Within the engine of your Cadillac, a set of valves is used to allow air into the engine, and to expel the exhaust after the fuel has been burned. They are controlled by the Cadillac timing belt, which is connected to the crankshaft and the camshaft. As the engine is running, the camshaft has a set of rollers that tell the individual valves when to open and shut. Adjustments to the Cadillac timing belt can determine the angle at which the camshaft rotates in relation to the crankshaft, and this is expressed in terms of degrees. If the camshaft is ahead of the crankshaft, it is called advanced timing, and if it is behind, it is called retarded timing. These adjustments to the Cadillac timing belt determine how much fuel is burned, how the engine behaves at different speeds, and they can also be used to increase or decrease performance. If the timing belt breaks, it will leave the engine unable to run. Fortunately, this should not happen while driving, if the maintenance schedule for the vehicle is followed correctly. On most vehicles, the Cadillac timing belt should be checked and replaced, if necessary, at anywhere from 60,000 to 100,000 miles.
