Why does the timing belt tensioner need to be changed?
The timing chain tensioner is a part that requires a lot of work to change. That’s caused by the necessary time to reach the tensioner and to synchronize the chain, which is in the engine, not as a belt that is external.
Where is the timing chain in an engine?
Every internal combustion engine has a timing chain or belt. It’s in the front of the engine attached to a set of gears and pulleys that power components like the crankshaft and camshaft. A properly tensioned chain is critical to maintaining the timing between the pistons and the valves.
Why is my timing chain making a noise?
If the engine is equipped with a hydraulic timing chain tensioner, the noise may disappear or lessen as the engine oil warms up and the tensioner removes some of the slack. If the timing chain wear is great enough so the tensioner can no longer compensate for the slack, the noise may continue even after warming up.
What causes broken guides on the timing chain?
The problem of broken guides on the timing-chain. When the tensioner piston extends, the chain is pulled tight. Removing this slack on one side of the chain also causes the cam sprocket (3) to rotate and change camshaft timing on that bank. Rotating one cam sprocket disturbs valve timing relative to the other side of the engine.
What to do if you have a jumped timing chain?
Place the vehicle in park with the emergency brake set. Start the engine but be sure the battery has a full charge and is operating at peak performance. Note the speed at which the engine tries to start, comparing it with a normal start condition. An engine with a jumped timing chain will show signs of very sluggish and slow starting.
What happens if a timing chain tensioner fails?
Failing of a timing chain tensioner can occur slowly and if you do not catch it in time the slapping chain and lead to a number of engine related problems – some catastrophic. In this video I will show you how to test a tensioner on the bench by comparing one that has failed to a brand new one.
What happens when a timing chain has jumped two teeth?
An engine with a jumped timing chain will show signs of very sluggish and slow starting. This happens because the firing sequence is retarded due to a chain that has jumped a tooth. A chain that has jumped two or more teeth may not start at all. Step 2
Where is the timing chain located in an engine?
The chain is located inside of the engine and needs to be lubricated by the oil in the engine, making oil maintenance important as well. Every time you use the engine, the timing chain is in use. When does a timing chain need to be replaced?
Additionally a mis-adjusted tensioner (too loose) may cause timing chain noise. The moving chain begins to strike or rub against nearby engine parts. If not soon corrected, wear debris could be flushed into the oil pan, picked up at the oil inlet and then partially or completely clog the oil filter.
When do I need to replace my timing chain?
Timing chain systems are designed to endure for the life of the vehicle. Periodic replacement of the chain is not required. However, if noise symptoms or engine operational characteristics (1), (2), (3) or (6) described in “Bad Timing Chain Symptoms” above are noted, evaluation by a qualified service technician is required.
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.
Is a chain tensioner really necessary?
A pulley chain tensioner is necessary when the frame has vertical dropouts because they stop the wheel from moving forward and back. In consequence, one cannot control the tension of the chain without a derailleur or a chain tensioner. But if the frame has horizontal or semi-horizontal dropouts a pulley chain tensioner becomes unnecessary.
What is the timing change tensioner?
The timing chain tensioner is a part that requires a lot of work to change . That’s caused by the necessary time to reach the tensioner and to synchronize the chain, which is in the engine, not as a belt that is external.
How does a cam chain tensioner work?
How it works. The purpose of the tensioner is to take up the slack on the cam chain as it stretches with normal use. It’s designed to only move in one direction. Springs push on a pushrod, which pushes on the cam chain guide.
What is a timing chain kit?
A timing chain kit is a selection of parts that link the movement between the engine crankshaft and camshaft. A basic timing chain kit will include the timing chains (metal links), camshaft and crankshaft sprockets, tensioners, guide rails, and necessary gaskets and seals.
Why do I hear a ticking sound on my timing belt?
If you hear a constant ticking sound, the belt most likely came loose and may need to be replaced as well. Unusual sounds can come from other areas of the car, so make sure you’re hearing them from the engine. Squealing, for instance, could come from the exhaust pipe on the back or the brakes on the bottom of the car.
What are the symptoms of a bad timing chain?
Symptoms of a Bad or Failing Timing Chain. 1 1. Engine misfires or runs poorly. There are two ways to achieve valve timing in a combustion engine. The first is the two-gear method, which includes 2 2. Metal shavings found in the oil. 3 3. Engine won’t start or fails. 4 4. Check Engine Light is on. 5 5. Engine rattles while idling.
What happens when a timing belt goes bad?
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. Listen. A bad tensioner will usually be accompanied by noise.
What are the signs of a timing chain problem?
Whether the timing chain itself has stretched, or a tensioner isn’t doing its job, the result is the same. Here’s some tell-tale signs of a timing chain problem. You might might hear the engine rattle during startup or idling. This is likely the loose timing chain vibrating inside the motor.
Why does my timing chain rattle when I start the car?
Whether the timing chain itself has stretched, or a tensioner isn’t doing its job, the result is the same. First, you might might hear the engine rattle during startup or idling. This is likely the loose timing chain vibrating inside the motor. If the chain is loose, you could have trouble starting the engine or it might misfire while driving.
Is the timing chain the same as the timing belt?
Since the inception of the internal combustion engine, one constant has remained – all of them have a timing chain or timing belt. Most higher-displacement engines have a timing chain as opposed to a timing belt.
What do you need to know about timing chain noise?
In addition to getting your oil changes regularly, you need to use the right kind of oil in your engine too. Check the owner’s manual of your vehicle and see which oil grade and viscosity your manufacturer recommends. You should also choose an oil which has anti-wear additives too.
When to replace the timing chain on your car?
If you ever start having timing chain issues, one of the first symptoms you’ll notice is noise. As the timing chain moves, it will generate a noise which may become intolerable as time goes on. The solution may be to replace the timing chain, depending on what the actual cause of the noise is.
The timing chain tensioner is a part that requires a lot of work to change. That’s caused by the necessary time to reach the tensioner and to synchronize the chain, which is in the engine, not as a belt that is external.

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.
Why is my timing belt out of sync?
This is because the valve timing can become out of sync due to the belt not being tight. Having all of the necessary materials prior to starting the job will make it go more efficiently.
