How To Maximize The Performance And Lifespan Of Your Timing Belt

Preventative maintenance is the key to maximizing the performance and durability of any water pump. Here’s a list of maintenance tips to share with your customers:

  1. Timing belts typically need to be replaced between 60,000 and 90,000 miles. Check the owner’s manual for manufacturer’s recommendations.
  2. Replacing a timing belt or water pump for preventive reasons typically costs $500 to $900. More than half of the timing belt replacement cost can be attributed to labor cost. By replacing all timing components (belt, water pump, and other pulleys) at one time, money will be saved on labor.
  3. A new timing belt’s life is negatively impacted when it’s used in conjunction with water pumps and other bearings that are worn. Replacing all components of the timing system at once ensures the maximum timing belt life.
