Reconditioned Renault Engine on an exchange basis

Which Renault engine code matches my unit exactly?

This is the key question for any Renault engine replacement: the same model, the same engine capacity and the same quoted power output can cover several distinct engine codes — and these are not minor variants but technically different units. The four- or five-character code stamped on the engine itself — not the commercial designation — is the only reliable reference for identifying the correct reconditioned engine.

The same engine capacity, radically different engine families

The 1.5 dCi perfectly illustrates this pitfall: the family alone covers more than forty codes (K9K700, K9K702, K9K760, K9K792, K9K846…), spread across the Clio, Kangoo, Mégane, Scénic, Laguna and Trafic between 1997 and 2024. A K9K702 from a Mégane II and a K9K780 from a Kangoo III are not interchangeable without verification. The K9K perfectly illustrates this pitfall: the family alone covers more than forty codes (K9K700, K9K702, K9K760, K9K792, K9K846…), spread across the Clio, Kangoo, Mégane, Scénic, Laguna and Trafic between 1997 and 2024. A K9K702 from a Mégane II and a K9K780 from a Kangoo III are not interchangeable without verification. The 1.9 dCi belongs to the F9Q family (F9Q-670, F9Q-750, F9Q800, F9Q872…), found notably on the Laguna, Mégane and Vel Satis. The 2.0 dCi moves to the M9R family (M9R630, M9R750, M9R802…), a different architecture fitted among others to the Laguna III, Koleos and Trafic.

On the van and large-vehicle side, the 2.3 dCi (family M9T, more than twenty codes: M9T672, M9T690, M9T726, M9T880…) powers the Master and Trafic in their most recent versions. The 2.5 dCi (G9U) and the 2.2 dCi (G9T) covered the Master, Espace and Vel Satis of earlier generations. The 2.8 dCi (8140.63) and the 3.0 dCi (S9W_702, ZD3200, ZD3202) apply to the Mascott and the most powerful versions of the Master and Espace.

Petrol: TCe and 16V — engine families that must not be mixed up

On the petrol side, the 1.2 TCe belongs to the H5F family (H5F_403, H5F_404, H5F_408, H5F400, H5F 408), fitted to the Clio IV, Captur and Modus. The 0.9 TCe (H4B401, H4B_408, H4B400) is fitted notably to the Twingo III and the first-generation Captur. The 1.3 TCe (H5H_450, H5H_470, H5H_490) is the most recent engine in the range, fitted to the Kadjar, Mégane IV and Kangoo III. The 1.6 16V (K4M 854, K4M_813) and the 1.6 dCi (family R9M, R9M402 to R9M_450) are two distinct engines despite sharing the same engine capacity: their families, architectures and production years do not overlap. All engines in this range are sold as bare engines; ancillary components are not included.
