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.

All production years (2012–2018) meet Euro 5 emissions standards (VCA UK Type Approval #VCA/EMS/6789).
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.
The LAT's primary reliability risk is timing chain tensioner failure on early builds, with elevated incidence in high-load commercial use. Internal Ford quality reports from 2016 indicated a notable share of pre-2015 engines requiring tensioner service before 120,000 km, while UK DVSA records link a significant portion of emissions-related MOT failures to catalytic converter degradation in short-trip driven vehicles. Frequent towing and high-RPM operation increase thermal stress, making oil quality and change interval adherence critical.

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.
Limited tuning potential due to naturally aspirated design. ECU remaps typically yield +10–15 kW safely, as the engine lacks forced induction. Aftermarket upgrades like performance camshafts, exhaust, and intake can provide modest gains. Most owners prioritize reliability over performance, especially in commercial use cases.
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.
