Can a bad timing belt cause engine damage?
However, if the issue is due to the timing belt being broken, it may also result in other internal engine compartment damage. In many cases, the timing belt will break while the engine is running.
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.
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.
How often should I replace my timing belt?
You can do a visual check – see if there’s any cracking, glazing, missing teeth or oil contamination. Or you can have a mechanic check the belt for you.

Can a timing belt be replaced with a timing chain?
The timing belt is commonly found in cars and SUVs with smaller displacement engines.

Why does my timing belt make a rattling noise?
The rattling noise can come from any number of things. Check the accessory belt for any bad tension, the exhaust manifold protection, the exhaust hangers, the engine mounts, and finally the engine itself for any problems. Thanks! I have a 2001 Toyota Sienna.
What causes the timing belt on a jeep to break?
However, since this followed a timing belt service, it is very likely that the timing belt was improperly aligned. If this happens then the valves are likely to hit the pistons and crack the rockers in the process. Rockers are specially designed to break off in such a condition of incorrect cam timing. This is a safety measure to limit damage.
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 are the symptoms of a faulty timing belt?
Ticking noise coming from the engine. The timing belt is attached by way of a series of pulleys to the engine’s crank and cam shaft.

What to do if your timing belt is broken?
Engine won’t turn over If the timing belt has broken inside, the engine will not be able to turn over or ignite. When you turn the key, you might hear the starter motor engage, but since the timing belt operates the crank and camshaft, it will not turn over. Obviously, if the car won’t start, a phone call to a mechanic is usually the first step.
What does the pulley on the timing belt do?
The snakelike timing belt on the side of the engine is essential for maintaining your car’s performance. It is controlled by a round pulley called a tensioner that keeps the line taught as it rotates. More often than not, the tensioner goes bad before the timing belt does.
Why is my timing belt tensioner making a noise?
If the noise remains, it may be the timing belt tensioner. Warning: Running the engine with the belt removed will keep the battery from charging and can set a check engine light. Make sure you keep this to a minimum and turn the engine off once you determine whether the noise changes.
Can a bad tensioner cause a belt to break?
More often than not, it is actually the tensioner that goes bad, not always the belt (unless it is really old). Most of the time a belt will break due to a seized pulley or bad tensioner allowing it to contact the timing cover.
What happens when the timing belt snaps on a car?
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. You just pop a new belt on, and the engine should theoretically drive normally.

Why does my car idle when out of time?
An engine slightly out of time can idle roughly since the spark is not in sync with the cylinders. Too much timing advance or retardation causes serious drivability problems. Many problems may upset timing. However, the most common is an overstretched timing belt or chain, or a bad tensioner after miles of operation.
How can I tell if my timing belt is off?
Your mechanic could remove the timing belt cover for a look see, should be able to tell one way or another if it is off a tad. Another possibility depends on whether the engine mount has to be removed to install the t-belt. If so, it may not have been re-installed quite right.
