When you have the timing belt replaced at a reputable service center, the service should also include a few other things. The tensioner and idler rollers should also be replaced. The technician will also inspect the crankshaft seal and the camshaft seal, replacing them if necessary.
Timing belts must be replaced on a regular basis, but timing chains do not. There`s no reason to alter the timing chain unless it`s damaged, strained, or otherwise affected.
Every 60k-90k miles.

If an engine is equipped with a timing belt, the timing belt must be replaced at the service interval specified by the vehicle manufacturer regardless of whether or not any problem is visible, typically in the range of 60,000 to 90,000 miles.

The average cost for a Lexus GX460 Serpentine Belt Replacement is between $119 and $130. Labor costs are estimated between $44 and $56 while parts are priced between $75 and $75.
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.
When the timing belt is replaced, other parts, including the tensioner, should be replaced at the same time. This is because these components wear out at essentially the same rate as the belt. For instance, the tensioner bearings could dry out or even seize.
Timing chain when to replace? As mentioned before, replacing the timing chain kit is one of the most important maintenance steps your car will need. Normally it needs to be replaced between 80,000 and 120,000 miles.

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.
The recommended replacement according to mileage ranges from 60,000 miles to 150,000 miles. If your vehicle is 6 to 10 years old, it is recommended to replace the timing belt.
A timing belt replacement is a fairly labour-intensive job; usually taking between 3 and 8 hours depending on the vehicle. While the repair usually isn`t particularly challenging for a properly-trained and experienced technician, there are certainly several steps where a minor mistake could lead to major engine damage!
So when the water pump must be replaced, it is a good idea to go ahead and also replace the timing belt, timing belt tensioner and idler pulleys.
If the pulley is damaged, replace the tensioner assembly not just the pulley. If an idler pulley is damaged, inspect the tensioner also because vibrations caused by a bad idler pulley may damage the tensioner.
Often times, it just breaks. That`s why most manufacturers recommend you have your vehicle`s timing belt replaced every 60,000 to 100,000 miles. Refer to your owner`s manual to see what is recommended for your specific model.
When it breaks, the engine will stop running or the components will be out of sync, damaging the engine. If you don`t replace the timing belt at the recommended time, you could end up with total engine failure, broken or bent valves, cylinder head or camshaft damage, and piston and cylinder wall damage.

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.

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.

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.

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.

on timing belt replacement, what else should be replaced?
ANSWER : Hello. When changing the timing belt there are other parts that should also be replaced while you are in there. I would replace the timing belt, the idler pulley, the tensioner and pulley, the water pump, and the camshaft and crankshaft seals. It is also important to change the serpentine belt at the same time if it is cracked or worn.

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.

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.
