The engine code is essential for ordering parts, diagnosing issues, and verifying compatibility. It is not the same as the VIN or chassis number. This guide shows exactly where to find it - by model and engine type - using official Renault and DVLA sources
A unique identifier stamped on the engine block or cover used for parts and service.
The vehicle identification number that holds encoded vehicle and engine information.
The chassis or frame number used for registration and legal identification.
Locate the engine code on the front timing cover, near the camshaft housing. It is stamped into the metal or on a white label near the timing chain housing.
The engine code is located on a label attached to the intake manifold or camshaft cover. It reads "H5F" followed by variant numbers.
Open the hood and look at the front of the engine. The code is on a white label near the timing cover. Confirm "K9K" for diesel; petrol models show "H5F" or "F4R".
The engine code is cast into the front of the cylinder block, near the thermostat housing. Look for "F4R" followed by variant numbers.

Renault manufactures engines at multiple facilities across Europe and beyond.
Renault produces over 300,000 engines per year. Note the steady decline in Diesel production due to Euro 6d regulations, while Hybrid and electric integration rises rapidly.
Note: Diesel production has declined steadily due to Euro 6d and WLTP regulations (Regulation (EC) No 715/2007). Hybrid and electric integration rising rapidly.
Strategic partnership since 1999. Engine sharing across the alliance includes K9K diesel, TCe petrol engines, and E-Tech technology.

The most common questions about engine codes, what they mean, how to find them and how this database works
A Renault engine code (e.g., K9K, F4R, H5F) identifies the engine family, fuel type, displacement, and generation. Letter prefix indicates family (K = diesel, F = petrol, H = TCe petrol). Numbers indicate displacement and variant. Source: Renault Technical Documentation
Yes, but production is declining. The K9K dCi diesel engine is still used in some Clio and Captur models (2024 UK). However, Renault plans to phase out diesel by 2030 in line with EU emissions targets. Source: Regulation (EC) No 715/2007
The K9K 1.5 dCi is widely regarded as Renault's most reliable modern engine when maintained properly. The F4R 2.0 petrol is also durable. Avoid early 1.2 TCe engines due to oil consumption issues.
Most modern Renault engines use timing chains. The K9K diesel and newer TCe engines have chains. Some older F-series engines used belts requiring replacement every 120,000 km.
Yes, the K9K 1.5 dCi is generally very reliable with proper maintenance. Common issues include EGR valve clogging and DPF problems in urban driving. Regular oil changes critical for longevity.
On most Renault engines, the code is stamped on the front timing cover or on a label near the camshaft housing. Also check the V5C logbook under 'Engine Number'.
On the UK V5C registration document, look for the 'Engine Number' field (not VIN). This matches the engine code (e.g., K9K). If the engine was replaced, this may not reflect the current unit.
dCi (Diesel Common injection) = diesel engines with common rail injection. TCe (Turbo Control efficiency) = turbocharged petrol engines with direct injection. Both use turbocharging but different fuel types.
Yes. The engine code (e.g., K9K) is required for ordering correct parts (ECU, turbo, injectors). Using VIN alone can lead to errors. Always verify with the physical engine code.
Yes. High-performance engines (RS models) or engines with known issues (early 1.2 TCe) can increase premiums. Insurers use engine type to assess risk. Always declare correct engine code.
The K9K 1.5 dCi can last 200,000+ miles with proper maintenance. Regular oil changes every 12,000 miles critical. EGR and DPF maintenance important for urban drivers.
Newer TCe engines (H5F, H4J) are generally reliable. Early 1.2 TCe (H5F) had oil consumption issues. The 1.3 TCe (co-developed with Mercedes) is more robust. Always check service history.
Yes. Renault's E-Tech hybrid system is used in Clio E-Tech, Captur E-Tech, and Megane E-Tech. Combines petrol engine with electric motors for improved efficiency.
Yes, but must be declared to DVLA. Changing engine code may affect MoT, insurance, and emissions compliance. Ensure the replacement engine meets Euro emissions standards for your vehicle.
Dacia uses many Renault engines including K9K dCi, TCe petrol engines, and the 1.0 TCe. These are often detuned or simplified versions for cost-effective applications.
Positions 4–7 of the VIN indicate engine type. Use a Renault-specific VIN decoder for accurate information. The VIN is found on the windscreen, door jamb, or V5C.
Renault Zoe and other EVs are generally reliable. Battery degradation is the main concern (typically 10-15 years). Electric motors have fewer moving parts than ICE engines.
Renault typically recommends 5W-30 or 5W-40 fully synthetic oil meeting RN0700 or RN0710 specifications. Always check your owner's manual for the specific requirement for your engine code.
Use Renault Service Information or Renault Technical Documentation. Public data also available in EU type-approval documents and owner's manuals.
