How to Replace an Alternator Belt on a 1999 Honda Civic
Your car's alternator belt is a critical component that helps keep your engine running smoothly. If the belt breaks or becomes loose, it can cause serious problems, including a dead battery or even a seized engine. Replacing the alternator belt is a relatively simple task that can be completed in about an hour with the right tools and a little know-how.
Symptoms
There are a few signs that may indicate that your alternator belt needs to be replaced:
- A squealing noise coming from the engine compartment
- Dimming headlights or other electrical problems
- A loose or frayed belt
Materials and Tools
Before you start, you'll need the following materials and tools:
- New alternator belt (refer to your vehicle's manual for the correct size)
- Socket wrench set
- Pliers or belt tensioner tool
Steps
- Safety First: Engage the parking brake and allow the engine to cool completely.
- Locate the Alternator Belt: The alternator belt is usually located near the front of the engine. It connects the alternator to the crankshaft pulley.
- Loosen the Belt Tensioner: Using a socket wrench, loosen the bolt or nut that holds the belt tensioner in place. The tensioner will move, loosening the belt.
- Remove the Old Belt: Slip the old belt off the alternator pulley and any idler pulleys it may be routed around.
- Install the New Belt: Route the new belt around the alternator pulley and idler pulleys, making sure it follows the same path as the old belt.
- Tighten the Belt: Tighten the belt tensioner bolt or nut until the belt is snug but not too tight. You should be able to deflect the belt about 1/2 inch (1.3 cm) with moderate pressure.
- Double-Check: Once the belt is tightened, check the tension again and make sure it is not slipping or too tight.
- Start the Engine: Start the engine and check for any abnormal noises or vibrations. If everything sounds and feels fine, your alternator belt replacement is complete.

Step-by-Step Instructions
Once you have gathered the necessary tools and materials and taken the necessary safety precautions, you can begin replacing the alternator belt on your 1999 Honda Civic.
- Locate the alternator belt. The alternator belt is located on the front of the engine. It runs from the crankshaft pulley to the alternator pulley.
- Loosen the alternator belt tensioner. The alternator belt tensioner is a spring-loaded pulley that helps to keep the alternator belt tight. To loosen the tensioner, use a ratchet and socket wrench to turn the tensioner pulley bolt counterclockwise.
- Remove the old alternator belt. Once the tensioner is loose, you can remove the old alternator belt. To do this, simply pull the belt off of the pulleys.
- Install the new alternator belt. To install the new alternator belt, simply place the belt over the pulleys. Start by placing the belt over the crankshaft pulley. Then, wrap the belt around the alternator pulley. Finally, loop the belt over the tensioner pulley.
- Tighten the alternator belt tensioner. Once the new alternator belt is in place, you need to tighten the tensioner. To do this, use a ratchet and socket wrench to turn the tensioner pulley bolt clockwise. Tighten the bolt until the belt is snug, but not too tight.
Reconnect the negative battery terminal. Once the alternator belt is tight, you can reconnect the negative battery terminal.
Start the engine and check the alternator belt. Start the engine and let it run for a few minutes. Check the alternator belt to make sure that it is tight and not squealing. If the belt is squealing, you may need to adjust the tension.
Conclusion
Replacing the alternator belt on a 1999 Honda Civic is a relatively simple task that can be completed in about an hour. By following the steps outlined in this article, you can save yourself the cost of having the belt replaced by a mechanic.
