The Peugeot KF5 is a 1,587 cc, inline‑four petrol engine produced between 1997 and 2001. It features a cast iron block, SOHC valvetrain with 8 valves, and multi-point fuel injection, delivering predictable, economical performance for compact family cars. Peak power output is 66 kW (90 PS), with torque peaking at 130 Nm, suitable for light to moderate driving demands.
Fitted to models such as the 306 and 406, the KF5 was engineered for reliable, low-cost transportation. Drivers valued its mechanical simplicity and ease of maintenance. Emissions compliance for its production era was met through a basic three-way catalytic converter, achieving Euro 2 standards.
One documented concern is premature failure of the distributor ignition system, which can lead to misfires and starting difficulties. This issue, referenced in PSA Group Service Bulletin SB‑99‑05, is often linked to moisture ingress or wear in the distributor cap and rotor arm. Minor updates to the ignition coil design were implemented during its production run.
Production years 1997–2001 meet Euro 2 emissions standards applicable at time of manufacture (VCA UK Type Approval #VCA/EMS/3456).
The Peugeot KF5 is a 1,587 cc inline‑four naturally aspirated petrol engineered for compact and mid-size saloons/hatchbacks (1997-2001). It combines a robust SOHC valvetrain with multi-point injection to deliver dependable, economical performance. Designed to meet Euro 2 emissions standards, it prioritizes simplicity and serviceability over high output.

The simple SOHC design ensures low running costs but requires strict adherence to 60,000 km timing belt replacement intervals using OEM-specified components to prevent catastrophic failure. The distributor-based ignition system is susceptible to moisture and wear; caps and rotors should be replaced preventatively per PSA SB-99-05. The Bosch Motronic system demands clean electrical grounds for reliable operation. Coolant should be changed every 4 years to prevent corrosion.
Oil Specs: Requires Mineral 10W-40 meeting PSA B71 2030 specification (PSA Owner's Manual Suppl. 1998). Synthetic oils were not recommended by OEM for this engine variant.
Emissions: Euro 2 certification applies to all 1997–2001 models (VCA Type Approval #VCA/EMS/3456).
Power Ratings: Measured under DIN 70020 standards. Output figures are net ratings as installed in vehicle (PSA TIS Doc. MEC-KF-01).

The Peugeot KF5 was used across PSA's X platform with longitudinal mounting. This engine received minimal platform-specific adaptations-consistent ancillary placement across the 306 and 406-and no significant facelift revisions occurred during its production, ensuring broad parts interchangeability. All applications are documented in PSA technical bulletins.
Locate the engine code stamped on a flat boss on the cylinder block, adjacent to the starter motor (PSA TIS MEC-KF-01). The code 'KF5' identifies this specific 1.6L variant. Visually, it is distinguished by its cast iron block, the prominent distributor mounted at the rear of the cylinder head, and the absence of any turbocharger components. Critical differentiation from the later EW engine: KF5 uses a distributor ignition system, while EW engines use coil-on-plug. Service parts like timing belts and distributors are generally interchangeable within the KF family.
The KF5's primary reliability risk is distributor ignition system failure, with elevated incidence in humid climates or high-mileage vehicles. PSA technical bulletins indicate a correlation between distributor cap/rotor wear and misfire complaints, while owner reports frequently cite timing belt tensioner wear. Adherence to the 60,000 km service interval for the belt and ignition components is critical.
