how to replace rubber pulley belts

you will need to know the make, model, year and engine size when you buy parts. There will be a belt tensioner that is spring loaded that you will have to release the tension on using a ratchet. it will probably have a square drive hole in it or possibly a hex head. There will be a belt routing diagram somewhere under the hood. if you are going to attempt car repairs and are inexperienced it would be wise to buy a Haynes or Chiltons repair manual for your car. good luck.
