There is a timing chain and an interference engine in every 2019 Lexus RX350 model.

Is there a timing belt or chain on the Lexus RX 350?
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.

When should the timing belt on a Lexus RX350 be replaced?
Every 60,000100,000 miles, several manufacturers advise replacing the timing belt as part of routine maintenance.
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.
What is the Lexus RX 350’s most typical issue?
The most frequent complaints across all of its model years are listed below:
- defective rain sensors
- Oil Spills.
- guiding the wandering
- Airbag Warning Light that Is On.
- The infotainment system is broken.
- A/C issues.
- transmission malfunction
- faulty oil control valves for the camshaft timing.
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.
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 ought to be largely smooth, without any cracks or missing sections.
Is there a timing belt or chain on the 2009 Lexus RX350?
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.
How much does a Lexus timing chain replacement cost?
Labor costs for The Best in Auto Repair are projected to range from $2,025 to $2,554, while parts are priced between $385 and $386. Taxes and other fees are not included in this range, nor are your particular model year or geographic area taken into account.
Does the timing chain have a warranty?
The following are often covered by the powertrain warranty: (cylinder block, cylinder heads, fuel pump, engine mounts, injection pump, manifold, oil pump, seals & gaskets, thermostat, timing chain, etc.)
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.
What is the maximum mileage for a Lexus RX 350?
The Lexus RX is a tough, dependable SUV that, with routine maintenance and prudent driving, can travel between 250.000 and 3000.000 kilometers. Your RX should last 1620 years based on 15,000 miles traveled annually before needing expensive maintenance or breaking down.
Key Points
- Those from 2014 and 2018 are the top RX models most likely to deliver a great experience. Compared to previous years, these vehicles had less reported issues.
- Six distinct recalls total for the 2016 and 2017 second-generation RX SUVs. Most frequently, severe issues with the fuel pump or airbags are raised.
- The 2010 RX, a model from the first generation, has 148 complaints filed against it. Compared to 2011, there are more than three times as many of them.
- The benchmark for the premium crossover market is set by the Lexus RX. The majority of first and second generation SUV models are incredibly dependable.
- The 2018 Lexus RX is the greatest year to have in your driveway since it costs $10,000 less than a 2020 model and probably still has factory coverage.
What is incorrect with the Lexus RX350?
Lexus RX 350 Typical Issues There have been few complaints about the older Lexus RX 350 generation, which was produced from 2007 to 2009. However, some owners have mentioned that the dashboard is vulnerable to cracking in hotter temperatures, and others have griped about leaks developing in the power steering rack and engine oil cooler pipe.
A non-interference engine: what is it?
In any engine, the pistons move up and down twice for every two crankshaft rotations, while the camshafts rotate once, opening and closing the intake and exhaust valves to permit the intake, compression, power, and exhaust strokes.
In terms of engines, interference refers to the routes taken by the pistons and valves, and more precisely, whether such routes cross.
In a non-interference engine, the piston can never “interfere with the valves” because, when it is at top dead center (TDC), it will never rise higher than a completely open valve. In contrast, a piston may share space with an open valve in an interference engine. The only thing that prevents the piston and valvethe ballerinas in the opening metaphorfrom simultaneously striving to occupy the same place is precise valve timing.
For a number of very good reasons, the majority of current engines are interference engines. Interference engines “breathe better” than non-interference engines because their valves can open earlier, close later, and open wider. Higher compression ratios are also possible with interference engines. These layouts produce less emissions, less fuel use, and more power extraction.
How much does it typically cost to replace 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:
- Starting the car is challenging.
- Engine has poor performance or is misfiring
- Noisy timing chain
- The check engine light is on.
- While idling, the engine shakes or vibrates
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.

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.
