The TD23 engine exemplifies the excellence of Japanese diesel engine manufacturing. Its compact size, impressive functionality, and cost-effectiveness set it apart. Despite its unassuming appearance, this engine packs a considerable punch, making it a favored choice for small trucks, crossovers, SUVs, and automobiles.
History and Evolution
Production of the TD23 began in late 1985, and by the end of 1986, these internal combustion engines were seamlessly integrated into various vehicle designs, including the Nissan Atlas. In essence, the TD23 engine succeeded and improved upon its predecessors, the “SD23” and “SD25,” inheriting their best qualities. As a result, it evolved into a high-quality Nissan diesel engine that remained in production for many years. Remarkably, it’s still manufactured in limited quantities for budget trucks and is available for custom orders.
While the era of the TD23 may be in the past, its enduring high quality, reliability, and impressive technical attributes continue to make it a competitive engine, even in today’s automotive landscape. There are no distinct profile features that set this internal combustion engine apart – it’s a typical diesel engine with an overhead valve structure and liquid cooling.
However, Nissan’s meticulous and efficient approach to its development and ongoing production has made all the difference. To reiterate, the TD23 has enjoyed popularity for over 30 years and remains highly regarded among individuals connected to the automotive industry or involved in auto repair in any capacity.

Most Common TD23 Engine Problems
- Noise and Vibration: The engine is known for being very noisy and prone to vibrations due to the timing gear drive.
- Timing Gear Wear: Gears wear out after around 250,000 km, causing the valve timing to go astray.
- Fuel System Issues: Around the same mileage, problems may arise with the pump or gear block gasket, leading to leaks.
- Electrical Problems: The oil pressure sensor and crankshaft position sensors may develop issues over time.
- Detonation: Detonation can occur due to bad fuel, leading to cracks in the bridges between the vortex chambers.
Repair and Service
Nissan’s TD23 is a shining example of a reliable diesel engine. Despite the mentioned technical characteristics, the main advantage of this internal combustion engine is its high reliability. According to reviews from TD23 operators, this engine rarely breaks down and is unremarkable in use.
The Japanese unit does not have any typical faults. In Russian realities, the following issues are most often observed:
- Leaking gaskets
- Fuel system problems due to low-quality fuel
- Increased oil consumption
Any breakdowns of the TD23 can be fixed extremely simply – just contact a specialized Nissan center or any service station.
The TD23 engine is not just a piece of automotive history; it’s a testament to the enduring quality and reliability of Japanese engineering. Its legacy lives on, and for those who appreciate a dependable diesel engine, the TD23 remains a solid choice.
