The Renault F4P 772 is a 1,998 cc, inline‑four naturally aspirated petrol engine produced between 1996 and 2001. It features a cast iron block, aluminium 16 — valve cylinder head, and a dual overhead camshaft (DOHC) driven by a timing belt. Output is typically 88 kW (120 PS), with torque around 165 Nm, providing a balance of performance and refinement for its class.
Fitted to models such as the Laguna I (B502_), the F4P 772 was engineered for smooth, responsive motoring in mid —…
Production years 1996–2001 meet Euro 2 standards as per EU Directive 94/12/EC for registered imports).
The Renault F4P 772 is a 1,998 cc inline‑four naturally aspirated petrol engine engineered for mid-size family sedans and estates (1996-2001). It combines a cast iron block with a DOHC 16-valve aluminium head to deliver smooth, responsive performance. Designed to meet Euro 2 emissions standards, it balances drivability with environmental compliance.

The Renault F4P 772 was used across Renault's Laguna I platform with transverse mounting. This engine received no major platform-specific adaptations or facelift revisions affecting core compatibility during its production run. All applications 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 F4P 772's primary reliability risk is timing belt tensioner pulley failure, with elevated incidence in high-mileage or neglected-service engines. Renault workshop data indicates this is a critical repair item, while owner reports frequently cite ignition coil failures. Strict adherence to the 60,000 km timing belt service interval is non-negotiable to prevent catastrophic engine damage.
Analysis derived from Renault technical bulletins (1996-2001) and aggregated workshop repair data. Repair procedures should follow manufacturer guidelines.
The most common questions about engine codes, what they mean, how to find them and how this database works
The F4P 772 can be very reliable long-term if its critical service items are addressed. Its main weakness is the timing belt tensioner. Replacing the belt and tensioner every 60,000 km is absolutely essential to prevent catastrophic failure. With this and regular maintenance, these engines can easily surpass 250,000 km.
The most critical issue is the plastic timing belt tensioner pulley failure. Other common problems include failing ignition coil packs, leaking plastic thermostat housings, and valve cover gasket leaks. These are well-documented in Renault service literature and forums.
The F4P 772 2.0L petrol engine was used exclusively in the first-generation Renault Laguna (B502_), across various trim levels (RN, RT, RL, Privilege) from 1996 to 2001.
Yes, modest gains are possible. Popular modifications include a performance exhaust, high-flow air filter, and ignition upgrades. Chip tuning can yield 10-15% more power. Significant power increases require internal work or forced induction, which is complex and costly.
Fuel economy is reasonable for a 2.0L engine of its era. Expect around 9.5–10.5 L/100km (27–30 mpg UK) in mixed driving for a Laguna. Highway cruising can yield 7.0–8.0 L/100km (35–40 mpg UK). Actual figures depend heavily on condition, driving style, and gearbox ratios.
Yes. The F4P 772 is an interference engine. If the timing belt were to break or jump, the pistons will contact the valves, causing severe internal engine damage. This makes the 60,000 km timing belt service absolutely critical.
Renault originally specified a mineral 10W-40 oil. A good quality semi-synthetic 10W-40 meeting API SG/CD or ACEA A3/B3 specifications is ideal for modern use. Change intervals should be 10,000–15,000 km for optimal engine life.
