How often should the timing belt of Nissan X-Trail be replaced?

The timing belt of Nissan X-Trail needs to be replaced every 100,000 kilometers. The main function of the timing belt in Nissan X-Trail's engine is to drive the engine's valve train, ensuring that the intake and exhaust valves open and close at the appropriate times to allow normal air intake and exhaust in the engine cylinders. The Nissan X-Trail is a compact SUV equipped with a 2.0L 151 horsepower L4 engine and a CVT continuously variable transmission (simulating seven gears). The engine has a maximum power output of 111kW and a maximum torque of 194Nm. The Nissan X-Trail features a naturally aspirated intake system, with a top speed of 183km/h and a minimum ground clearance of 208mm.
As a veteran owner who has driven three X-Trails, I have a lot to say about the timing belt issue. The maintenance manual for my 2016 2.5L X-Trail states that the belt should be replaced at 100,000 kilometers, but the mechanic found cracks in the belt at just 80,000 kilometers. Rubber parts aging isn't something you can judge solely by the manual, especially for those of us who frequently drive on mountain roads—belt wear is much faster. I recommend checking it at 70,000 to 80,000 kilometers, and if you hear a ticking noise from the engine, be extra cautious. When replacing the belt, it's best to replace the water pump and tensioner pulley as well. Although it costs an extra thousand or so, it avoids having to open the engine a second time. Last time, my neighbor's X-Trail had its belt snap, which damaged the valves, and the repair bill went straight into the tens of thousands.
In our repair shop, we deal with the X-Trail every day. The belt replacement cycle for this model depends on the specific variant. For the older X-Trail with the QR25 engine, the belt typically needs replacement at around 80,000 to 100,000 kilometers. However, the newer 1.5T three-cylinder KR15 engine uses a timing chain, which doesn't require replacement for the lifetime of the vehicle. The method to determine this is simple: open the engine hood, and if you see a black plastic cover on the left side, that's the belt. During maintenance, be aware that the idler pulley is prone to abnormal noises, and the original Gates belt kit is the most reliable. Here's a common misconception to note: if there's still a squeaking sound during cold starts after replacing the belt, it's usually due to aging of the alternator belt—don't be fooled by unscrupulous shops into opening the engine cover a second time.
A friend who works in automotive design told me that the replacement cycle for Nissan's belts should consider three factors: first is mileage, with the QR25 engine recommending no more than 90,000 kilometers; second is age, as rubber begins to harden after five years; and lastly, the driving environment—vehicles frequently driven in dusty construction sites or often at high RPMs should replace them earlier. For my 2018 X-Trail, which has been parked in an underground garage year-round, the belt condition was still acceptable at 90,000 kilometers during inspection, but the tensioner was leaking oil. If more than three transverse cracks are found on the inner side of the belt, or if the edges appear jagged like they've been gnawed, replacement is necessary even if the mileage hasn't been reached.
