The Nissan TB48DE is a 4,757 cc, inline‑six naturally aspirated petrol engine produced between 2002 and 2007. It features a cast iron block, aluminum head, dual overhead camshafts (DOHC), and electronic fuel injection with variable valve timing. This robust design prioritized low — end torque and off — road durability for the Patrol, delivering outputs of 170 kW (231 PS) and 410 Nm.

Production years 2002–2007 meet Euro 3 emissions standards for their respective model years and markets (VCA UK Type Approval data for relevant chassis codes).
The Nissan TB48DE is a 4,757 cc inline‑six naturally aspirated petrol engine engineered for full-size SUVs (2002-2007). It combines a robust DOHC valvetrain with variable valve timing to deliver strong, linear torque for off-road and towing applications. Designed to meet Euro 3 emissions standards, it prioritizes mechanical durability and serviceability in harsh conditions.

The Nissan TB48DE was used exclusively in Nissan's Y61 platform with longitudinal mounting. This engine was fitted only to the Patrol GU facelift and received no major platform-specific adaptations. All technical specifications are consistent across its production run.
Engine Finders UK Ltd, which operates EngineCode.uk, can pass your enquiry to engine suppliers in the UK. The service is for vehicles in the United Kingdom, with UK delivery or fitting. This is a commercially connected service, and sending an enquiry does not confirm diagnosis or compatibility.
Diagnostic reminder: If a technician has recommended replacing the engine, you can send an enquiry to engine suppliers in the UK. Confirm the diagnosis first: an engine-code record does not diagnose a fault.
The TB48DE's primary reliability risk is variable valve timing (VVT) solenoid failure, with elevated incidence in high-mileage or poorly maintained examples. Nissan service data indicates this is a common cause for check engine light visits, while UK DVSA records show no systemic mechanical failures. Using the correct oil and adhering to change intervals per NTB-TB48-001 make preventative maintenance critical.
Analysis derived from Nissan technical bulletins (2002-2007) and UK DVSA failure statistics (2005-2010). Repair procedures should follow manufacturer guidelines.
The most common questions about engine codes, what they mean, how to find them and how this database works
Yes, the TB48DE is renowned for its exceptional long-term reliability and durability, especially in off-road conditions. Its simple, robust inline-six design and non-interference layout are very forgiving. Key to longevity is regular oil changes and addressing the known VVT solenoid weakness. Many examples have surpassed 400,000 km with proper care.
The most common issues are variable valve timing (VVT) solenoid failure causing check engine lights, throttle body carbon buildup leading to drivability problems, oil leaks from the valve cover or rear main seal, and coolant leaks from the thermostat housing. These are well-documented in Nissan service manuals.
The TB48DE was used exclusively in the Nissan Patrol (Y61 series) GU facelift models produced between 2002 and 2007. It was typically fitted to higher-spec variants like the Ti and ST-L.
Modest power gains are possible. Common upgrades include a performance air filter, free-flow exhaust, and ensuring the VVT system is in perfect working order. Significant power increases are limited by the naturally aspirated design. Tuning is popular for its simplicity and low cost, focusing on drivability rather than high horsepower.
Fuel economy is moderate for its size and application. In a Nissan Patrol Y61, expect around 14.0–16.0 L/100km (17–20 mpg UK) combined in real-world driving. Highway cruising can yield figures closer to 12.0–13.0 L/100km (22–24 mpg UK), depending on load and driving style.
No. The Nissan TB48DE is a non-interference engine. This means that if the timing chain were to break or jump, the pistons will not contact the valves. This design significantly reduces the risk of catastrophic engine damage from timing component failure.
Nissan recommends a high-quality mineral or semi-synthetic SAE 10W-40 engine oil. Regular oil and filter changes every 10,000 km (or 6 months) are crucial for engine longevity, especially to protect the timing chain and VVT system from sludge buildup.
