RANGE-ROVER K-1-8 engine (2002–2006) – Specs, Problems & Compatibility Database

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.

Fitted exclusively to the L322 Range Rover in select European and Asian markets as an entry-level option, the K 1.8 was engineered for urban drivability and low running costs. Emissions compliance was achieved through a three-way catalytic converter and electronic engine management, meeting Euro 3 standards across all certified markets.

One documented limitation is marginal cooling system capacity under sustained load in hot climates, noted in Land Rover Technical Service Bulletin TSB‑02‑18‑04. This can lead to elevated coolant temperatures during extended hill climbs or towing. Land Rover recommended revised thermostat calibration and auxiliary fan logic in affected vehicles from mid-2004 onward.

Compliance Note:

All production years 2002–2006 meet Euro 3 emissions standards (VCA UK Type Approval #VCA/EMS/2105).

K-1-8 Technical Specifications

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.

Practical Implications

The SOHC design offers mechanical simplicity and ease of service but delivers modest power, making it best suited for light urban use. Strict adherence to 15,000 km or 12-month oil change intervals is required to prevent sludge buildup in the oil galleries. Use only JLR-approved 10W‑40 mineral or semi-synthetic oil as specified. The timing belt must be replaced every 120,000 km or 10 years—failure results in interference damage. Cooling system performance is marginal under sustained load; vehicles used in hot climates or for light towing should have thermostat and fan logic verified per TSB‑02‑18‑04.

Data Verification Notes

Oil Specs: Requires Jaguar Land Rover STJLR.03.5001 (10W‑40) specification (Land Rover TIS Doc. J12115). Not interchangeable with ACEA A3/B4 oils without verification.

Emissions: Euro 3 certification applies to all 2002–2006 models (VCA Type Approval #VCA/EMS/2105). RDE testing not applicable for this era.

Power Ratings: Measured under ISO 1585 standards. Full output requires 95 RON minimum fuel (Land Rover TIS Doc. J12110).

K-1-8 Compatible Models

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.

Identification Guidance

Locate the engine code stamped on the front timing cover near the crank pulley (Land Rover TIS J12140). The 7th VIN digit indicates engine family ('K' for this inline-4 petrol variant). All K 1.8 units feature a black plastic cam cover with no turbo or supercharger hardware. Critical differentiation from later V6/V8 engines: smaller displacement, SOHC layout, and absence of variable valve timing. ECU part number LR008721 is specific to this application.

Identification Details

Evidence:

Land Rover TIS Doc. J12140

Location:

Stamped on front timing cover adjacent to crank pulley (Land Rover TIS J12140).

Visual Cues:

  • Black plastic cam cover
  • No forced induction components
  • SOHC cylinder head with single camshaft
Cooling System Advisory

Issue:

Marginal cooling capacity under sustained load in hot climates may cause elevated coolant temperatures.

Evidence:

Land Rover TSB‑02‑18‑04

Recommendation:

Verify thermostat calibration and auxiliary fan activation logic per Land Rover TSB‑02‑18‑04.

Common Reliability Issues - RANGE-ROVER K-1-8

The K 1.8's primary reliability risk is timing belt failure due to age or missed service intervals, with elevated incidence in vehicles exceeding 120,000 km or 10 years. Land Rover internal data (2005) indicated a measurable increase in interference damage claims in unserviced engines, while UK DVSA records show no significant emissions-related MOT failures linked to this engine. Neglect of the 120,000 km belt replacement interval is the single greatest risk factor.

Timing belt failure
Symptoms: Engine will not start, loud clatter on cranking, cam/crank correlation faults.
Cause: Aged or worn timing belt snapping or jumping teeth due to missed replacement intervals (120,000 km or 10 years).
Fix: Replace timing belt, tensioner, and idlers with OEM kit per Land Rover TIS J12110; inspect for valve/piston contact damage.
Oil sludge accumulation
Symptoms: Low oil pressure warning, rough idle, increased oil consumption, blocked oil pickup screen.
Cause: Extended oil change intervals or use of non-spec oil leading to oxidation and sludge in oil galleries.
Fix: Flush engine internals, replace oil pump pickup screen, and adhere strictly to 15,000 km oil changes with JLR-approved 10W-40 oil.
Coolant overheating under load
Symptoms: High coolant temperature warning, reduced power, steam from engine bay during hill climbs.
Cause: Marginal radiator capacity and conservative fan activation logic in early builds (pre-06/2004).
Fix: Update ECU cooling strategy and replace thermostat per Land Rover TSB‑02‑18‑04; consider auxiliary fan upgrade in hot climates.
Intake manifold vacuum leaks
Symptoms: Rough idle, lean codes, hesitation on acceleration, hissing noise from engine bay.
Cause: Brittle plastic vacuum lines and manifold gaskets hardening with age and heat exposure.
Fix: Replace all vacuum lines and intake gaskets with OEM parts; inspect PCV system for concurrent wear.
