Character

F4Rt

"Renault 2.0 turbo petrol (Laguna II/III 2.0T and GT, Espace IV, Vel Satis, Scenic II, Megane II Sport 225/230, Megane III R.S. 250-275, Megane III TCe 180). Understressed and durable; stronger internals than the non-turbo F4R and no phaser pulley. Watch the timing belt and its rattly pulleys, rocker-cover oil leaks and ignition coils; track cars need extra cooling."

D4F

"Renault 1.2 petrol for small cars (Twingo, Clio, Kangoo, Modus, Dacia Logan/Sandero): the 8V D7F from 1996, the 16V D4F from 2000. Simple and long-lived. It has a timing belt, not a chain - change it on time because a broken belt bends the valves. Throttle-body fouling causes idle problems; D4F engines built Sep-Nov 2010 had a valve-cotter recall."
