Here's a general guide. Remember, specific details might vary slightly depending on your exact Protege's engine (1.6L or 1.8L). Consult your owner's manual for diagrams and specific instructions.
Tools You'll Need:
* Wrench(es): You'll likely need a wrench to loosen the alternator mounting bolt(s). The size will depend on your car, so check beforehand.
* Socket wrench set: This will give you more flexibility in working with different bolt sizes.
* Ratchet: To make wrenching easier.
* Socket extensions: Might be necessary to reach certain bolts.
* New alternator belt: Make sure you get the correct belt for your Protege's engine. The size is usually printed on the old belt.
* Gloves: To protect your hands.
* Jack and jack stands (or ramps): For safe access to the engine bay. Never work under a car supported only by a jack.
* Wheel chocks: Essential for safety.
Procedure:
1. Safety First: Park on a level surface, engage the parking brake, and use wheel chocks. Let the engine cool completely before working on it.
2. Access the Engine: Raise the front of your Protege using a jack and secure it on jack stands or ramps.
3. Locate the Alternator and Belt: The alternator is usually located on the front of the engine. The alternator belt is the belt that runs around the alternator pulley.
4. Loosen the Alternator: You may need to slightly loosen the alternator mounting bolt(s) to provide slack in the belt. This allows you to easily remove the belt. Do not remove the bolt completely, just loosen it enough to create some give in the alternator's position.
5. Remove the Belt: There are usually tensioners or idler pulleys involved. These pulleys have a mechanism to create slack on the belt. This varies depending on the exact engine. Some require a special tool to loosen the tensioner. Others can be manipulated by hand, or with a long wrench or pry bar. You may need to consult a repair manual specific to your engine for detailed instructions on this step. Once you have slack, carefully slip the belt off the pulleys.
6. Install the New Belt: Follow the reverse procedure for installation. Route the new belt around all the pulleys in the same order as the old one. Make sure the belt sits correctly in the grooves of each pulley.
7. Tighten the Alternator: Once the belt is properly installed, carefully tighten the alternator mounting bolt(s) back to their original tightness.
8. Check Belt Tension: Make sure the belt is properly tensioned. You should be able to push on the belt midway between two pulleys and feel a slight resistance. A repair manual will likely have information on how much deflection is acceptable.
9. Lower the Vehicle: Carefully lower your vehicle using the jack.
10. Start the Engine: Start the engine and check for any squealing or unusual noises. If there are any problems, re-check your work.
Important Considerations:
* Repair Manual: A repair manual specific to your 1998 Mazda Protege is highly recommended. It will provide detailed diagrams, torque specifications, and steps specific to your vehicle's engine.
* Belt Routing: Pay close attention to how the belt is routed around the pulleys. Incorrect routing can lead to premature belt failure.
* Tension: Proper belt tension is crucial for preventing premature wear and squealing.
This is a general guide, and variations may exist depending on the specific engine in your 1998 Mazda Protege. Always prioritize safety and consult a repair manual or qualified mechanic if you are unsure about any step.
