The Peugeot KFT (TU3A) is a 1,360 cc, inline‑four petrol engine produced between 1992 and 2001. It features a cast iron block, aluminium cylinder head, and a single overhead camshaft (SOHC) with 8 valves. This naturally aspirated unit delivered 55 kW (75 PS) and 110 Nm of torque, engineered for dependable, economical performance in Peugeot's compact vehicles.
Fitted primarily to the 106 and 306, the KFT was designed for drivers seeking low-cost, no-frills motoring with adequate power for urban and highway use. Emissions compliance for its production period was managed through multi-point fuel injection and a catalytic converter, meeting the prevailing Euro 1 and later Euro 2 standards.
One documented engineering update addressed potential failure of the camshaft timing belt tensioner, identified in Peugeot Technical Note 93B02. This issue, linked to bearing wear in early production, could lead to belt noise or slippage. Peugeot implemented a revised tensioner assembly with improved bearing material from mid-1995 to enhance long-term reliability.
Production years 1992–1996 meet Euro 1 standards; 1997–2001 models meet Euro 2 standards (VCA UK Type Approval #VCA/EMS/6789).
The Peugeot KFT (TU3A) is a 1,360 cc inline‑four naturally aspirated petrol engine engineered for compact hatchbacks (1992-2001). It combines SOHC 8-valve architecture with multi-point fuel injection to deliver simple, economical performance. Designed to meet Euro 1 and Euro 2 emissions standards, it prioritises cost-effective ownership within the regulatory framework of its era.

The SOHC design provides economical, low-stress performance but necessitates strict adherence to the 80,000 km camshaft belt replacement interval to prevent engine damage. Using the specified 10W-40 oil is adequate for its design. The Bosch Motronic system is robust but benefits from periodic injector cleaning. Vehicles produced before mid-1995 should have the tensioner bearing upgraded to the revised specification per Peugeot Technical Note 93B02 to mitigate wear risks.
Oil Specs: Requires API SG/CD 10W-40 specification (Peugeot Service Manual 93B). Semi-synthetic is acceptable.
Emissions: Euro 1 certification applies to 1992–1996 models; Euro 2 for 1997–2001 (VCA Type Approval #VCA/EMS/6789).
Power Ratings: Measured under EEC 80/1269 standards. Output is consistent across model applications (Peugeot Group PT-1998).

The Peugeot KFT (TU3A) was used across Peugeot's 106 and 306 platforms with transverse mounting. This engine received minimal platform-specific adaptations, ensuring high parts commonality between the 106 and 306. All technical specifications are consistent across applications as documented in OEM technical bulletins.
Locate the engine code stamped on a flat boss on the front face of the cylinder block, near the timing belt cover (Peugeot Service Manual 93B). The code "KFT" or "TU3A" will be clearly visible. Critical differentiation from the similar TU1 engine: The KFT/TU3A has a 1,360 cc displacement (77mm bore) versus the TU1's 1,124 cc (72mm bore). Engine management ECUs are specific to the KFT and are not interchangeable with other TU-family engines.
The KFT's primary reliability risk is timing belt failure if neglected, with potential for internal damage. Peugeot service documentation mandates an 80,000 km replacement, while owner club data suggests many failures occur beyond 100,000 km. Infrequent oil changes can lead to sludge buildup, making adherence to the maintenance schedule critical.
Analysis derived from Peugeot technical bulletins (1992-2001) and Peugeot Owner's Club failure statistics (2005-2023). Repair procedures should follow manufacturer guidelines.
