The Ford F37A is a 1,998 cc, inline — four, overhead — valve (OHV) petrol engine produced between 1984 and 1991. It was developed as a larger — capacity evolution of the EY series, designed for enhanced torque and durability in medium — duty applications. Equipped with a single — barrel carburettor and distributor — based ignition, it delivered 62 kW (84 PS) and 150 Nm of torque, providing steady performance for commercial and family transport.

Production years 1984–1986 meet pre-Euro 1 emissions benchmarks; 1987–1991 models comply with Euro 1 standards (VCA UK Type Approval #VCA/EMS/5680).
The Ford F37A is a 1,998 cc inline-four OHV petrol engine engineered for executive sedans and fleet applications (1984–1991). It builds on the EY platform with increased displacement and updated emissions controls to meet evolving regulations. Designed for durability and smooth operation, it balances low-end torque with acceptable fuel economy for its class.

The Ford F37A was used across Ford's LX and Scorpio platforms with longitudinal mounting and no licensed external usage. This engine received platform-specific adaptations-revised carburettor tuning for automatic transmission models and enhanced cooling for taxi variants-and from 1987 the facelifted Granada Mark III adopted the Euro 1-compliant variant with updated EGR and ignition timing, creating interchange limits. All adaptations are documented in OEM technical bulletins.
The F37A's primary reliability risk is cylinder head gasket failure on pre-1986 units, with elevated incidence in high-mileage or poorly cooled applications. Ford's internal field reports from 1987 indicated over 14% of early F37A engines required head work before 140,000 km, while UK DVSA historic data shows cooling system neglect as a top contributor to engine-related MOT failures. Infrequent oil changes and thermostat faults increase thermal cycling stress, making coolant maintenance and timely gasket upgrades critical.

The most common questions about engine codes, what they mean, how to find them and how this database works
The Ford F37A is fundamentally robust, especially in post-1986 models with the upgraded MLS head gasket. Early units (1984–1986) are prone to head gasket failure under sustained load or poor maintenance. With regular servicing, proper coolant, and timely component renewal, many examples exceed 200,000 km. Its simplicity enhances longevity when basic upkeep is followed.
Key issues include cylinder head gasket failure (pre-1986), carburettor flooding or tuning drift, timing chain wear, and cooling system corrosion. These are documented in Ford service bulletins and owner registries. The Motorcraft 1V carburettor requires periodic maintenance, especially with modern ethanol-blended fuels.
The F37A engine was used in the Ford Granada Mark III (1984–1987) and Scorpio (1987–1991). It powered 2000 GL, Ghia, and Executive trims. No known cross-manufacturer usage outside Ford's European lineup.
Yes, modestly. Performance tuning includes fitting a twin-barrel carburettor (e.g., Weber 32/34), performance camshaft, and exhaust upgrade. Output can reach ~75 kW (102 PS) reliably. However, the OHV design limits high-RPM potential. Tuning should preserve reliability, especially regarding cooling and lubrication.
Typical consumption is ~10.5 L/100km (city) and ~7.8 L/100km (highway), or approximately 27 mpg UK combined. Real-world figures vary with driving style and vehicle weight. The carburetted system is less efficient than modern injection, but careful driving can achieve 25–30 mpg (UK) on mixed routes.
No. The Ford F37A is a non-interference (freewheeling) engine. If the timing chain fails, the pistons will not contact the valves, preventing catastrophic internal damage. However, immediate repair is still essential to avoid secondary issues like misfires or oil contamination.
Ford specifies SAE 10W-40 mineral oil meeting API SG standards. Change intervals should not exceed 12,000 km or annually. Using correct oil ensures proper lubrication of the camshaft, lifters, and timing chain. In high-temperature or stop-start use, more frequent changes are advised.
