Engine Renault F4Rt

The Renault F4Rt 2.0-liter turbo engine was produced at the Cleon plant from 2001 to 2016 and was installed on charged versions of such popular models as the Laguna, Megane and Espace. The Megane RS sports coupe was equipped with forced versions of this engine up to 275 hp.

In 2001, a 16-valve 2.0-liter turbo engine debuted on the Avantime minivan. As a basis, the designers took the well-known atmospheric unit F4R and remade the cylinder head for it, installed other camshafts, a reinforced connecting rod piston group, removed the phase regulator and, of course, equipped it with a turbine: in the usual version, there is a TwinScroll MHI TD04 turbocharger. The in-line cast-iron 4-cylinder block and timing belt drive remained unchanged.

Charged modifications of Renault Megan were equipped with forced versions of such an engine. On the Megane II RS, this turbo engine developed from 225 to 230 hp and 300 to 310 Nm of torque. On Megane III RS there were modifications of 250, 265, 275 hp with torque from 340 to 360 Nm.

F-series family: F3P, F4P, F7P, F2R, F3R, F4R, F4Rt, F5R, F7R, F1N, F3N.

Disadvantages of the Renault F4Rt engine

• The turbine in this engine is not very reliable and runs normally up to about 150 thousand km, then a radial play of the rotor often appears and it starts to drive the lubricant into the exhaust. Sometimes it is ruined by leaks due to a rupture of the sealing ring of the oil supply tube.
• After 150,000 km of run, it is not uncommon for a lubricant consumption of about 1 liter per 1000 km. In addition to the turbine, the reason for this may be stuck rings or hardened caps.
• This is a typical French power unit and is known for frequent electrical failures. Its weak points include ignition coils, a lambda probe, an ECU and a crankshaft sensor.
• The culprit for floating speeds is usually throttle or injector contamination, but also often the cause is a violation of the tightness of numerous intake pipes.
• Lubrication leaks regularly occur here: from under the valve cover, through the oil separator, from the turbine bypass valve or through the seals, especially from the crankshaft seals.
