What is a time belt and how does that work?

An engine timing belt is a fiber reinforced, toothed drive belt made using sturdy compounds such as very saturated nitrile. The time belt permits the crankshaft to journey the camshafts in the cylinder head at half the RPMs the the crankshaft. The camshafts climate open and close the engine intake and exhaust valves in time with the movement and position of the pistons in the engine.

When to change the timing belt?

Every 60k-90k miles. If one engine is equipped v a timing belt, the time belt must be changed at the business interval stated by the vehicle manufacturer nevertheless of whether or not any type of problem is visible, frequently in the selection of 60,000 to 90,000 miles. Your vehicle owner’s hand-operated should state the specific service interval.Engine stop abruptly or will not start. Occasionally, time belts have the right to break, or skip, if the engine is running.Rough engine operation. The molded, reinforced teeth on the time belt engage gears on the crankshaft and also camshafts. After numerous tens of thousands of miles, the teeth deserve to wear or break, or the belt deserve to stretch, hence causing the belt come jump position on the crankshaft or camshaft gears. Must the belt jump, the engine will certainly run poorly and perhaps no at all.Banging or clanking engine noise. On some engines, if the time belt has actually jumped, the pistons and also valves can collide and there will be noise and damage. This engine designs are referred to as interference engines. If your vehicle has an interference engine, instead of the timing belt according to the maintain schedule will minimize the possibility that a belt fail will reason engine damage.

How perform mechanics replace the time belt?

Engine draft vary, and also thus the instead of procedure will vary, yet broadly, the procedure is as follows:

Disconnect the battery soil cable.Once the engine is cold, set the crankshaft to peak dead center with the number one piston top top the compression stroke. Eliminate crankshaft pulley.Remove all equipment interfering with the removal of the time belt covers. Eliminate timing belt covers. Lock camshafts, as required, and also note place of camshaft timing marks. Eliminate timing belt tensioner and also idler pulleys. Eliminate timing belt.If replacing the water pump, carry out so in ~ this time, and of course drain the cooling device first. If the engine cooling mechanism thermostat is only accessible with water pump replacement, the thermostat have to be changed as well.Installation of the new timing belt includes every one of the over steps, perform in reverse, complying with strict guidelines to guarantee camshaft and crankshaft (and balancing shaft, if equipped) space in perfect alignment after ~ tensioner has actually been set.Upon perfect of the installation, the engine crankshaft is turn by hand 720 degrees and the correct position of the timing marks top top the crankshaft and the camshafts is confirmed.The car is road tested come confirm typical operation and also a business sticker is affixed to the engine noting the date of belt replacement and the auto mileage.

An interference engine need to be closely inspected before a damaged timing belt is replaced because it may have actually sustained damage that will have to be repaired prior to installing a new belt.The time belt system contains idler pulleys and also a belt tensioner. These contents should be replaced in addition to the belt. On some cars, the timing belt cd driver the engine’s water pump. Mechanics will typically recommend instead of the water pump in ~ the exact same time the the time belt is replaced.
