The 2.0-liter 8-valve Renault F2R engine appeared back in 1986 and was installed in the carburetor version only on the Renault 21 model. After replacing the injection system with an electronic monopoint, EFI received the F3R index.
This is a classic for its time power unit with a cast-iron block and an aluminum 8-valve head, a two-chamber carburetor, a timing belt drive and an overhead single camshaft. There are no hydraulic lifters, so valve clearances often need to be adjusted.
F-series family: F3P, F4P, F7P, F2R, F3R, F4R, F4Rt, F5R, F7R, F1N, F3N.

Disadvantages of the Renault F2R engine
- If your engine is running intermittently: twitches, sneezes and just stalls, the first thing to do is check the carburetor. Perhaps the jets or one of the filter meshes are clogged.
- Owners very often encounter malfunctions of the ignition system. Both the coil and the distributor or the candles themselves can act up. Often, the contacts of high-voltage wires are oxidized.
- The power unit is prone to oil and coolant leaks. In addition, it is very difficult to tell you the most problematic places: it can ooze, drip and sweat anywhere.
