Timing Belts & Chains :

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.

Your vehicle 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. At Send A Friend we have manufacturer recommended service information, and timing belt replacement is just one of the many repair services our trained, tested and top-of-the line technicians can perform. With the use of our engine diagnostic testing we can tell if you might also need a water pump replacement at the same time, which is very common.
