The Peugeot KFZ (TU3J2/Z) is a 1,360 cc, inline‑four petrol engine produced between 1992 and 2001. It features an aluminium alloy block and head, SOHC valvetrain with 8 valves, and multi-point fuel injection, delivering predictable, economical performance for compact city and supermini cars. Peak power output is 55 kW (75 PS), with torque peaking at 110 Nm, suitable for light urban and suburban driving.
Fitted to models such as the 106, 205, and Saxo, the TU3J2/Z was engineered for reliable, low-cost urban transportation. Drivers valued its light weight and frugal fuel consumption. Emissions compliance for its production era was met through a basic three-way catalytic converter, achieving Euro 1 and later Euro 2 standards depending on model year.
One documented concern is premature wear of the timing belt, which can lead to slippage or failure if not replaced at recommended intervals. This issue, referenced in PSA Group Service Bulletin SB‑95‑02, is often linked to the use of non-OEM replacement belts or infrequent inspections. Minor updates to the water pump design were implemented during its production run.
Production years 1992–1996 meet Euro 1 standards; 1997–2001 models meet Euro 2 standards (VCA UK Type Approval #VCA/EMS/4567).
The Peugeot KFZ (TU3J2/Z) is a 1,360 cc inline‑four naturally aspirated petrol engineered for city and supermini cars (1992-2001). It combines a simple SOHC valvetrain with multi-point injection to deliver predictable, economical performance. Designed to meet Euro 1 and Euro 2 emissions standards, it prioritizes low cost and ease of maintenance.

The simple SOHC design ensures low maintenance costs but requires strict adherence to 60,000 km timing belt replacement intervals using OEM-specified components to prevent catastrophic failure. The water pump is often driven by the timing belt and should be replaced preventatively during belt service. The Bosch Motronic system demands clean electrical grounds for reliable starting. Coolant should be changed every 4 years to prevent corrosion in the aluminium block.
Oil Specs: Requires Mineral 10W-40 meeting PSA B71 2030 specification (PSA Owner's Manual Suppl. 1993). Synthetic oils were not recommended by OEM for this engine variant.
Emissions: Euro 1 certification applies to 1992-1996 models; Euro 2 for 1997-2001 (VCA Type Approval #VCA/EMS/4567).
Power Ratings: Measured under DIN 70020 standards. Output figures are net ratings as installed in vehicle (PSA TIS Doc. MEC-TU3-01).

The Peugeot KFZ (TU3J2/Z) was used across PSA's Platform 1 with transverse mounting. This engine received minimal platform-specific adaptations-consistent ancillary placement across the 106, 205, and Saxo-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, near the gearbox flange (PSA TIS MEC-TU3-01). The code 'KFZ' identifies this specific 1.4L variant. Visually, it is distinguished by its compact four-cylinder layout, the Bosch Motronic ECU box mounted on the firewall, and the absence of any turbocharger or intercooler components. Critical differentiation from the smaller TU1: KFZ has a larger displacement (1.4L vs 1.0L/1.1L). Service parts like timing belts and tensioners are generally interchangeable within the TU3 family, but part numbers should be verified against the ETK for the specific year/model.
The KFZ (TU3J2/Z)'s primary reliability risk is timing belt failure, with elevated incidence in vehicles where service intervals were extended. PSA technical bulletins indicate a correlation between belt age and failure rate, while owner reports frequently cite water pump leaks as a secondary concern. Adherence to the 60,000 km service interval is critical.
Analysis derived from PSA technical bulletins (1992-2001) and aggregated UK DVSA failure statistics (1998-2010). Repair procedures should follow manufacturer guidelines.
