The Range Rover K 1.8 is a 1,796 cc, inline‑four naturally aspirated petrol engine produced between 2002 and 2006. It features multi — point fuel injection, a single overhead camshaft (SOHC), and 16‑valve architecture. In standard form it delivered 85 kW (116 PS) and 160 Nm of torque, prioritising fuel economy and reliability over performance.

All production years 2002–2006 meet Euro 3 emissions standards .
The Range Rover K 1.8 is a 1,796 cc inline‑four naturally aspirated petrol engine engineered for entry-level luxury SUV applications (2002–2006). It combines multi-point fuel injection with SOHC valvetrain to deliver predictable throttle response and serviceability. Designed to meet Euro 3 standards, it prioritises cost-effective ownership over high performance.

The Range Rover K 1.8 was used exclusively in the L322 platform with longitudinal mounting and was never offered in North America or UK domestic markets. This engine was reserved for select European and Asian markets seeking lower taxation brackets. Platform-specific adaptations included a simplified intake manifold and reduced ancillary load to match the lower output. No facelift revisions affected core architecture, though from mid-2004 the cooling control strategy was updated per TSB‑02‑18‑04. All adaptations are documented in OEM technical bulletins.
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.
Field reports and technical service bulletins highlight component wear patterns under high-load operation. Adherence to manufacturer service intervals and approved fluid specifications is critical for long-term reliability.

The most common questions about engine codes, what they mean, how to find them and how this database works
The K 1.8 is mechanically simple and reliable if maintained properly. Its main vulnerability is timing belt failure if service intervals are missed. Using correct 10W-40 oil and replacing the belt every 120,000 km or 10 years greatly improves longevity. It was only sold in limited markets and is uncommon today.
The most frequent issues are timing belt failure due to age/mileage, oil sludge from extended oil changes, coolant overheating under load in early builds, and vacuum leaks from brittle hoses. These are documented in Land Rover TSB‑02‑18‑04 and TIS updates.
This engine was only used in the L322 Range Rover (2002–2006) as a base petrol option in select European and Asian markets. It was never sold in the UK, North America, or Australia. All applications are Euro 3-compliant petrol models.
Minimal tuning potential exists. The SOHC architecture, low compression, and basic engine management limit gains. Mild intake/exhaust modifications may yield +5–8 PS, but aggressive tuning is impractical due to structural and thermal constraints. Not a common tuning candidate.
Official NEDC combined is ~9.8 L/100km (29 mpg UK), but real-world mixed driving typically yields 10–12 L/100km (24–28 mpg UK). Highway cruising can achieve ~8.5 L/100km (33 mpg UK), while city driving may exceed 13 L/100km (22 mpg UK), especially with air conditioning use.
Yes. The K 1.8 is an interference design. If the timing belt fails, pistons will contact open valves, causing severe internal damage. This is why the 120,000 km or 10-year belt replacement is critical.
It requires Jaguar Land Rover STJLR.03.5001 specification oil, typically SAE 10W‑40 mineral or semi-synthetic. This is essential for sludge prevention and bearing protection. Do not substitute with generic ACEA oils—only JLR-approved formulations are validated.
