, then replace and reinstall in reverse order.
