Engine Renault D4F

The 1.2-liter 16-valve Renault D4F engine was produced by the company from 2001 to 2018 and was installed on such compact models as Twingo, Clio, Symbol, as well as Dacia Logan and Sandero. There was a modification of this turbocharged power unit with a different D4Ft index.

The D-series also includes: D4Ft and D7F.

In 2001, a 16-valve version of the 1.2-liter D7F engine debuted on the Twingo. Here is the same cast-iron block for 4 cylinders, a timing belt drive, but a very unusual cylinder head: due to its compact size, 1 camshaft opens all 16 valves with bifurcated rockers. Hydraulic compensators are not provided; valve clearance adjustment is periodically required.

The first engines of the 700 series existed in two versions: 60 hp and 100 Nm or 75 hp and 105 Nm. Then came the 720 series with a different intake manifold and a larger air filter. In 2005, with the release of Clio 3, the 740 series engines acquired a camshaft with a different cam shape, due to which the power of the younger engine increased to 65 hp and 105 Nm, the older one to 79 hp and 108 Nm.

Disadvantages of the Renault D4F engine

• Such a power unit is famous for its capricious electrics and, above all, sensors. There is also an unreliable ignition coil with built-in high-voltage wires.
• According to the regulations, the timing belt changes every 120,000 km, but if it breaks earlier, the valves will be bent anyway. So it is better to periodically check its condition.
• Most often, the culprit of the noisy operation of the motor is unadjusted valves. When adjusting, remove the valve cover, intake manifold and change the gaskets.
• Also, this motor regularly worries about trifles: the owners complain about oil leaks, low service life of attachments and a gas pump that does not tolerate low-quality fuel.
