Fiat Punto Turbo

The 1.7 TD of the early models versus the 1.3 Multijet of later generations: two eras, two turbos with nothing in common

The Punto went through several decades with a profound change in its diesel engine line-up. The 1.7 TD belongs to the earliest versions, with engine codes from the 176 family, while later generations switched to the 1.3 JTD and then the 1.3 Multijet — families 188, 199, 223, 312 or 330 depending on the exact model year. These two families share absolutely no turbo components: the geometries, oil flanges and manufacturer references are entirely different.

A large number of engine codes for a 1.3 that evolved considerably

The 1.3 Multijet is the engine that demands the greatest care when it comes to identification. With more than twenty engine codes on record — from 199A2.000 à 312 B5.000 through A13DTC or Z13DTJ — the same quoted output of 75, 84, 90 or 95 hp can correspond to different turbo references. Power output alone is not enough: the engine code stamped on the block points directly to the correct manufacturer reference among the available equivalences.

New or reconditioned turbo: what the listing shows

For the 1.7 TD and the vast majority of 1.3 Multijet engines, the turbos on offer are new, sold without return of the old unit. Only the 1.3 Multijet 90 / 1.3 D Multijet 84 range has a reconditioned turbo available on an exchange basis. On the fault side, the 1.3 Multijet is prone to blockages in the oil feed line: a turbo replaced without first flushing the circuit and addressing the root cause — a clogged oil filter, degraded oil, or a fouled EGR — will fail again quickly. Persistent blue smoke, a whistling noise under acceleration, or a sharp drop in boost are the usual warning signs on this engine.
