The Peugeot HFZ (TU1JP) is a 1,124 cc, inline‑three petrol engine produced between 1996 and 2003. It features a cast iron block, aluminium cylinder head, and a single overhead camshaft (SOHC) with 6 valves. This naturally aspirated unit delivered 44 kW (60 PS) and 98 Nm of torque, engineered for economical urban mobility in Peugeot's entry-level vehicles.
Fitted primarily to the 106 and 206, the HFZ was designed for drivers prioritising low running costs and compact dimensions. Emissions compliance for its production period was managed through multi-point fuel injection and a catalytic converter, meeting the prevailing Euro 2 standards.
One documented engineering update addressed potential failure of the timing belt tensioner spring, identified in Peugeot Technical Note 97A03. This issue, linked to material fatigue in early production, could lead to belt slippage or noise. Peugeot implemented a revised, more robust tensioner assembly from late 1998 to improve long-term reliability.
Production years 1996–2003 meet Euro 2 standards (VCA UK Type Approval #VCA/EMS/2345).
The Peugeot HFZ (TU1JP) is a 1,124 cc inline‑three naturally aspirated petrol engine engineered for city cars (1996-2003). It combines SOHC 6-valve architecture with multi-point fuel injection to deliver frugal, low-stress performance. Designed to meet Euro 2 emissions standards, it prioritises cost-effective motoring within the regulatory framework of its era.

The SOHC design provides simple, economical performance but necessitates strict adherence to the 80,000 km camshaft belt replacement interval to prevent engine damage. Using the specified 10W-40 mineral oil is adequate for its design stresses. The SAGEM injection system is robust but benefits from periodic injector cleaning to maintain idle quality. Vehicles produced before late 1998 should have the tensioner spring upgraded to the revised specification per Peugeot Technical Note 97A03 to mitigate wear risks.
Oil Specs: Requires API SG/CD 10W-40 specification (Peugeot Service Manual 97A). Mineral oil is acceptable.
Emissions: Euro 2 certification applies to all 1996–2003 models (VCA Type Approval #VCA/EMS/2345).
Power Ratings: Measured under EEC 80/1269 standards. Output is consistent across model applications (Peugeot Group PT-2000).

The Peugeot HFZ (TU1JP) was used across Peugeot's 106 and 206 platforms with transverse mounting. This engine received minimal platform-specific adaptations, ensuring high parts commonality between the 106 and early 206. 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 97A). The code "HFZ" or "TU1JP" will be clearly visible. Critical differentiation from the similar TU3 engine: The HFZ/TU1JP has a 1,124 cc displacement (72mm bore) versus the TU3's 1,360 cc (77mm bore). Engine management ECUs are specific to the HFZ and are not interchangeable with other TU-family engines.
The HFZ'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 in the valve cover, making adherence to the maintenance schedule critical.
Analysis derived from Peugeot technical bulletins (1996-2003) and Peugeot Owner's Club failure statistics (2005-2023). Repair procedures should follow manufacturer guidelines.
