What happens when my timing belt fails while driving?
So, if you have an interference engine and the timing belt fails, the camshaft is not turning, and the valves will not open. The piston will still rise into the cylinder and then it will collide with the closed valve. This could damage the cam heads, the valves, the pistons, and essentially destroy your entire engine.
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.
How is the timing belt attached to the engine?
The timing belt is attached by way of a series of pulleys to the engine’s crank and cam shaft. The crankshaft powers the engine’s connecting rods which are attached to pistons inside the combustion chamber.
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.
How can you tell if your timing belt is failing?
As your timing belt wears, these teeth will become deteriorated, meaning that at higher RPM it will have trouble gripping the gears. Watch for strange behaviour at RPM above 2000, as it may indicate your timing belt has lost many teeth and is slipping. The timing belt is what syncs the movement of your pistons to that of your engine valves.
What happens when a timing belt loses teeth?
When a belt starts to lose teeth it will make the timing belt slip. This slipping causes the engine to jolt from the force of the timing belt teeth catching on the gears.
What does the timing belt do in an engine?
The timing belt is an internal engine component that rotates the engine’s cam and crankshaft in sync and ensures each cylinder fires at the appropriate time.
What causes oil to leak from the timing belt?
Another issue that will cause oil to leak is when the gasket between the engine block and timing cover wears out, is cracked or has been improperly installed and is pinched. Leaking oil from the timing belt cover commonly results in engine overheating as well and can prematurely wear the timing belt.
How much does it cost to change timing belt?
The timing belt is critical for all the internal parts to be in sync. If the timing is off, you will surely know it by how the engine runs. Most timing belts need to changed between 80-100K. The cost to do it varies, but always expect several hundred.
What should I do if my Honda Odyssey timing belt broke?
I have taken the top two timing belt covers off and I noticed the front cam ironically is aligned TDC, but the top back cam is 180 degrees away from its TDC. The crankshaft is close to TDC. I don’t have the money to take the car in to pay thousands of dollars to have this done…a luxury I cannot afford right now. Any advice?
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.
What happens when your car’s timing belt breaks?
It depends. Some cars, like Subaru, have non-interference engines, which means that if the timing belt breaks while you are driving, there is no damage to the internal parts of the engine. Other cars do not have this sort of engine and damage results.
How many miles should a timing belt last?
A timing belt should last at least 50K miles, so maybe the belt just came off. Still, damage could occur.
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.

How long does it take to change a timing belt?
As a service provider it is my duty to explain this concept to you the consumer. Many times it is a 4 or 5 hour job to change a timing belt, by not doing the job right and replacing all of the tensioners, idler pulleys and the water pump at the same time puts you, the consumer in harm’s way.
Why did they use timing belts in the 50’s?
Now to all you guys from the 50’s and 60’s typically every engine had a timing chain. The upsides of chains were long life cycle, however the downsides were that they were noisy, had to be lubricated, and the materials used in their manufacture were expensive to produce and install. Enter the timing belt.
How are timing belts connected to the crankshaft?
By definition a timing belt is a toothed belt that connects the camshaft or shafts to the crankshaft thus “timing”the top and bottom of the engine. The camshafts turn at exactly ½ of the speed of the crankshaft to time the valve operation to the piston operation.
