Timing Belt Replacement

Timing Belts & Components

What is it? The timing belt connects the crankshaft to the camshafts, usually the timing belt is also the drive mechanism for the water pump. Other components that require replacement are idler pulleys and tensioners for the timing belt.  The timing belt is located on the front of engine and is covered up for protection.

Why should I change it?

  1. Prevent engine damage. If the timing belt breaks the crankshaft will continue to rotate and raise the pistons up and down, the camshafts will stop rotating and the valves will remain open. The pistons will contact the valves and cause major damage to the valves, pistons, and possibly destroy cylinder walls or the entire engine.
  2. Maintain factory warranty. Failure to perform this maintenance causing engine damage will not be covered under your factory warranty.
  3. Reduce the risk of breakdowns.

Why should I replace the other components in the kit?

  1. All of these components have a shelf life, when the timing belt is due for replacement they are as well.
  2. If any of them fail, the timing will fail also causing engine damage.
  3. If any of these components fail, you will have the expense of going back through the whole job again. It’s usually a long process to remove the timing covers and timing belt.

When should I replace it? Most manufacturer recommendations are at either 60,000 90,000 or 100,000 miles. Time is also relevant, the belt is rubber and usually won’t last more than 7-10 years. If oil or antifreeze are found to be leaking into the timing cover the belt should be replaced as well.
