Freelander - 1.8 K-Series Engine
The 1.8 K-Series Engine
The K-Series engine was launched in 1989. It won the Queen's award for Technological Achievement soon after its introduction.
Since its launch the K-Series has been progressively developed, and new engine derivatives introduced. The 117Ps 1.8 engine is an ideal petrol power unit for the Freelander; refined, responsive, and with generous reserves of torque available from low engine rpm for good performance on and off-road.

Through bolt design
The K-Series engine's great strength, durability and long term consistent performance and economy are the result of its innovative "through bolt" design. Whereas conventional designs secure the engine assembly with separate sets of fixings, the K-Series engine is connected together by a single set of long bolts which run through the engine from top to bottom. This gives it enormous strength to resist the stresses of combustion, which can otherwise eventually cause the cylinder bores to distort, reducing the engine's power and shortening its life.
Further sophistications
- Self adjusting hydraulic tappets; refinement and zero maintenance
- Camshaft drive belt with a service life of 96,000 miles
- Long life 36,000 mile spark plugs (So why are they only changed at 72,000 - Jon)
- Award winning Modular Engine Management System (MEMS); controls everything from fuelling and ignition to emission levels with split-second precision. Further enhanced for the 1.8 engine. The benefits - driveability, performance, economy and emissions control.
- Fast warm-up from high efficiency cooling system; economy.
- Advanced ultra-light-weight pistons.
- Structural cast aluminium sump; helps achieve an engine/transmission assembly beam stiffness around 3 times that of the original 1.1 and 1.4 units with pressed steel sumps - giving enhanced refinement and (via new tie bar mounting systems) better engine 'shunt' control.
