Is the Teana equipped with a timing belt or a timing chain?
2 Answers
Teana is equipped with a timing chain. The main function of the engine timing belt is to drive the engine's valve train, ensuring that the engine's intake and exhaust valves open or close at the appropriate time to guarantee normal air intake and exhaust in the engine cylinders. The chain-driven method offers reliable transmission, excellent durability, and space-saving benefits. The entire system consists of components such as gears, chains, and tensioners. The Teana's dimensions are 4868mm in length, 1830mm in width, and 1490mm in height, with a wheelbase of 2775mm. The interior of the car is equipped with features such as a multifunction steering wheel (with paddle shifters), ESC body stability control system, and an LCD display screen (with navigation function).
As an auto mechanic, I've worked on many Nissan Teana models, and they all use timing chains instead of timing belts. Chains are more durable, typically lasting the entire lifespan of the vehicle, unlike belts which need replacement every few tens of thousands of kilometers, often bringing additional costs and hassles. The chain system is designed to be more robust, especially under prolonged operation or high-temperature conditions, reducing the risk of engine failure. However, chains aren't perfect either—if the engine ages or lacks proper lubrication, they may produce noise or wear out. So, I recommend car owners regularly check and maintain oil changes to prevent chain stretching. Overall, chains make maintenance easier, offering higher reliability, especially for daily commutes and long-distance driving.
