timing belt and driving belt replacement interval

I bought an used santa fe 2002. I found the previous owner changed timing belt at 113,000 miles in 2013.(sticker placed inside the hood). Now the mileage is 142000. I do not do sudden acceleration and try to maintain rpm below 3,000 as much as possible. even when i accelerate, i just press it lightly, like senior citizens. I checked the drive belt (the belt seen outside with several pullies and wheels), it seems to be in good condition (no cracking, no faded portions). I am wondering when should I go for timing belt?, I mean at what mileage should my next timing belt be installed? and what ab
Experienced mechanics share their insights in answering this question :
The timing belt should be checked every 24 months or 30K miles and replaced every 48 months or 60k miles. You are not due until 173k for a timing belt replacement, but should get inspected at 143k. The accessory belts should be inspected at every oil change and replaced as needed.

Timing belts are replaced as part of scheduled maintenance, usually every 60,000 to 100,000 miles.
For most Hyundai vehicles replacement should happen at 60,000 mile intervals.
Although Hyundai uses a single timing belt on its 2.7L V6 engines, its 3.3L, double-overhead camshaft engine is equipped with one timing chain for each camshaft and one drive chain for the oil pump.
The petrol V6 has a timing belt and should be changed every 90,000 km. The diesel has a chain that doesn`t require replacement.
Best Answer. A 2.7 engine usually bends two valves when the timing belt goes. The exhaust valves are interfering with the pistons when the camshafts stop turning. One or usually both cylinder heads must be removed, repaired, and reinstalled.
It is safer to replace the timing belt even earlier than the manufacturer recommends. In general, however, timing belts needs to be replaced from 60,000 miles up to 150,000 miles.
Timing belt replacement varies from car to car. It can vary from 50,000 to 70,000 miles. Some cars, it may be a higher mileage. But, 300,000 miles, does not seem possible at all.
Now that technology has improved, timing belts don`t need to be changed as often as in previous decades, but you should still book an appointment to replace the belt between 60,000 and 100,000 miles. In the past, every 60,000 miles was a hard rule.
Although Hyundai uses a single timing belt on its 2.7L V6 engines, its 3.3L, double-overhead camshaft engine is equipped with one timing chain for each camshaft and one drive chain for the oil pump.
If you have a 4-cylinder model from 2003-2007, you engine has a timing chain; if you have the V6 model from those years, it`s a timing belt.
For 2002, the Santa Fe arrived with four-wheel disc brakes and a slightly updated interior. In 2003, Hyundai added the side airbags as standard equipment. A new 3.5-liter V6 engine became available.
Powertrain changes included a choice of the standard six-speed manual transmission or the optional six-speed automatic transmission. Engine choices include a 2.4-litre four-cylinder and a 3.5-litre V6 engine.
The 2.7L V6 engine in your 2004 Hyundai Sonata is an interference engine. There is a good chance one or more valves were damaged when the timing belt broke.
If the belt breaks while you are on the road, the car will break down immediately – and your engine can experience severe damage. You need to look out for signs and symptoms of a weakening timing belt so that you can take action before it is too late.
The 3RZ-FE is an interference engine with a timing chain.
Will a timing belt last 10 years? Most manufacturers recommend replacing the cambelt every 60,000 to 100,000 miles or every 5-7 years, whichever comes first.
However, if the vehicle has a timing belt, there is a very specific interval for replacing it. Timing belt replacement is generally recommended every 60,000 to more than 100,000 miles, depending on the vehicle manufacturer.
It`ll usually need to be replaced more than once over the course of a vehicle`s lifetime. Manufacturers will usually recommend to replace your timing belt after a set number of years or miles. This could be anywhere from 40,000 to 100,000 miles or 4+ years.
Most car manufacturers recommend a replacement interval of between 100,000 and 160,000 km. This means that the belt must be replaced at 100,000 km; then at 200,000 km; then 300,000 km, and so on.
Timing belts are a serviceable item and should be changed as per the manufacturers` service schedule, this is usually between 60,000 and 100,000 miles or 5 – 7 years.
Most vehicle manufacturers recommend replacing the timing belt at 60,000 miles (100,000 kilometers), but others can go as long as 90,000 or 100,000 miles (145,000 to 160,000 kilometers). Check the schedule for preventive maintenance in your owner`s manual.
Should I replace the water pump with the timing belt? It is not necessary to replace both at the same time, however, it is highly recommended due to a high risk of engine damage. All parts of the synchronous drive have the same mileage and wear.
No timing belt will give an increase in performance – it`s just not possible. Its main job is to keep the timing in check. Having your timing belt replaced and noticing an increase in performance is just a mix of the engine operating at peak efficiency and a good hit of placebo effect thrown in for good measure!
There is just one belt. The intake and exhaust cams are connected by a small chain and generally do not need to be replaced.

