For robustness and long life, more recent models use timing belts consisting of polyurethane and Kevlar. 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 was the timing chain installed on a Lexus RX?
Timing chains are standard on all Lexus RX350 engines from the model years 2007 through 2021. From 2007 through 2021, every Lexus RX350 engine is interference.
In a combustion engine, the timing belt (or chain) maintains the correct synchronization between the various engine parts.
Serious engine damage may result if the belt or chain strains or breaks.
Timing chains are typically rated for the lifespan of the engine, while timing belts have a suggested replacement interval, however they do need to be inspected on occasion.
Understanding the timing system in your car or a potential purchase might help you save future costs and hassles.

Has the Lexus RX350 a timing chain or belt?
The engine uses timing belts to maintain synchronization between the crankshaft and camshaft movements. Timing belts are constructed of heavy rubber that eventually deteriorates and needs to be replaced.
The 2013 Lexus RX 350, however, makes use of a timing gear. Timing gears are formed of thick metal and provide the same function as timing belts without needing to be replaced.
Follow the recommended maintenance schedule in the owner’s manual or consult a dependable mechanic to maintain your Lexus in top condition.

How much does a Lexus timing belt replacement cost?
Best in Automotive Repair Timing belt replacement for a Lexus ES300 typically costs between $784 and $1,000. While parts are priced between $421 and $543, labor costs are predicted to range between $363 and $458.
How long does a timing chain on a Lexus last?
Older cars might have a timing chain, which is comparable to a motorbike chain and has a lifespan of about 60,000 miles. For robustness and long life, more recent models use timing belts consisting of polyurethane and Kevlar. Although they can last up to 100,000 miles, it’s always a good idea to change them before that.
Should timing chains be replaced?
When should a timing chain 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.
When should a Lexus RX350’s timing belt be replaced?
Every 60,000100,000 miles, several manufacturers advise replacing the timing belt as part of routine maintenance.
Is there a timing belt or chain on a 2009 Lexus RX 350?
Because the 2009 RX 350 has a timing chain, the timing chain itself doesn’t need to be maintained. Running a car past a suggested repair until something breaks is NOT a smart approach.
A timing belt or chain is present in a 2008 Lexus RX 350.
The 2008 Lexus RX 350s have chains instead of timing belts. By the 2007 Lexus RX350s, timing belts were replaced with chains.
Which is superior, timing belts or chains?
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.
How much does repairing a timing chain cost?
Timing chains can be changed by a professional for $1,600 to $1,800 or you can do it yourself for $600 to $800. The cost is significant because it’s challenging to replace this component.
Before a timing belt breaks, is there a warning?
You should keep an eye out for certain telltale warning indications that your timing belt is likely to fail, such as ticking noises, difficulty starting the vehicle, piston misfires, exhaust smoke, excessive vibrations, and oil leaks.
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.
How do you recognize a faulty timing belt?
Your timing belt may be significantly damaged if you hear a ticking sound emanating from the engine of your car. Your car’s timing belt is connected to the crankshaft and camshaft of the engine through a number of pulleys. The connecting rods of the engine, which are connected to the pistons inside the combustion chamber, provide power. The rocker arm assembly and cylinder head valves are controlled by the camshaft, which delivers gasoline to the combustion chamber. The exhaust manifold is the next point of exit for the released gases. Your car’s timing belt may start to twitch inside the engine when it begins to wear out. This can potentially be a symptom of low oil pressure.
What occurs if a timing chain malfunctions while you’re driving?
An engine with a broken timing chain will either not start or fail while being driven. The engine won’t start if the belt is already broken since there won’t be adequate compression. The pistons will sustain damage by coming into touch with the valves if it breaks or leaps while being driven. The actual valves will bend, possibly ruining the engine.
How can timing chain failure be avoided?
- Check your timing chain cover for leaks frequently.
- Make that the engine oil is not running low.
- Avoid letting the engine get too hot; if it does, don’t drive.
Can I drive on a bad timing chain?
The timing chain expands over time, as was already mentioned. Even though you can still drive with an old timing chain, we advise replacing it as soon as you observe stretch or other signs of failure.
A faulty chain can jump many teeth or entirely break if you drive on it for an extended period of time and it continues to strain, which can seriously harm your engine’s internal components.
How long does a timing chain replacement take?
The crankshaft and camshafts in your engine are connected by a timing chain. During the combustion process inside the cylinders, camshafts accurately open and close the intake and exhaust valves. A qualified mechanic should need between 5 and 8 hours to replace the timing chain and all related gear.
What drives the timing on a 2011 Lexus ES 350: a belt or a chain?
Timing chains are included on all Lexus ES 350 engines from model years 2007 through 2021. From 2007 through 2021, every Lexus ES 350 engine is interference.
