Cylinder Block and Liner — General Description (Renault Espace I)

Each time the engine is overhauled, the cylinder block must be thoroughly cleaned, paying particular attention to the lubrication holes. Removing the liners, pistons and connecting rods was described in previous chapters.

Pay special attention to the O-ring installed on the bottom surface of each cylinder bore, which serves as a coolant seal, and to the two additional O-rings on the diesel and V6 engines.

Diesel engine liners require more attention as they need to be changed more frequently. When doing so, be sure to include the year of manufacture of your vehicle and the engine serial number.

Three plugs are screwed into the wall of a 4-cylinder engine (tightening torque 40 Nm) and one plug - into the rear part of the cylinder block (80 Nm). The plugs are removed with a hex key.

Similar plugs are also screwed into the V6 engine block, with a screw thread diameter of either 16 mm or 18 mm. To clean the oil passages, the plugs must be unscrewed.
