How long is the lifespan of the Teana 2.5V6 engine?
2 Answers
If used and maintained properly, this engine can last up to 500,000 kilometers without issues. The Teana is a mid-sized car under Nissan's brand, and it has been well-received by many consumers since its launch. The newer models of the Teana no longer use large-displacement naturally aspirated engines. Instead, they are equipped with two types of engines: one is a 2.0-liter naturally aspirated engine, and the other is a 2.0-liter turbocharged engine. Additional information: Below is an introduction to the two engines used in the newer models: 1. The 2.0-liter naturally aspirated engine in the new Teana: It has a maximum power of 117 kW and a maximum torque of 208 Nm. The engine reaches its maximum power at 6,000 rpm and its maximum torque at 4,400 rpm. This engine is equipped with a dual C-VTC continuous variable valve timing system and direct fuel injection technology, and it features an aluminum alloy cylinder head and block. It is paired with a CVT transmission. 2. The 2.0-liter turbocharged engine in the new Teana: It has a maximum power of 185 kW and a maximum torque of 380 Nm. The engine reaches its maximum power at 5,600 rpm and its maximum torque at 4,000 rpm. This engine is equipped with a dual C-VTC continuous variable valve timing system and variable compression ratio technology. It is also paired with a CVT transmission.
My 2009 Teana 2.5 V6 is still running strong at 180,000 km. The lifespan of this engine mainly depends on maintenance - I've seen one with 350,000 km still running fine at my friend's shop. Always use full synthetic 5W-30 oil and change it every 7,500 km on schedule. The transmission fluid change every 60,000 km is particularly crucial. Avoid hard acceleration during cold starts, and don't rev hard until the engine reaches operating temperature. If you see blue smoke from the exhaust, check the valve seals immediately - this is the V6 engine's biggest weakness. For city driving, 200,000 km is easily achievable with proper care. If frequently driven on highways with good maintenance, 300,000 km is quite common. Actually, Japanese engines are designed for over 250,000 km - it all comes down to how well you maintain it.
