On vehicles equipped with a timing chain, we can find the tensioner in the cylinder block. When the chain is driven, the tensioner provides the necessary tension and can absorb shock and vibration of the chain, which means that it also improves its resistance to wear.

How do you know if your timing chain tensioner is bad?
You would notice some signs that tell that the chain tensioner is failing, and you can conduct a further inspection to see if there is a need for a replacement. These symptoms often include a knocking sound, check engine light turning on, and an engine misfiring.
What happens when timing chain tensioner fails?
If the tensioner were to fail, there is nothing keeping the chain in place. If the timing chain isn't in place and breaks while the vehicle is running, the valves will be open, and the piston will hit the valves, causing the vehicle to stop running almost immediately.
How much does it cost to replace timing chain tensioner?
The average cost to replace timing chain tensioner is around US$1000 to US$1600. In which the service is around US$600 to US$1000 while aftermarket auto parts are estimated between US$450 and US$600.
What does a bad timing chain tensioner sound like?
Listen for a metallic sound that resembles a rattling or scrapping noise. The sound can be intermittent or constant, but it will be a metal to metal contact. ... If you hear a rattle, metal to metal slapping or scraping coming from inside the cover, it indicates a timing chain noise.
Can you drive with a bad timing chain tensioner?
If the tensioner gets loose enough, the chain may jump timing and could bend the valves and possibly damage the pistons. It can cause a very expensive repair job. Yes of course you can, It actually makes for a very exciting drive!
How do you diagnose a bad tensioner?
If the tensioner is loose the belts may squeak or squeal, especially when the engine is first started. It is also possible for the tensioner pulley or bearing to wear out, in which case the vehicle will produce a grinding noise from the pulley.
What causes chain tensioner failure?
Hydraulically actuated tensioners are known to fail due to low oil levels or oil pressure leaks. The tensioners use oil pressure to keep tension on the chain. When oil levels get low the oil pressure drops and therefore the tensioner doesn't have the pressure it needs to keep the slack out of the line.
How long do timing chain tensioners last?
When does a timing chain need to be replaced? The timing chain normally needs to be replaced between 80,000 and 120,000 miles unless there is a specific problem. Issues with the chain are common in higher mileage vehicles.
What happens if you don't replace timing chain tensioner?
They make the engine work, and if they fail, the chains can leave you stranded anywhere. It could be even worse because if they don't work properly, several components of the engine will start malfunctioning.
How much does it cost to replace a timing chain at a dealership?
Typical costs: Hiring a mechanic to replace a timing chain typically costs $300-$1,000, depending on the make and model of the vehicle, its age and whether the work is performed at a dealership or an independent shop. Purchased separately, a timing chain typically costs $50-$250 or more.
Can I replace a timing chain myself?
Every car has a timing chain. It is the connection between the camshaft and the crankshaft. ... And just like any other car parts, changing a timing chain is required. But you can do the job all by yourself if you have the right tools, some mechanical know-how, and a service manual.
Do you have to remove engine to replace timing chain?
Yes it can if it is an interference engine (the valves and pistons can contact each other if not properly timed). When belts or chains break, the crankshaft keeps moving the pistons up and down for a few seconds but the valves don't move because the drive mechanism (belt or chain) is no longer attached.
Will thicker oil stop timing chain noise?
Heavier oil will not quiet hydraulic lifter noise. Quite likely you will get the opposite effect because thicker oil takes longer to reach the top of the engine. The lifter tapping, or ticking, will be louder. Most vehicles are equipped with hydraulic valve lifters.
Is idler pulley same as tensioner?
The primary distinction between tensioners and idler pulleys is the presence of an adjustable bolt. Tensioners are positioned on the bolt through mounting. Idler pulleys are not mounted to an adjustable bolt. ... However, if bearings fail, tensioner and idler pulleys both require replacement.
Should tensioner be replaced with serpentine belt?
Tensioners add pressure from an adjustable pivot point or spring mechanism to keep your serpentine belt taut as it circulates around the engine. There is no recommended timeframe in which to replace your tensioner, especially as the belt itself usually needs replacing before the tensioner does.
Can a bad tensioner cause loss of power?
If the tensioner's wear leads to the belt fully dislodging, likely through seizing, each of the components that rely on the belt for power will be lost. This means your vehicle's air conditioning, alternator, smog equipment, water pump, and power steering will be lost if the belt dislodges.
