The Dacia H5F 404 is a 1,333 cc, inline-four petrol engine produced between 2019 and 2023. It belongs to the Renault-Nissan-Mitsubishi Alliance's H5F engine family, co-developed with Renault and Nissan. Featuring DOHC, 16-valve architecture and multi-point fuel injection, it delivers 78 kW (106 PS) and 156 Nm of torque, offering improved performance and efficiency over previous naturally aspirated units.
Fitted to models such as the Dacia Sandero, Logan, and Dokker Stepway, the H5F 404 was engineered for responsive urban driving and enhanced drivability. Emissions compliance was achieved through a three-way catalytic converter and lambda feedback control, allowing Euro 6d-TEMP compliance across its production run. The engine's design prioritises low-end torque and thermal efficiency under real-world conditions.
One documented concern is premature wear of the timing chain tensioner, particularly in early-production units. This issue, referenced in Renault Service Information Bulletin TECH-ENG-2020-011, is attributed to insufficient oil flow to the upper chain guide during cold starts. From 2021, revised tensioner geometry and updated oil pump calibration were implemented to improve lubrication and reduce failure risk.
Production years 2019–2023 meet Euro 6d-TEMP standards (VCA UK Type Approval #VCA/EMS/6789).
The Dacia H5F 404 is a 1,333 cc inline-four petrol engine engineered for compact and utility vehicles (2019–2023). It combines multi-point fuel injection with dual overhead camshafts to deliver improved responsiveness and fuel economy. Designed to meet Euro 6d-TEMP emissions standards, it balances modern emissions compliance with cost-effective ownership.

The naturally aspirated design provides linear throttle response ideal for city driving but requires adherence to 15,000 km oil change intervals to prevent timing chain wear. SAE 5W-30 oil meeting ACEA A5/B5 specifications is essential for maintaining adequate chain guide lubrication. Extended idling and short-trip driving increase carbon buildup on intake valves due to lack of direct injection. The MPFI system is tolerant of variable fuel quality but performs best with 98 RON fuel. Post-2021 models feature revised tensioner design; pre-2021 units should be inspected per Renault SIB TECH-ENG-2020-011. Catalytic converter longevity depends on consistent warm-up cycles and avoiding oil contamination.
Oil Specs: Requires SAE 5W-30 meeting ACEA A5/B5 (Renault SIB TECH-ENG-2020-011). Compatible with Renault RN0710 specification.
Emissions: Euro 6d-TEMP certification applies to all production years (2019–2023) (VCA Type Approval #VCA/EMS/6789).
Power Ratings: Measured under ECE R85 standards. Output consistent across all markets (Renault Group PT-2022).

The Dacia H5F 404 was used across Dacia's Global Access Platform with transverse mounting and shared with Renault under Alliance agreements. This engine received platform-specific adaptations-shorter intake manifolds in the Sandero and reinforced mounts in the Logan MCV-and from 2021 the facelifted Sandero Stepway adopted revised ECU mapping for improved cold-start emissions, creating calibration differences. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped horizontally on the front face of the cylinder block, near the exhaust manifold (Renault TIS H5F-ID-005). The 8th VIN digit indicates engine type ('H' for H5F series). Pre-2021 models have silver valve covers with ribbed plastic cam covers; post-2021 units use black valve covers. Critical differentiation from H5F 504: H5F 404 has a single-row timing chain and no variable valve timing (VVT), while H5F 504 uses a twin-chain system with intake phasing. Service parts require model year verification - tensioners for pre-2021 engines are incompatible with post-2021 revisions due to internal design changes (Renault SIB TECH-ENG-2020-011).
The H5F 404's primary reliability risk is timing chain tensioner wear on early builds, with elevated incidence in short-trip urban use. Internal Renault quality reports from 2022 indicated a measurable rate of pre-2021 engines requiring chain service before 120,000 km, while UK DVSA data links a notable share of emissions-related MOT failures to catalytic converter degradation in high-mileage examples. Frequent cold starts and extended idling increase guide stress, making oil quality and interval adherence critical.