hi- i got an estimate to replace my timing belt and water pump for my 2012 pilot. Do these figures seem right? Timing belt (35.00)
ANSWER : Hi there. That is a fairly good and detailed estimate for this type of service. It also falls within the price estimation to have a mechanic shop complete this service. However, you might want to consider a third option, of having a professional mobile mechanic come to your location and complete the timing belt replacement and water pump replacement. Simply click the blue links to receive an estimate for both services.

Do I need to replace timing belt again of replacing water pump?
ANSWER : The water pump and timing belt should be replaced as a set if the coolant leaked on the belt. The coolant leaking on it will damage the belt.

Can you change the defected water pump without changing its defected belt (which is the drive belt and only belt in this model of
ANSWER : Hello. Yes you can replace the water pump without replacing the serpentine belt. If the belt is worn, and it breaks while you are driving, you can damage a lot of other components in that area. Typically the price of a serpentine belt is relatively inexpensive. You will have to remove the belt to replace the water pump anyway. Since you are likely going to have to purchase a new pump, we do recommend that you purchase a belt at the same time. You SHOULD replace the belt if it is worn, and this is a perfect time to do it. It is not necessarily required, but you are putting yourself at risk of another break down at a later time. Not to mention if the belt is already worn, manipulating off and back onto the vehicle while changing the water pump can further damage it, and shorten the amount of time its got left. Belts should be replaced before they break, as to the amount of damage they can cause when they do break. Again, you may be able to get away with not replacing the belt right now, but if its as worn as you say, its going to break sooner than later and should be replaced.

Timing Belt Cover replacement and External Belt too.
ANSWER : The parts are touching likely because either the parts were not installed properly or fasteners may be missing or broken. If oil has been leaking, this can cause the seal around the covers to swell as well causing misalignment. Consider hiring an experienced technician like one from YourMechanic who can come out and take a closer inspection of the belt drive to see what is causing the misalignment and offer a more personal diagnosis as well as estimate the proper repairs.

Timing belt is tight and yet appears to be slipping several teeth when belt is rotated,
ANSWER : This is okay since there are more notches on the belt than the amount on the sprockets. Once you aligned the first time the belt marks will almost never line up perfectly again. The marks are used to put the belt on correctly. They aren’t used as an indicator after the engine is turned again. You should be okay to start the motor as long as timing marks on pulleys line up. If you run into any issues, have a certified technician, like one from YourMechanic, assist you with the replacement of the timing belt.

Replaced a timing belt and timing belt tensioner pulley. Still wont run. Why?
ANSWER : If you broke the timing belt while driving then you may have bent the valves. You should have the engine compression checked to see if you are loosing compression due to bent valves. If compression is low then have cylinders leak tested to see which cylinder is leaking and what valves are bent.

My water pump is leaking but I replaced timing belt and pump a year ago. Can I just replace the water pump this time?
ANSWER : Hello. You can just replace the water pump in this case. Although, the cost of just the timing belt is fairly negligible in comparison to the total labor of the job. My estimator says the water pump is a 6.5 hour job. Multiply that by whatever the shop rate is and you have the total labor without parts. You end up saving about $100 or less on parts if you only replace the pump.

The deciding factor will be the condition of the timing belt. If it has problems, you won’t be saving yourself any money by reusing it. In addition, there are seals and pulleys that may need to be replaced as well.

Assuming all the related parts were replaced the first time around, there isn’t a reason you can’t reuse them. I would say you should weigh the savings of reusing them against the actual condition of the parts. This is best determined after a complete disassembly. Keep in mind, time estimates will vary a bit depending on many factors. Either way, the labor is the largest cost.

If you would like to have the water pump replaced, a certified professional from YourMechanic can come to your car’s location to perform this service at your convenience.
