How to Replace the Alternator Belt on a 2000 Mazda Protege
Safety First
Before you begin, ensure your vehicle is parked on a level surface and the parking brake is engaged. Allow the engine to cool down completely to prevent burns. Disconnect the negative terminal of your battery to avoid any electrical accidents.
Materials Required
- New alternator belt (specific to your Mazda Protege year and model)
- 19mm wrench
- 10mm wrench
- Socket wrench with 14mm socket
Locating the Alternator Belt

The alternator belt is typically located on the driver's side of the engine, near the top. It runs around the alternator pulley, crankshaft pulley, and possibly other pulleys (depending on your engine setup).
Removing the Old Belt

Using the 19mm wrench, locate the tensioner pulley. This pulley has a spring-loaded arm that keeps the belt taut. Loosen the tensioner bolt to relieve pressure on the belt.
Sliding the Belt Off
Once the belt is loose, slide it off the pulleys. Be careful not to drop it into the engine bay.
Installing the New Belt

Start by looping the belt around the crankshaft pulley. Then, carefully feed it around the alternator pulley. Finally, hook the belt onto the tensioner pulley.
Tightening the Belt
Use the 10mm wrench to tighten the tensioner bolt. As you tighten, apply pressure to the belt using your hand or a pry bar to ensure a proper fit.
Adjusting the Tension

Using the socket wrench and 14mm socket, adjust the tension of the belt. The belt should be snug but not too tight. Refer to your service manual for the proper specification.
Finishing Up
Double-check the tightness of all the bolts and inspect the belt's alignment. Reconnect the negative terminal of your battery, start the engine, and listen for any unusual sounds or vibrations. If everything looks and sounds good, you're all set!
