Although they can last up to 100,000 miles, it’s always a good idea to change them before that. The valves, pistons, and other internal engine components can sustain significant damage in the event of a belt failure.

When should the timing belt be changed?
- 60 to 90 thousand miles. Whether or not a problem is apparent, a timing belt that is installed in an engine must be replaced at the service interval dictated by the vehicle’s manufacturer, which is normally between 60,000 and 90,000 miles. The precise service interval should be stated in your vehicle’s owner’s manual.
- Engine unexpectedly shuts down or won’t start. Timing belts may occasionally skip or break while the engine is operating.
- erratic engine performance. The timing belt’s contoured, strengthened teeth engage the crankshaft and camshaft gears. The belt may stretch or the teeth may wear out after many tens of thousands of kilometers, which will cause the belt to shift positions on the crankshaft or camshaft gears. The engine will likely operate poorly or not at all if the belt jumps.
- engine noise that is clanging or banging. The pistons and valves may clash in some engines if the timing belt has jumped, causing noise and damage. Interference engines are the name given to these engine types. The likelihood that a timing belt failure will result in engine damage will be reduced if your automobile has an interference engine by replacing the belt in accordance with the maintenance plan.
Nissan Sentra Chain Or Belt
All Nissan Sentra cars from 1989 through 2021 use interference engines and timing chains. Timing belt and an interference engine are standard on Sentras built between 1982 and 1988.
In contrast to the 1988 Nissan Sentra 1.6L 4 Cyl. 70 hp (E16i) option, the 2021 Nissan Sentra 2.0L 4 Cyl. 149 hp (MR20DE) option includes a timing chain.
How urgently do you need a new timing belt?
Timing belts should be replaced beforehand according to the manufacturer’s recommendations as part of regularly scheduled maintenance. Timing chains are made to endure the lifetime of your car and won’t need to be replaced unless they break. Timing belts and chains should be replaced right away if they stop functioning properly to prevent harm to your engine.

My 1993 Sentra no longer exists, but it had a timing CHAIN that never needs to be replaced. Perhaps your 1992 Sentra is comparable.
Why use a timing chain over a timing belt?
Your engine’s camshafts are managed by your timing belt or timing chain. For this reason, it’s sometimes referred to as a cambelt. Rubber timing belts with interlocking teeth are used to match the timing of the crankshaft and camshaft. It’s a crucial component that you shouldn’t break.
While a timing chain serves the same purpose as a belt, it is more robust and needs oil to operate smoothly. A belt’s advantages include efficiency and quiet operation, but they also have a lifespan of 60,000 to 90,000 miles. A timing chain should last the entire life of your car. Nissan employs a timing chain in the 2017 Nissan Sentra for this final justification.
Why would you want a system that is belt-driven? Timing chains are typically used in applications where durability is a top concern, but timing belts offer greater cam timing control. It’s more important for drivers who want to tune their engines to take this into account when driving performance vehicles. A hobbyist activity that can ruin the guarantee on your new car.
How much does a Nissan timing belt cost?
Belts don’t cost a much by themselves. Since many pieces must be removed in order to reach the belt, labor is where the true expense lies. Your best chance is to shop about and compare prices, but be prepared to pay anything between $409 and $919. (including parts and labor)
What is the recommended mileage for timing belt replacement?
Depending on the vehicle manufacturer, a timing belt replacement is often advised every 60,000 to more than 100,000 miles. To get the suggested service interval for your car, consult the owner’s manual or the maintenance schedules on ChiltonDIY.com.
After five years, should I update the timing belt?
When to change your cam belt is not a fixed rule. Your car’s make, model, and how frequently you drive it are all factors. Over the course of a vehicle’s lifetime, it will typically need to be replaced more than once.
Timing belt replacement is typically advised by manufacturers after a certain number of years or miles. This might take between 40,000 and 100,000 kilometers or more than four years.
Can I replace my own timing belt?
It does need some engine knowledge to replace a timing belt and water pump, so if you don’t have much expertise working under the hood, we advise leaving it to the experts. However, if you prefer making your own repairs and restorations, you can do it yourself and avoid paying hefty repair expenses in the process.
Starting with the tools you’ll need, we’ll walk you through the replacement of a timing belt and water pump step by step.
If I don’t replace my timing belt, what happens?
At the recommended mileage intervals for your vehicle, it’s critical to change your timing belt. Although every manufacturer is unique, it should normally be changed every 60,000–100,000 miles. The owner’s manual for your car will list the suggested interval for your particular vehicle.
Since the timing belt is constructed of rubber, it will ultimately wear out and break. The engine will cease working or the parts will be out of sync, which will harm the engine, when it fails.
