Timing belt replacement: Seat Inca 1.4 (AUA)

🧭 Before you start

Remove the engine cover, air filter, ancillary belt, crankshaft pulley, lower timing cover and idler pulley, having checked the timing marks first. Release the camshaft drive belt tensioner and the main belt tensioner and take both belts off. Refit the belts, turning each tensioner anti-clockwise until both marks align, and secure the toothed belt gearwheel with the bolt and two washers as described. Remove the camshaft locking tool, check the timing marks, then refit the lower cover, a new crankshaft pulley and bolt, the ancillary belt and the air filter.

Fits: VW Jetta VI (16, 2010–2018); platform code 1.4
