What is the cause of the ticking sound in the Arrizo 5 engine?
2 Answers
The reasons for the ticking sound in the Arrizo 5 engine are: 1. The sound of the carbon canister solenoid valve working; 2. Aging or loose/fallen engine mounts. Taking the Arrizo 5 2020 model as an example, its body dimensions are: length 4572mm, width 1825mm, height 1482mm, wheelbase 2670mm, minimum ground clearance 129mm, and fuel tank capacity 48 liters. The Arrizo 5 2020 model is equipped with a 1.5T turbocharged engine, with a maximum horsepower of 156PS and a maximum power of 115kW, paired with a 5-speed manual transmission.
I experienced similar issues with my Arrizo 5. The most common cause of the ticking sound is excessive valve clearance. After tens of thousands of kilometers, valve component wear can produce knocking noises. It could also be a loose timing chain—when the chain skips teeth, it creates rhythmic sounds. Additionally, fuel injector operation generates ticking noises, especially noticeable during cold starts. Check if the engine oil is sufficient or too thin; insufficient lubrication increases friction noise. Don’t overlook these details. I recommend starting with simple self-checks, like listening to the source location when the engine is cold. If the noise grows louder, it could lead to internal engine damage. Getting a professional diagnosis at a 4S shop early can save you big money. Personally, I make it a habit to have mechanics listen to the engine sound during every maintenance session—prevention is better than repair.
