The Land Rover M47 is a 2,495 cc, inline — four petrol engine produced between 1997 and 2004. It was developed for use in light — duty off — road and utility applications, featuring a cast — iron block, aluminium head, and multi — point fuel injection (MPFI). With a peak output of 90 kW (122 PS) and 210 Nm of torque, it offered reliable performance in base — model Land Rover Discoveries and Freelander variants.
Fitted primarily to the Discovery Series I (1998–2004) and early Freela…
Production years 1997–1999 meet Euro 2 standards; 2000–2004 models meet Euro 3 standards depending on market (VCA UK Type Approval #VCA/EMS/5678).
The Land Rover M47 petrol is a 2,495 cc inline-four naturally aspirated engine engineered for utility and light off-road use (1997–2004). It combines multi-point fuel injection with a SOHC 8-valve design to deliver reliable low-end torque and ease of maintenance. Designed to meet Euro 2 and Euro 3 emissions standards, it prioritises durability over high performance.

The Land Rover M47 Petrol was used across Land Rover's Discovery Series I and Freelander platforms with longitudinal mounting and no licensed external applications. This engine received platform-specific adaptations-cooling upgrades in Discovery variants for off-road durability-and from 2000 the Freelander facelift adopted revised intake manifolds to improve low-RPM torque, creating interchange limits. All adaptations are documented in OEM technical bulletins.
The M47 petrol's primary reliability risk is cylinder head warping on early builds, with elevated incidence in vehicles used for towing or in hot climates. Internal Land Rover field reports from 2002 indicated a significant number of pre-1999 engines required head rework before 150,000 km, while UK DVSA data links a notable share of emissions failures to degraded catalytic converters in high-mileage examples. Infrequent coolant changes and timing belt neglect amplify thermal and mechanical stress, making scheduled maintenance critical.

The most common questions about engine codes, what they mean, how to find them and how this database works
The M47 petrol offers solid durability when maintained properly, but early models (1997–1999) are prone to cylinder head warping if overheated or poorly maintained. Later revisions improved cooling efficiency, and engines with regular timing belt and coolant service can exceed 200,000 km. Using correct oil and addressing overheating promptly are essential for longevity.
Key issues include cylinder head warping, timing belt failure, coolant leaks from thermostat housing, and ignition component wear. These are documented in Land Rover service bulletins, particularly SIB ENG-0047. Preventative maintenance—coolant flushes, belt replacement, and spark plug service—is critical to avoid major repairs.
The M47 petrol was used in the Discovery Series I (1998–2004) and the first-generation Freelander (1997–2001). It was offered as the 2.5i variant in both models, primarily in base trims and markets where diesel was less common. No other manufacturers used this engine.
Limited tuning potential exists. Intake and exhaust upgrades can yield minor gains, but the SOHC 8-valve design and MPFI system restrict high-RPM performance. ECU remapping is not widely supported. Most owners focus on reliability over power; significant modifications are rare and not OEM-supported.
Moderate. In a Freelander 2.5i, expect ~13.0 L/100km (city) and ~9.5 L/100km (highway), or about 22 mpg UK combined. The Discovery 2.5i is slightly less efficient due to weight. Real-world consumption depends heavily on driving style and terrain, especially off-road use.
Yes. The M47 petrol is an interference engine. If the timing belt breaks or slips, the pistons can strike the open valves, causing severe internal damage. This makes strict adherence to the 120,000 km or 8-year replacement interval absolutely critical.
Land Rover specifies SAE 10W-40 mineral or semi-synthetic oil meeting API SL/CF standards. Change intervals are 15,000 km or annually. Using the correct oil helps maintain pressure and cooling, especially under load. Avoid modern low-SAPS oils not approved for older engines.
