2001 Toyota Corolla Change Alternator Belt
The 2001 Toyota Corolla came fitted with a 1.8-liter, in-line four-cylinder engine that produced 125 horsepower. The 2001 Corolla came standard with power steering and had air-conditioning as an optional feature. A large, reinforced-rubber belt, known as the serpentine belt, drives the power steering pump, air-conditioning compressor and alternator. Toyota recommends inspecting the serpentine belt every 15,000 miles for visual and structural defects, such as glazing, cracking, fraying or breakage. Replacing this belt at the first sign of defect prevents it from breaking and leaving you stranded.

 Change Alternator Belt
- Loosen, but don't remove, the lug nuts on the passenger front wheel, using a ratchet and socket. Raise the front of the Corolla, using a floor jack, and position jack stands under the subframe. Lower the car onto the jack stands. Remove the lug nuts and pull the wheel from the vehicle.
- Remove the retaining pins securing the inner wheel well splash guard, by prying them out with a flat-head screwdriver. Pull the splash guard from the Corolla, exposing the serpentine belt behind it.
- Draw a diagram of the belt, using paper and a pen or pencil. This aids in reinstallation, in case of a worn-out or missing belt routing diagram on the vehicle.
- Locate the serpentine belt tensioner pulley -- the pulley between the crankshaft pulley and the power steering pump pulley. Place a ratchet and socket on the bolt in the center of the pulley and rotate the ratchet clockwise to relieve the tension on the serpentine belt. Pull the serpentine belt off the pulleys and out of the vehicle. Slowly allow the tensioner pulley to rotate back to its starting position and remove the ratchet and socket.
- Set the new belt on all of the pulleys, except the tensioner pulley, in accordance to the diagram you drew (see Resources).
- Rotate the tensioner pulley clockwise, using a ratchet and socket. Line the serpentine belt up with the tensioner pulley and allow the tensioner pulley to move slowly toward the belt. Remove the ratchet and socket once the tensioner pulley seats on the belt.
- Reinstall the inner wheel well splash guard and press the retaining pins in place to secure it.
- Reinstall the front wheel and hand-tighten the lug nuts. Use a floor jack to raise the Corolla from the jack stands and remove the jack stands. Lower the car to the ground. Tighten the lug nuts in a crisscross pattern to 80 foot-pounds, using a torque wrench and socket.
