What happens if the timing belt is broken?
The timing belt is a rubber belt that synchronizes the actions of both the camshaft and the crankshaft to keep your valves safely moving and keep your engine in good condition. If the timing belt that is a key part of the internal combustion engine is broken, this can cause the broken timing belt to destroy the engine.
What happens if the timing belt snaps on an interference engine?
While it is possible that no damage could occur from a snapped belt on an interference engine, such a case is unlikely. In a non-interference engine, the pistons and valves don’t occupy the same space, so if the timing belt snaps, no valve or cylinder damage occurs.
What should I do if my timing belt snaps?
At this point, the camshaft sprockets will align with the marks on engine, and the crank sprocket will align with the marks on the engine. Some engines, like GM interference DOHC V6s, will require special tools keep the cams from moving, so consult with a factory service manual if you can.
Are there any cars that still use timing belts?
Some new car manufacturers, such as Audi, still use timing belts in their engine designs, but for longevity, many manufacturers have switched to metal timing chains that in theory last for the life of the engine. My advice would be to refer to your owner’s manual and look up the maintenance schedule. If you don’t have one, Google it.
What happens when you replace a timing belt?
When replacing any part of the timing belt system, it is important to take care when moving the engine. Some engines are interference engines – meaning that damage to the engine can occur due to piston contact with the valves, should the engine be moved out of time.

What causes a timing belt to break or go bad?
What Causes a Timing Chain to Break? Under-tensioning. If a timing chain is not properly tensioned, it may develop slack, which can result in chain-slap and premature fatigue. Over-tensioning. An overly tight timing chain is placed under excessive stress. Engine Seizure. Situations such as an engine overheating or running out of oil can cause a piston to seize within the cylinder.
Does the timing belt ever break or fail?
In most cases, the timing belt breaks due to normal use , i.e., as a result of the natural wear that occurs during operation.

Can a car run without a timing belt?
Without a functioning timing belt, you do not have a functioning engine whatsoever. Even though it’s a seemingly simple rubber belt, there’s a little more to it than all that and its purpose in your engine can’t be underestimated. The timing belt is what connects your crankshaft to the camshaft in your engine.
Can a broken timing belt cause engine damage?
In a non-interference engine, no matter how low the valves go, the piston will not make contact. Internal engine damage is unlikely. A good mechanic can diagnose if the engine can be repaired, or if a new engine or used engine is needed. Or if the car should be scrapped.
What happens when the cam belt breaks on a car?
They open and close in time with the pistons going up and down to let fuel in and gas out. The cam belt links these valves to the pistons – if it breaks the pistons can hit the valves and do a lot of damage and that means opening up the engine.
How does the timing belt work in an engine?
The timing belt is what connects your crankshaft to the camshaft in your engine. As your crankshaft rotates it allows the pistons to rise and fall in the cylinders of your engine. At the same time, because the timing belt is rotating your camshaft, the valves are also able to open and close.

Which is more important the camshaft or the timing belt?
Let’s state it plainly – nothing is more important than the timing belt. It drives the camshaft, which is what keeps the valves synchronized, and the crankshaft, which controls the pistons. Your timing belt tells the pistons when to rise and fall, and the valves when to open and close.
Why does my timing belt make a squealing sound?
The squealing sound of belts going wrong is not unique to timing belts, but if you hear a squealing sound on an intermittent basis it may be the timing belt struggling. This can happen for any number of reasons including acceleration or even braking.
