When it becomes noisy is usually the first sign it needs replacing. It may also be worn so much it will actually jump a tooth which will put the engine out of time and performance will suffer.
The altima uses a timing chain, not a belt.
A timing chain normally will last as long as the engine. Signs of a failing timing chain are chain noise and or engine that continues to jump time.
Signs of a worn timing chain are difficulty starting in cold weather with backfire and sudden brief loss of power while accelerating or decelerating ("stumbling").
Hello, According to the Scheduled Maintenance Interval chart in the Acura RSX Owner's Manual, the timing chain (the RSX utilizes a timing chain instead of a timing belt) should be replaced at the 97,500 mile interval. Although it is recommended to inspect the timing chain every 30,000 mile tune-up/service to look for signs of uneven wear, warping, etc.
Poor performance on takeoff ... rotten gas mileage ... rough idling ... hard starting.
The timing chain on a 2007 Toyota Sienna is designed to last the lifetime of the engine, typically around 100,000 to 150,000 miles. However, it’s important to monitor for signs of wear, such as unusual engine noises, rough idling, or check engine lights related to timing issues. If any of these symptoms occur or you notice a significant decrease in performance, it's advisable to have the timing chain inspected and replaced if necessary. Regular maintenance checks can help ensure the timing chain remains in good condition.
The timing chain on a Vauxhall Vectra 2.2 typically does not require regular replacement like a timing belt, as it is designed to last the lifetime of the engine. However, it is essential to monitor for signs of wear or issues, such as unusual noises or engine performance problems. If you suspect a problem, it's advisable to have it inspected by a qualified mechanic. Regular maintenance, including oil changes, can help ensure the longevity of the timing chain.
Common signs are: Hesitation, poor running, valve clatter, and loss of power. A broken timing belt or timing chain can cause an engine to stop running or cause the valves to crash to the pistons.
Saturn does not recommend changing the timing chain at any mileage. If fact I owned a 96 SL2 that went 240,000 miles and never had the timing chain changed. When I later pulled the engine apart I found the timing chain to still be very tight and it showed no signs of ware. Also read this... "It needs to be changed if it has excessive slack in it. Usually this is indicated by a noise that can be heard at idle and felt in the valve cover. It usually doesn't go away with increased speed. If you replace the chain, I'd also recommend changing the tensioner."
Most likely a rattle from that area in the engine bay when cold that subsides somewhat when engine gets warm.
The timing in a 1992 Ford Aerostar van is managed by a timing chain, which coordinates the movement between the crankshaft and camshaft(s) to ensure proper engine performance and efficiency. Regular maintenance of the timing chain is important, as it can stretch or wear over time, potentially leading to engine misfires or failure. If there are any signs of timing issues, such as unusual noises or performance drops, it's advisable to have the timing system inspected promptly to avoid serious engine damage.
If it i broken, your engine will not start. If it is worn, your engine may run rough.
