How to Look for Wear or Cracks on Belts in a Mazda6

1). Prop up the hood of your Mazda6 and look for the drive belts. There can be one or two belts, depending on which year and engine type you have. You may either find one belt around the air conditioning compressor, power steering pump, water pump and alternator or two belts with around the alternator and the other around the power steering oil pump and air conditioning compressor (if equipped with air).
2). Search for any imperfections you can see in any of the belts on your Mazda6. Look for fraying, ripping and cracking; if you see any, replace the belt right away. Deep cracks in the belts causes flexing, which eventually leads to the belt failing.
3). Feel the belt to search for any smooth spots. A belt in good condition will have a slight texture to it. If the belt feels smooth or glossy to you, this is a sign of wear and you should replace the belt immediately.
4). Look for oil on the belts. If you see any, this is most likely a sign of an oil leak. Replace the belt and get the leak fixed.
5). Shut the hood of your Mazda6 and lock it into place. Take note of your findings and proceed accordingly.
