The Ford GSH is a 1,498 cc, inline — three turbocharged petrol engine produced between 2019 and 2023. It features direct fuel injection, variable cam timing (Ti — VCT), and a compact turbocharger, delivering 96 kW (130 PS) and 200 Nm of torque in standard tune. This engine was engineered for responsive low — end performance and high fuel efficiency in Ford’s compact vehicle lineup.
Fitted to models such as the Ford Fiesta (Mk7.5), Focus (Mk4), and Puma (Mk1), the GSH 1.5L EcoBo…
Production years 2019–2023 meet Euro 6d-Full standards .
The Ford GSH is a 1,498 cc inline-three turbocharged petrol engine engineered for compact passenger vehicles (2019–2023). It combines direct fuel injection with Ti-VCT variable cam timing and turbocharging to deliver responsive low-RPM torque and strong fuel economy. Designed to meet Euro 6d-Full emissions standards, it serves as a modern, downsized powertrain for city and suburban driving.

The Ford GSH 1.5L EcoBoost was used across Ford's Mk7.5 Fiesta/Mk4 Focus and Mk1 Puma platforms with transverse mounting. This engine received platform-specific adaptations-shorter intake manifolds in the Fiesta and enhanced torque mounts in the Puma-and from 2021 the facelifted models adopted revised timing components, 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
Aftermarket ECU tuning is common on the GSH 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.
Key issues include timing chain tensioner wear (especially pre-2021), turbo wastegate sticking, intake carbon buildup, and catalytic converter degradation. These are documented in Ford service bulletins and supported by DVSA MOT failure data. Regular maintenance, correct oil use, and prompt attention to warning rattle or misfires help prevent major repairs.
The GSH 1.5L EcoBoost was used in the Ford Fiesta (Mk7.5), Focus (Mk4), and Puma (Mk1) from 2019 to 2023. It was available in mid-to-high trim levels and was paired with either a 6-speed manual or 7-speed Powershift automatic transmission. All applications met Euro 6d-Full emissions standards.
Aftermarket ECU tuning is common on the GSH 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.
Excellent for a turbo petrol engine. In combined driving, expect 6.2–7.0 L/100 km (40–45 mpg UK). Highway driving improves to ~5.5 L/100 km (51 mpg UK), while city use can range from 7.5–8.5 L/100 km (33–37 mpg UK). Real-world consumption depends heavily on driving style, with tuned or aggressive driving reducing efficiency.
Yes. The GSH 1.5L EcoBoost is an interference engine. If the timing chain fails or jumps, pistons can contact open valves, resulting in bent valves or cylinder head damage. Immediate attention to any timing chain rattle is essential to prevent catastrophic engine failure.
Ford specifies 5W-30 synthetic oil meeting WSS-M2C946-D standard. This formulation ensures proper lubrication of the turbocharger and timing chain system. Oil should be changed every 15,000 km or annually, whichever comes first, to maintain reliability and prevent deposit formation.
