Certain Honda models have timing belts that have a limited life span. Your owner's manual will recommend at what mileage the timing belt must be replaced.These intervals range from every 60,000 miles to every 105,000 miles depending on the year and model of your Honda. To see what is recommended for your engine, make sure to check the maintenance section of your owner?s manual.

 

The job of the timing belt is to turn the camshaft(s) at exactly 1/2 the speed of the crankshaft while maintaining a precise alignment. This means that the crankshaft will make two revolutions for every revolution of the camshaft. Engines will have at least one camshaft or as many as four camshafts in some of the V-type engines. The camshaft causes the intake and exhaust valves to open and close in time with the pistons which move up and down in the cylinders.The valves must open and close at exactly the right time in relationship to the piston movement in order for the engine to run properly.

There are two types of engines that use timing belts. They are described as: "Interference Engines" and "Non-interference Engines"The difference lies in the proximity between the valves and the pistons. On an interference engine, if the timing belt slips even one notch, the piston can crash into an open valve causing serious engine damage by bending valves and breaking pistons. Non-interference engines will usually not self-destruct, but in either case if the belt fails, the engine will immediately shut down leaving you stranded.

Timing belts fail without warning. In most cases, your only protection is to change the belt at the recommended intervals.

Depending on what service your vehicle is in for, the Technician may be able to inspect the timing belt to determine its condition We recommend that you replace the water pump during a timing belt job even if there is nothing wrong with it. This is because 90% of the labor to change the water pump has already been done with the timing belt job and it is considered good insurance to replace the pump at this time.

So ask your Service Adviser what his experience is with the water pump on your model car and look at how long you plan to keep the car. This way, at least you will be making an informed decision.
