![]() When it breaks, the engine will stop running or the components will be out of sync, damaging the engine. The recommended interval for your specific vehicle can be found in your car’s owner’s manual.īecause the timing belt is made of rubber, it will wear down over time and eventually break. Every manufacturer is different, but typically, it needs to be replaced every 60,000–100,000 miles. It’s important to replace your timing belt at the mileage intervals your vehicle manufacturer recommends. As always, check your owner’s manual or give us a call to be sure. If your car has a timing chain instead of a timing belt, you may be able to go longer before replacing the timing chain. Thanks to design improvements and a long lifespan, many modern cars have returned to using timing chains instead. Because they are lighter and quieter, timing belts became popular to use after they were introduced in the 1960s. A timing chain functions the same as a belt, but it is metal instead of rubber. Timing Chainĭepending on your vehicle model, you might have a timing chain instead of a timing belt. If the engine components are very out of sync, they might collide and damage each other, resulting in costly repairs. And if the exhaust valves open too early, the combustion chamber will lose pressure and cause a power loss. If the intake valves open too early, there may be too much fuel-air mixture flowing into the engine combustion chamber, leading to poor combustion and power loss. If the crankshaft and camshafts are not operating in unison, the vehicle will not run correctly. This ensures that the engine intake and exhaust valves open and close in time with the pistons. It synchronizes the movement of the crankshaft and camshafts. The timing belt is a rubber belt with hard teeth that interlock with the cogwheels of the crankshaft and the camshafts. It also sometimes powers the water pump, oil pump and injection pump. Think of a timing belt like a bike chain for your vehicle-it keeps all the internal moving parts of an engine in sync. Read: The Car Maintenance Checklist Every Driver Needs What is a timing belt? Replacing the timing belt is an important maintenance item! So, if you own a car, you should understand how a timing belt works and when to replace it. The timing belt makes sure everything in the engine is operating smoothly, keeping you safe on the road. For jokes, music, cooking, dating-even engines! That’s because your car’s engine relies on a timing belt to stay in sync. To complete installation, reverse removal procedure.Timing is everything. Using new valve cover gasket, install valve cover. 28-.35" (7.0-9.0 mm).Įnsure grooves on valve cover are free of oil, water, and dirt. If timing marks are not aligned, remove belt, realign all timing marks, and repeat installation procedure.Ĭheck timing belt deflection with 22 lbs. Letter "Z" on camshaft pulley and pin on crankshaft pulley boss should face upward. Rotate crankshaft 2 complete turns in direction of normal engine rotation. Loosen timing belt tensioner lock bolt, and allow spring to apply tension on belt. Working in a counterclockwise direction, route belt around pulleys and camshaft sprocket. Ensure crankshaft timing mark is at TDC of compression stroke. Align timing marks on camshaft sprocket and crankshaft. Position notch on crankshaft sprocket to 12 o'clock position (aligned with mark on oil pump). ![]() ![]() Loosen timing belt tensioner lock bolt, and move tensioner away from belt with spring fully expanded. Remove lower and middle timing belt covers. Ensure timing marks on camshaft and crankshaft sprockets are aligned. If timing belt is to be reused, mark timing belt rotation direction. Remove engine mount bracket from timing belt end of engine. Remove valve cover bolts in reverse order of tightening sequence. Remove crankshaft pulley hub bolt and hub. Remove crankshaft pulley bolts and pulley. Align crankshaft pulley timing mark with cylinder No. Remove drive belts and water pump pulley. I would also do replace the water pump as you have every thing outĭisconnect negative battery cable. This is the procedure to removing and replacing the timing belt ![]()
