However, there might still be some related concerns:
* Did it run poorly before the repair? If the car was running rough, making strange noises, or having power issues *before* the repair, you might still have underlying issues. The bad belt and pulley could have been a symptom, not the root cause. Consider:
* Check the charging system: Make sure the alternator is charging the battery correctly. Use a voltmeter to check the battery voltage while the engine is running. It should be around 13.5-14.5 volts.
* Inspect other components driven by the serpentine belt: The belt drives the alternator, power steering pump, air conditioning compressor (if equipped), and possibly other things. If any of these are failing, they could still be causing problems. Listen for unusual noises from these components.
* Check for belt alignment: Ensure the new belt is properly aligned with all the pulleys. A misaligned belt can cause premature wear and squealing.
* Check the tensioner again: Make sure the new tensioner is functioning correctly and providing the proper belt tension. A poorly functioning tensioner can lead to belt slippage or premature wear.
* Were there any other repairs done at the same time? If other work was done, it could be the cause of a new issue or the reason why your car was not running before.
In short, just because the car is running doesn't mean the repair is complete. Do a thorough inspection to ensure all components are working properly. If the problems persist, consult a qualified mechanic for further diagnosis.