If you don’t change the timing belt when it needs to be, you risk having an entirely failed engine, broken or bent valves, damaged cylinder heads or camshafts, damaged pistons, and damaged cylinder walls. It is not safe to apply the maxim “If it ain’t broke, don’t fix it” in this instance. To prevent spending thousands of dollars on engine repair or replacement, replace the timing belt in accordance with the manufacturer’s recommended maintenance schedule.
How much does a timing belt replacement cost?
Since many pieces must be removed in order to reach the belt, labor is where the true expense lies. Your best chance is to shop about and compare prices, but be prepared to pay anything from $367 to $585.
What are the indications that a new timing belt is required?
- Under the hood, there is a ticking sound when the engine is operating.
- The engine won’t turn on.
- While driving, the engine was misfiring.
- Under the hood, on the front side where the motor is, there is oil dripping.
- driving when hydroplaning in a slick environment.
- The check engine light is on.
How can my timing belt be checked?
To check the belt, start by examining its exterior to determine if any teeny cracks are developing. The timing belt is an extremely durable rubber-covered metal-reinforced belt. The rubber should be generally smooth, without any large cracks or missing sections.
Is the serpentine belt the same as the timing belt?
Horizontal “teeth” on a timing belt are designed to accommodate the crankshaft and camshaft. A serpentine belt, on the other hand, has numerous vertical V-shaped grooves running the length of the belt. These belts must be changed eventually (roughly around the same time)
What causes a timing belt in an automobile to fail?
An engine may make a ticking or clicking noise when the timing belt is worn out. Low oil pressure may be the cause of this noise, which may harm the timing belt. The engine oil applies pressure to the tensioner to keep the belt taut. The belt will become loose, maybe disengage from the pulleys, and/or break if the tensioner has no oil pressure. The timing belt will break if the camshafts are unable to operate effectively due to a lack of oil pressure.
What malfunctions a timing belt and why?
We’ve compiled a list of issues and potential causes with ProTorque to assist you in determining the cause of timing belt failure. To prevent your drives from grinding to a halt and preventing unplanned downtime, visually inspect your timing belt drives for these top 6 failure-causing issues.
1. Asymmetry
One of the main reasons why timing belt drives fail is misalignment. Misalignment can be the cause of excessive or uneven tooth wear, belt tracking, and tensile failure. You can extend the life of your timing belts and reduce downtime by inspecting and straightening your shafts and timing pulleys.
2. A heavy load
Excessive load is almost certainly the root of the problem if the timing belt teeth are shearing. Excessive load or shock loads can also lead to tensile failure, and even excessive tooth wear, though the latter is less frequent. You’ll need to redesign the drive to fix this issue.
3. A Belt That Is Not Tightened
Ratcheting, or tooth skipping, is likely caused by your belt being under-tensioned. Use a tension gauge to adjust the proper tension on those timing belts since under-tensioning can also lead to excessive or uneven tooth wear and excessive driving noise.
4. Poor drive architecture
You may have a poor drive structure if your drive vibrates excessively or your timing belts appear to be stretched. You could try strengthening the drive structure to solve the issue.
5. Worn or damaged pulleys
Timing pulley wear or damage will significantly shorten belt life. Belt wear and/or damage are both results of worn teeth. The belt might be cut by nicks or gouges. Inspect pulleys for wear and replace them if necessary.
Debris is the most commonly disregarded source of issues for your timing belt and pulley. The materials of the belt might be harmed by oil and abraded by dirt on the teeth. Dust and rust can be removed by using a hard brush. Eliminate grease and oil by wiping. Any of the aforementioned causes of timing belt failure can be attributed to debris, so go clean those pulleys and install a shield on that drive!
Any other cause of failure should be regarded as abnormal. A timing belt will eventually fail due to tooth loss in what is considered normal use. Check your belts and timing pulleys by consulting our Timing Belt Troubleshooting Guide for a complete list of potential faults and the appropriate course of action.
Will my engine be destroyed if my timing belt breaks?
First of all, how could you possibly predict when your timing belt will fail? Your car cannot function at all without a timing belt, which is really fairly basic. The automobile will quickly break down if the belt breaks while you’re driving, and your engine could sustain extremely catastrophic damage. In order to take action before it is too late, you need to be on the lookout for warning signs and symptoms of a weakening timing belt. These include your engine making loud clicking or screaming noises, misfiring, and not starting at all.
Is it worthwhile to mend a damaged timing belt?
Explain what occurs when a timing belt breaks to help a consumer appreciate the value of a preventative timing belt repair. Basically:
The camshaft halts turning when a timing belt ruptures. Some of the engine valves are now stuck open as a result. The pistons, however, will continue to move. They will strike the trapped open valves in an interference engine. This may harm the piston and cylinder head, as well as bend or shatter valves. In essence, a damaged timing belt causes significant engine damage. In certain cases, replacing the entire engine is less expensive than repairing it.
Timing belt replacement is substantially less expensive in the long run than timing belt damage repair.
