The rubber timing belt is part of most internal combustion engines and is responsible for synchronizing the engine’s functions. It controls the rotation of the camshaft and crankshaft and the opening and closing of the engine’s many valves to allow air and gas in and out, which causes the fuel to ignite in the combustion chamber.


Non-interference engines do not risk this contact if the timing belt goes. Nonetheless, a failed timing belt will leave you stranded with either type of engine, so it is important to know the replacement interval for your specific model and have your belt replaced accordingly.


What Is A Timing Belt? A timing belt is a toothed belt made of reinforced rubber that rides on sprocket wheels. Driven by the engine's crankshaft pulley, a timing belt provides rotational force for camshafts that open and close intake and exhaust valves at precisely the right time for smooth combustion.


Average Cost to Replace a Timing Belt. The replacement cost of a timing belt is dependent on the number of labor hours that were spent on the replacement job. After all, with some cars, it is a lot harder to gain access to some of the components like the timing belt.


You should immediately replace the timing belt if it starts having any common symptoms. A timing belt will generally start to produce a high pitched, squeaking, noise before it fails. If the timing belt does break, it will cause a very large sound in the engine as components will be breaking forcefully.


The timing belt is responsible for controlling the camshafts in the engine, and works to regulate the valves at precise intervals. This process depends on a functioning timing belt in order to operate properly. If the timing belt breaks, the best case scenario is the car will stop operating.


Timing belts are a critical part of any engine maintenance program and must be replaced at the specified interval determined by the belt manufacturer or original equipment vehicle manufacturer. Failure to do so may result in catastrophic engine damage. Replacement with a premium quality belt that meets or exceeds original equipment


How much does the timing belt replacement cost? It depends on the engine. Timing belt replacement in a 4-cylinder engine may cost from $250 to $600, plus a little extra if you want to replace the water pump and other hardware. In a V6 or V8 engine, the timing belt replacement cost can run from $380 to $780.


How to Change a Timing Belt. Generally timing belt problems present themselves with no warning. There is no squeak that lets you know it is time. If your car ran fine and then the motor stopped suddenly with a clunk and won't restart, it is likely your timing belt. The timing on the engine must be set exactly, or the...
