Set of cylinder head bolts for Renault R4 4L sedan or van F4 or F6 with Billancourt engine.

TIP : Given the arrangement of the screws, it is normally necessary to use a special key or dismantle the rocker arm to intervene on the cylinder head gasket. To avoid this heavy handling, we changed the nature of the screws using hexagon socket heads. It will be imperative to tighten your screws with the torque wrench, because given the difference in length of the latter, the angular tightening is not available.
