DECEMBER/JANUARY 2020 AFTERMARKET 21 EYEBROW www.aftermarketonline.net Alternator pulley Now is the ideal time to replace the alternator pulley, so remove the bolts securing the alternator and the water hose above it, to be able to turn the alternator in order to remove and replace the alternator pulley with Dayco ALP2409 and fit the protective cap. Refit the alternator and reattach the hose. Refit the rear timing belt case and position the new belt tensioner from the kit, paying particular attention as its slot must be located in the corresponding lug on the engine (fig.3) and then fit the new idler and tighten its bolt to 25Nm. New Dayco timing belt Using the mark painted on earlier, refit the camshaft pulley, followed by the new Dayco timing belt, ensuring its correct direction of rotation and leaving the slack section facing the tensioner. With an Allen key, first position the pointer slightly past the right-hand flange of its slot, before moving it so it points at the lug (fig.4) and tighten the belt tensioner bolt to between 24 and 27Nm, dependant on the engine variant. Turn the crankshaft through two rotations and check the engine timing remains correct. Providing it is, refit the crankshaft pulley, tightening its central bolt to 300Nm and four side bolts to 35Nm + 50°. Refit the remaining components in reverse order of their removal but check, and if necessary, replace the auxiliary belt tensioner with Dayco APV2756. However, Dayco recommends that the auxiliary belts 5PK628EE (an elastic Fig. 3 belt) and 5PK1121S are always replaced. Finally, refill the cooling system, start the engine, check carefully for leaks and ensure the radiator fan is operating correctly.
