![]() Additionally, it should also tell you how many kilometres or months before your vehicle’s engine will need a timing chain replacement or timing belt change. If you’re unsure if you have a timing chain or timing belt on your vehicle’s engine, read your owner’s manual. Most of today’s vehicles use timing chains, and most of the vehicles manufactured before 1995 use a timing belt. It’s important to note, not all vehicles use a rubber timing belt. Metal chain links are used in the chain to ride over the toothed sprockets attached to the end of the camshaft and crankshaft in order to rotate at the same time. It connects the camshaft to the crankshaft. When an engine fires over, the timing chain will also be running. A timing chain is an internal engine component which gets lubricated by the engine’s oil in order for everything to work in unison. Timing chains are made with metal rather than timing belts engineered from rubber. Timing belts are an internal component while serpentine belts are located on the outside of the motor, and they can be replaced easily by releasing the pressure on the belt tensioner and installing the new belt. Timing belts are made with rubber however, not to be confused with a serpentine belt which transfers the mechanical power for components like the water pump, alternator or air conditioner. Additionally, timing belts and chains make sure the valves, cylinder heads, and pistons all work in perfect harmony. They synchronize the rotation of the camshaft and crankshaft, which enable the engine’s valves to close and open at precise times during each cylinder’s exhaust and intake strokes. What is a Timing Belt vs Timing Chain?īoth timing belts and timing chains play a vital role in internal combustion engines. Since labour rates are rather expensive when it comes to changing a timing belt, it’s also a good idea to replace your water pump, pulleys, tensioners, and front seals rather than to pay additional labour fees down the road because those components have just as many kilometres as your timing belt does. ![]() If your timing belt or chain breaks, you can expect that other components like the water pump, AC unit, valves, pistons or the engine may need to be replaced in addition to the new timing belt or timing chain. Other Auto Repair Services That May Be Required ![]() On the other hand, it will take the same auto mechanic four to six hours to replace the timing belt, due to the complexity of the engine’s design and tight space however, in both cases, the water pump should also be replaced, which can add additional parts and labour cost to the overall job. For example, if you own a car with a robust room under its hood, and a professional auto mechanic can replace the timing chain in two hours or less. There are many factors that impact the average cost of a timing belt or chain replacement, and in most cases, it comes down to the type of engine in your vehicle, the price of the parts, and the complexity of changing it.
