How to Change the Crankshaft Pulley

Model: Renault Scenic - Years 1996-2003
Part: Engine

The function of the crankshaft pulley is to guide the belt and absorb the resonance generated by the vehicle's engine. The crankshaft pulley is secured to the engine with a bolt that needs to be unscrewed. Before removing the bolt, turn on the air compressor and wait for it to recharge. Remove the crankshaft pulley by securing the arms with the provided screws, tightening them well. Finally, clean the hub of the old pulley from rust before installing the new pulley, which should be secured by tightening the bolt at the centre of the crankshaft.

Installation of Upgraded Intercooler Radiator with Pipes

Lift the vehicle on suitable axle stands, remove the front wheels, and then the front bumper and grille. Proceed to remove the front headlights; drain the coolant, remove the intercooler radiator and the hoses connecting it to the intake system. Position the new intercooler radiator in the grille, temporarily securing it with cable ties, and mark with a marker the part of the metal that needs to be removed to allow the new hoses to pass through. Cut the marked portion of metal and apply a gasket to the edge. Remove the inner cover of the bumper and position it near the radiator to identify any interfering parts to eliminate: again, apply a gasket to the edge of the cut. Create brackets for securing the new radiator and proceed with the installation of the connecting pipes from the radiator to the intake, shaping and connecting them appropriately. Finally, reassemble the bumper, headlights, and grille.
