The Ford LAT is a 2,499 cc, inline — four naturally aspirated petrol engine produced between 2012 and 2018. It forms part of Ford's Cyclone engine family, featuring dual overhead camshafts (DOHC), variable cam timing (Ti — VCT), and sequential multi — port fuel injection. In standard tune, it delivers 129 kW (175 PS) with peak torque of 240 Nm available from 4,000 rpm, providing linear power delivery suitable for mid — size SUVs and commercial applications.

The Ford LAT is a 2,499 cc inline-four naturally aspirated petrol engine engineered for light commercial and off-road applications (2012–2018). It combines variable cam timing with sequential fuel injection to deliver smooth throttle response and consistent mid-range power. Designed to meet Euro 5 emissions standards, it prioritizes mechanical durability and serviceability in rugged operating conditions.

The Ford LAT was used across Ford's UC and T6 platforms with longitudinal mounting. This engine received platform-specific adaptations-heavier-duty cooling in the Ranger and revised intake tuning in the Transit Custom-and from 2015 the updated Everest adopted the revised oil gallery and tensioner assembly, creating interchange limits. 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 LAT delivers solid performance and durability, but early models (2012–2014) had reliability concerns, particularly timing chain tensioner failure. Later revisions (2015–2018) improved oil flow and tensioner design, making well-maintained examples robust. Regular servicing and using high-quality oil (5W-20 Ford WSS-M2C913-C) greatly enhance longevity, especially in commercial applications.
The biggest issues are timing chain tensioner failure, cylinder head warping under sustained load, intake manifold runner binding, and occasional valve cover oil leaks. These are well-documented in Ford service bulletins, particularly SIB 14S10, which addresses the tensioner redesign and maintenance recommendations for affected units.
The LAT 2.5L petrol engine was used in commercial and off-road variants including the Transit Custom (2012–2018), Ranger (2012–2018), and Everest (2015–2018). It replaced the older 2.3L Duratec and is distinct from the EcoBoost turbocharged engines. All models meet Euro 5 emissions standards throughout production.
Aftermarket ECU tuning is common on the LAT platform, but increasing boost or altering engine parameters accelerates component wear, impacts emissions compliance, and may void vehicle warranties. Any modifications should be evaluated carefully by a qualified specialist.
Moderate for a 2.5L naturally aspirated engine. In a Transit Custom (175 PS), typical consumption is ~11.5 L/100km (city) and ~8.2 L/100km (highway), or about 29 mpg UK combined. Real-world figures vary with load and driving style, but expect 25–30 mpg (UK) on mixed roads for a healthy LAT. Towing significantly reduces economy.
Yes. The LAT is an interference engine. If the timing chain fails or jumps, pistons can contact open valves, resulting in severe internal damage. While chain life is generally long, any signs of chain noise or tensioner failure must be addressed immediately to prevent catastrophic engine failure.
Ford specifies a 5W-20 synthetic oil meeting Ford WSS-M2C913-C (or newer) specification. Always use a high-detergent oil suitable for naturally aspirated engines and change it every 15,000 km or as per Ford's service schedule to prevent carbon buildup and ensure tensioner longevity.
