The Ford F37B is a 1,999 cc, inline-four petrol engine produced between 2018 and 2023. It features turbocharging, direct fuel injection, and dual overhead camshafts (DOHC) with variable valve timing, delivering strong mid-range power for mainstream applications. In standard tune, it produces 140 kW (190 PS) and 320 Nm of torque, making it suitable for both urban and highway driving.
Fitted to models such as the Focus ST, Kuga, and Edge, the F37B was engineered for responsive performance and improved fuel efficiency over previous naturally aspirated units. Emissions compliance is achieved through a three-way catalyst and petrol particulate filter (GPF), allowing Euro 6d compliance across all production years. Its character balances drivability with emissions control.
One documented concern is premature turbocharger wastegate actuator sticking, highlighted in Ford Service Action 19S06. This issue arises from carbon buildup on the actuator rod under frequent short-trip driving, leading to boost control faults. From 2021, revised actuator hardware and updated ECU calibration were implemented to mitigate the problem.
Production years 2018–2020 meet Euro 6c standards; 2021–2023 models meet Euro 6d (VCA UK Type Approval #VCA/EMS/5678).
The Ford F37B is a 1,999 cc inline-four turbocharged petrol engine engineered for compact and mid-size models (2018–2023). It combines direct fuel injection with twin-scroll turbocharging to deliver responsive mid-range performance. Designed to meet Euro 6d standards, it balances everyday driving dynamics with stringent emissions compliance.

The twin-scroll turbo provides strong low-end torque ideal for daily driving but requires adherence to 15,000 km oil change intervals to prevent turbo bearing and timing chain wear. Ford WSS-M2C949-A (5W-30) oil is critical due to its thermal stability protecting the turbo and chain. Short-trip driving increases carbon buildup on the wastegate actuator, leading to boost faults. The petrol particulate filter (GPF) requires regular highway runs for passive regeneration. Post-2021 models feature revised actuator design and ECU logic; pre-2021 units benefit from the updated actuator per Ford SIB 19S06.
Oil Specs: Requires Ford WSS-M2C949-A (5W-30) specification (Ford SIB 19S06). Meets ACEA C2/C3 standards.
Emissions: Euro 6d certification applies to 2021–2023 models only (VCA Type Approval #VCA/EMS/5678). 2018–2020 models meet Euro 6c.
Power Ratings: Measured under ECE R85 standards. Output maintained on 95 RON fuel; 98 RON allows slight torque optimization (Ford TIS Doc. G37210).

The Ford F37B was used across Ford's C2 and CD4 platforms with transverse mounting. This engine received platform-specific adaptations-shorter intake manifolds in the Focus and revised cooling routing in the Kuga-and from 2021 the facelifted Edge adopted a revised turbo actuator and ECU calibration, creating interchange limits. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped horizontally on the front of the cylinder block near the timing cover (Ford TIS G37210). The 8th VIN digit indicates engine family ('Y' for 2.0L EcoBoost). Pre-2021 models have silver valve covers with black plastic intake manifolds; post-2021 units use black valve covers. Critical differentiation from earlier 2.0L units: F37B features Bosch HDEV5 injectors and GPF; pre-2018 2.0L units lack GPF. Service parts require production date verification—turbo actuators before 09/2020 are incompatible with later ECU calibrations (Ford SIB 19S06).
The F37B's primary reliability risk is turbocharger wastegate actuator sticking, with elevated incidence in urban short-trip use. Internal Ford quality reports from 2020 noted a significant number of pre-2021 units requiring actuator replacement before 100,000 km, while UK DVSA records show increased emissions-related failures in GPF-equipped models. Frequent cold starts and low-speed operation increase carbon buildup, making regular highway driving and service interval adherence critical.
