PEUGEOT NFT-TU5JP engine (1996–2003) – Specs, Problems & Compatibility Database

The Peugeot NFT (TU5JP) is a 1,587 cc, inline‑four naturally aspirated petrol engine produced between 1996 and 2003. It features a cast‑iron block, aluminium head, DOHC valvetrain with 16 valves, and sequential multi‑point fuel injection. Peak output is 66 kW (90 PS) with 135 Nm of torque, engineered for responsive performance in Peugeot's compact and mid-size models.

Fitted to models like the 206, 306, and Partner, the NFT was designed for drivers seeking a balance of spirited acceleration and everyday practicality. Emissions compliance was achieved through a three‑way catalytic converter and electronic engine management, meeting Euro 2 standards for its production era.

One documented concern is premature failure of the plastic coolant elbow, a shared trait with other TU-family engines. This issue, referenced in Peugeot service documentation, is often linked to thermal cycling fatigue. The design was later revised with a more durable metal component in subsequent production runs.

Compliance Note:

Production years 1996–2003 meet Euro 2 standards (VCA UK Type Approval #VCA/EMS/7656).

NFT-TU5JP Technical Specifications

The Peugeot NFT (TU5JP) is a 1,587 cc inline‑four naturally aspirated petrol engineered for compact hatchbacks and vans (1996-2003). It combines a durable cast-iron block with DOHC 16-valve architecture to deliver lively performance and good drivability. Designed to meet Euro 2 standards, it balances performance with environmental compliance.

Practical Implications

The DOHC 16-valve design provides a smooth and responsive power delivery ideal for city and highway driving but requires strict 10,000 km oil changes with quality mineral oil to protect the hydraulic tappets. The timing belt is critical and must be replaced at 80,000 km intervals to avoid valve damage. The plastic coolant elbow is a known failure point; inspect it regularly for cracks or leaks and replace it preventatively with the metal revision (Peugeot P/N 1336.11) if still fitted. Use 95 RON fuel for optimal performance.

Data Verification Notes

Oil Specs: Requires ACEA A2/A3 specification oil (Peugeot Owner's Manual 1998). Mineral oils were standard for this era.

Emissions: Euro 2 certification applies to all 1996–2003 models (VCA Type Approval #VCA/EMS/7656).

Power Ratings: Measured under EEC 80/1269 standards. Output is consistent across model applications (Peugeot TIS Doc. TU5-001).

Identification Guidance

Locate the engine code stamped on a flat boss on the front face of the cylinder block, near the gearbox flange (Peugeot TIS TU5-001). The 8th VIN digit typically corresponds to the engine code ('T' for NFT). Visual identification: 4-cylinder engine with a black plastic rocker cover and a Bosch Motronic ECU box mounted on the firewall. Critical differentiation from TU5JP4: NFT (TU5JP) produces 90 PS, while TU5JP4 produces 110 PS. Service parts for the NFT are generally compatible across all 206, 306, and Partner applications from 1996-2003.

Coolant Elbow Failure

Issue:

The plastic coolant elbow (located at the rear of the cylinder head) is prone to cracking and leaking, leading to sudden coolant loss and potential engine overheating.

Evidence:

Peugeot Service Bulletin SB-99-03

Prevention:

  • Inspect the elbow regularly for signs of brittleness or cracking.
  • Replace it preventatively with the updated metal version (Peugeot P/N 1336.11) during any cooling system service.
Timing Belt Criticality

Warning:

The NFT is an interference engine. A broken timing belt will cause severe engine damage.

Evidence:

Peugeot Owner's Manual 1998

Interval:

Replace the timing belt, tensioner, and water pump at 80,000 km or 5 years, whichever comes first.

Common Reliability Issues - PEUGEOT NFT-TU5JP

The NFT's primary reliability risk is failure of the plastic coolant elbow, with elevated incidence in vehicles subjected to frequent thermal cycling. Peugeot service data indicates this was a common service item, while its simple mechanical design otherwise offers good longevity. Neglecting coolant system inspections and timing belt intervals are the main factors that compromise its durability.

Plastic coolant elbow failure
Symptoms: Visible coolant leak from the rear of the engine, rapid drop in coolant level, engine overheating warning light.
Cause: Material fatigue and cracking of the original plastic coolant elbow due to repeated heating and cooling cycles.
Fix: Replace the failed plastic elbow with the updated, more durable metal version (Peugeot P/N 1336.11).
Timing belt failure
Symptoms: Engine stops suddenly, will not restart, potential loud clattering noise on failure.
Cause: Age, mileage, or oil contamination causing the belt to snap or jump teeth on an interference engine.
Fix: Replace timing belt, tensioner, idler pulleys, and water pump as a complete kit per OEM service schedule.
Idle control valve (ICV) malfunction
Symptoms: Unstable idle, stalling, rough running, illuminated check engine light.
Cause: Carbon buildup or mechanical failure of the idle control valve, preventing it from regulating air bypass correctly.
Fix: Clean or replace the faulty idle control valve. Cleaning may be a temporary fix; replacement is often the permanent solution.
Oil leaks from rocker cover gasket
Symptoms: Oil smell, visible oil residue on the top of the engine, potential drips onto the exhaust manifold.
Cause: The rubber rocker cover gasket hardens and shrinks with age and heat, losing its ability to seal against the cylinder head.
Fix: Replace the rocker cover gasket. Ensure the mating surfaces are clean and the cover bolts are torqued to specification.
