When your timing belt has begun to fail then you're going to need to replace it. What Does it Cost to Replace a Timing Belt? When that happens, you will start experiencing problems with your timing belt. These teeth are subject to some serious wear and tear over time and can wear down or break right off completely. There are teeth on the inside of the timing belt which grip on to both the gears at the end of the camshaft and the crankshaft. When someone refers to you as a rubber belt though, that's what they mean. It needs to operate under high stress in high heat, so actual rubber wouldn't get the job done. It will be made of composite material, often something called nitrile or other reinforced fibres. Your timing belt is often referred to as a rubber belt, although it's not actually made of rubber. That can lead to engine misfires, for fuel economy, and if it gets bad enough you could end up causing serious damage to your engine if the crankshaft is rotating but the camshaft is not. When the timing is thrown off, the combustion reaction doesn't care when it's supposed to.

If the timing belt is failing, whether it slips off the crankshaft or camshaft, or the teeth that hook on those parts come loose or break off, then your timing can be thrown off as well. This continually happens over and over again which is what makes your engine work.Īs the pistons move down and rotate the crankshaft, the end of the crankshaft has a timing belt loop around it which connects to the camshaft and causes a proportional movement in that, which makes the valves and cylinders open and close. That takes the form of a small explosion which forces the piston back down again and what is called the power stroke. The movement of the pistons compresses the fuel air mixture, and the spark plug ignites this next which causes combustion to occur. The way your engine creates the power to move your entire vehicle is by a combustion reaction in the engine itself that pushes the pistons which in turn rotates the crankshaft. These are two parts of your engine that have to work in precise alignment in order to ensure the movement of your valves and cylinders with the pistons. The function of a timing belt is to synchronize the movement of your camshaft and your crankshaft.
