What is a timing belt on car?

Answer 1

A timing belt is like a timing chain. It connects the crankshaft with the camshaft. As the crank turns,the belt turns the camshaft thus opening and closing the valves. ther is nothing to wear so the timing stays in sync, but the belts need to be replaced at about 60000 miles. If a belt were to break while you were driving at highway speed, the pistons will still be travelling up and down but the vlaves would not and the possiblilty of the pistons hitting the valves exist. This will cause piston and valve damage.
good luck........

Answer 2

A car engine has many moving parts inside. Think of it as doors opening and closing. When one door opens another has to close or they will collide if they both are open(Timing) When both doors are closed that is when a spark is sent to that cylinder to ignite the gas inside. If the spark happens too late, no power/if the spark happens too soon, it backfires as the ignited fuel goes thru the open door back to the supply. Again no power.
With different style engines gears would mesh. As the engine changed gears could not be used as they got to big, so they use a belt with teeth in it. Just like the gears have teeth, so there was never any chance of slippage, putting things "out of time". As the belt did alot of flexing over the miles it would start to break down. So to supercede the breakage of the belt, it was change at certain distance or time periods and a new one installed.

Answer 3

A timing belt connects the camshaft to the crankshaft. The camshaft opens the intake and exhaust valves. A camshaft runs at exactly half the speed of the crankshaft,that's why the pulleys are different sizes on the camshaft and crankshaft.

Answer 4

It is a cogged/toothed belt that goes from the crank shaft pulley to the cam(s) pulley. It may also drive the water pump on some cars. #25 in this picture of an exploded view of a 2000 Dodge Neon 2.0 liter engine. See link.

Answer 5

It's a rubber and kevlar belt that connects the crankshaft to the camshaft. It keeps the camshaft in time with the crankshaft so the valves open and close at the right time.

Answer 6

Is used to synchronize the rotation of the camshaft and the crankshaft in your cars engine. If the timing is off serious-costly valve/engine damage can result.

Answer 7

If it breaks, you're stranded... and about $400+ bucks poorer. The timing belt is cheap, it's the labor that costs so much.

Answer 8

The timing belt connects the crank shaft and cam shat which opens and closes the intake and exhaust at the correct time .

Answer 9

Here is a site that will explain what you need to know. If it breaks, you are looking at several thousand dollars of expensive repairs. I had mine replaced, and had the mechanic to change the seals and water pump at the same time. This saved me several hundred dollars to have it all done at once.

Answer 10

It is what coordinates the camshaft and the crankshaft timing such that, for every full turn of the crankshaft, the cam shaft turns by one half.
