The Renault F4R 736 is a 1,998 cc, inline‑four petrol engine produced between 1998 and 2002. It features a dual overhead camshaft (DOHC) and 16 valves, delivering outputs around 100 kW (136 PS) and 180 Nm of torque. Its design prioritized a balance of performance and refinement for sportier models, using multi — point fuel injection for precise metering.
Fitted to models such as the Mégane I Coupe and Laguna I, the F4R 736 was engineered for responsive driving dynamics and spi…
Production years 1998–2002 meet Euro 2 standards .
The Renault F4R 736 is a 1,998 cc inline‑four petrol engine engineered for sporty compact and mid-size hatchbacks and coupes (1998-2002). It combines multi-point fuel injection with a dual overhead camshaft to deliver smooth, high-RPM power delivery. Designed to meet Euro 2 standards, it balances performance with adequate refinement for its vehicle class.

The Renault F4R 736 was used across Renault's Mégane and Laguna platforms with transverse mounting. This engine received platform-specific adaptations-minor ECU mapping differences between Mégane Coupe and Laguna-and no significant facelift revisions during its production run. All adaptations are documented in OEM technical bulletins.
Engine Finders UK Ltd, which operates EngineCode.uk, can pass your enquiry to engine suppliers in the UK. The service is for vehicles in the United Kingdom, with UK delivery or fitting. This is a commercially connected service, and sending an enquiry does not confirm diagnosis or compatibility.
Diagnostic reminder: If a technician has recommended replacing the engine, you can send an enquiry to engine suppliers in the UK. Confirm the diagnosis first: an engine-code record does not diagnose a fault.
The F4R 736's primary reliability risk is timing belt tensioner pulley failure, a common issue across its production run. Renault workshop data indicates this is the most frequent cause for timing-related repairs. Ignoring the 60,000 km replacement interval can lead to catastrophic engine damage, making strict adherence to the schedule critical.

The most common questions about engine codes, what they mean, how to find them and how this database works
The F4R 736 is generally reliable with proper maintenance. Its main Achilles' heel is the timing belt system; failure to replace the belt and tensioner at 60,000 km can result in catastrophic engine damage. With timely belt changes and basic upkeep, these engines can easily reach 200,000 km or more.
The most frequent issues are timing belt tensioner/idler pulley failure, carbon buildup in the throttle body causing idle problems, coolant leaks from aging plastic components, and ignition coil pack failures. Adhering to the timing belt replacement schedule is the single most important maintenance task.
The F4R 736 was primarily used in the sportier variants of the first-generation Renault Mégane Coupe (1998-2002) and the first-generation Renault Laguna I (1998-2002), typically in 16V and Initiale trim levels, offering enhanced performance over the base engines.
Yes, modest gains are possible. Common modifications include a performance exhaust, air filter, and ECU chip remap, yielding around 15-25 additional PS. Significant power increases require internal modifications, which are often not cost-effective. The DOHC head responds well to tuning.
Fuel economy is reasonable for its performance. Expect around 9.5 L/100km (30 mpg UK) in combined driving for a Mégane Coupe or Laguna. Highway cruising can drop consumption to around 7.5 L/100km (38 mpg UK), while city driving may see figures closer to 12.0 L/100km (24 mpg UK).
Yes. The F4R 736 is an interference engine. This means that if the timing belt were to fail or jump, the pistons will contact the valves, causing severe internal engine damage. This makes adhering to the 60,000 km timing belt replacement interval absolutely critical.
Renault originally specified a 10W-40 mineral or semi-synthetic oil meeting CCMC G5 standards. Modern equivalents meeting ACEA A3/B3 are perfectly suitable. A 5W-40 fully synthetic can also be used for better cold-start protection and extended drain intervals.
