- 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 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.

A timing belt is present on a 2000 Toyota Tundra, right?
Timing Belt Or Chain For A 2000 Toyota Tundra? Timing belts are used in the 3.4L and 4.7L engines of the 2000 Toyota Tundra. A non-interference engine is the 3.4L, and an interference engine is the 4.7L.
What happens if the timing belt on a Toyota Tundra breaks?
The engine will run badly and the check engine light will probably come on if the timing belt is beginning to fail. The engine will immediately stall if the belt snaps, and internal engine damage may result.
How long does a timing belt on a Toyota Tundra last?
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.
How much does it cost to repair a timing chain?
Being proactive is a good thing because an engine that has a broken timing chain could suffer significant damage.
Timing chain replacement might cost between $600 and $800 to do it yourself or $1,600 to $1,800 to have a technician do it. Due to how difficult it is to replace this element, the price is exorbitant.
The parts for a DIY timing chain replacement will run you about $650. But this is a job that’s best left to mechanics with a lot of experience.
Fortunately, timing chains are built to endure the lifespan of the vehicle, unlike rubber timing belts, thus it is rare that you will need to have it changed. Watch out for these signs if you think your timing chain may be broken:
- Noisy timing chain
- Starting the car is challenging.
- While idling, the engine shakes or vibrates
- Engine has poor performance or is misfiring
- The check engine light is on.
Bring your car to a repair as soon as you can if any of these symptoms persist. Quickly addressing the problem will stop further harm to your car.

Timing belts for Toyota cars last how long?
Timing belts are important, but unless your Toyota owner’s handbook specifically advises it, they don’t need to be replaced on a regular basis. Between 60,000 and 100,000 miles, some automakers advise changing the timing belt, while others don’t. Many timing belts available now can last 100,000 miles or more before they need to be replaced.
What Toyota engines are causing interference?
Toyota
- 4.7 liters of obstruction.
- 3.4 liters without interruption.
- V6 non-interference, 3.3 litter.
- V6 non-interference 3.0 litter.
- Non-interference 2.0 liter.
- 1.8 liter DOHC gasoline interruption.
- interfering 1.6 liter SOHC engine.
- Non-interference 1.6 liter DOHC (4A-GZE and 4A-GE).
Timing belt or chain: which is superior?
Timing belts typically last less time than timing chains. Timing belts are made of rubber, which isn’t as strong as metal, but chains are made of metal, and this is the simple explanation for why this is the case. Timing belts are not weak, but they will probably need to be replaced at some point, whereas a chain can last the lifetime of the car.
Timing belts typically need to be replaced in the mileage range of 55,000 miles (about 90,000 km) and 90,000 miles (roughly 150,000 km). Therefore, a timing belt is still a very reliable and significant component of your car.
Whether your car has a timing chain or belt, it’s critical that you watch for any symptoms of wear and strain and take appropriate action. Depending on the sort of engine you have, a broken timing belt can have disastrous results. You could be better off searching to get a new vehicle if the repairs are too expensive to be practical.
Is 2uzfe an engine that interferes?
The Toyota 2UZ-FE doesn’t particularly have a problem with timing belts. There are no significant design defects that frequently result in timing belt issues. It merely has to be replaced at the specified intervals due to normal wear and tear. The 4.7L V8 needs to be serviced around every 90,000 miles, however many endure longer than that. But be careful not to push the timing belt’s lifespan too much.
Interference engines are Toyota 2UZ-FE motors. The region across which the piston and valves move overlaps. Valve and piston contact may occur if the timing jumps too far or the belt breaks. That will probably at the very least cause the Toyota 4.7 V8’s valves to be bent. In extreme circumstances, further damage may happen. It’s not really good news, either way.
Once more, this is not anything we would classify as a real issue. Keep track of timing belt replacements. A few sporadic visual checks when the service life is almost through can be quite helpful. It’s a small piece of routine maintenance, but if something goes wrong, it might have major consequences.
UZ-FE 4.7 Timing Belt Symptoms
Several signs of timing belt issues on the Toyota 2UZ-FE include:
- Unusual engine noises
- Misfires
- check-engine indicator
- Poor performance
Prior to the 4.7L V8 timing belt failing, symptoms may not always be present at all. If the belt gets a little slack, you could hear strange engine noises like ticking or slapping. That isn’t always the case, though. This is why infrequent inspections can be quite beneficial.
You’ll probably experience a wide range of symptoms right once if the belt slips or snaps. Misfires, a check engine light, and poor engine performance are signs that the belt has slipped and the timing has jumped. If the belt entirely fails, you will immediately know.
Toyota 4.7 Timing Belt Replacement
The 2UZ-FE engine’s timing belt replacement is a rather easy and inexpensive fix. The majority of timing belt systems include water pumps, which we’ll talk about next. It’s always a good idea to replace the timing belt and water pump at the same time. These Toyota 2UZ FE kits cost between $150 and $400.
It shouldn’t take more than a few hours of labor, but that can raise the cost by an additional $200 to $400. Timing belt repairs for the 4.7L V8 should be quite simple for those who are confident with their do-it-yourself abilities.
When should the timing chain on a Toyota be changed?
Unless there is a specific issue, the timing chain typically needs to be replaced between 80,000 and 120,000 miles. In automobiles with higher mileage, chain problems are frequent.
