Peugeot TU5JP4 Engine Specs

The Peugeot TU5JP4 is a 1.6-liter naturally aspirated inline-four petrol engine produced from 1991 to 2015, one of the longest-serving and most widely used engines in PSA's history, found across an extraordinary range of Peugeot and Citroën models including the 206, 207, 306, 307, 308, 406, 407, Partner, and 806, as well as the Citroën Xsara, Xsara Picasso, C4, C5, Berlingo, Xantia, ZX, and Evasion. Few engines in this database have powered as many distinct model generations across as long a production span.

Producing 110hp and 147Nm of torque from 1,587cc, the TU5JP4 uses a DOHC 16-valve head (an upgrade over the simpler SOHC TU3JP) and a compression ratio of 10.2:1, with conventional multi-point fuel injection keeping the design straightforward and inexpensive to maintain. This mechanical simplicity - no turbocharger, no direct injection - combined with genuinely good smoothness for a naturally aspirated four-cylinder of its era, made the TU5JP4 one of PSA's most trusted and widely used mainstream engines for well over two decades.

Given its extraordinarily long and varied production run, confirming the exact production year and specific application is worthwhile before assuming parts compatibility, since minor revisions were made across the engine's decades in service. Reliability is generally strong, benefiting from the fundamentally simple, well-proven architecture and PSA's extensive refinement over such a long production period. The timing belt is a critical, interference-engine component that must be replaced strictly on schedule along with the water pump. Some higher-mileage examples develop minor oil leaks from valve cover or crankshaft seals, generally inexpensive to address. Spark plugs and ignition components should be replaced according to schedule to maintain smooth running and fuel economy. Given the engine's now-advancing age across the used market and its huge production numbers, parts availability and mechanic familiarity remain excellent across Europe and beyond.
