AST5090 covers engine timing applications on the Vauxhall/Opel chain driven 1.0L, 1.2L and 1.4L petrol
engines that were introduced in 2010.

The 1.2L and 1.4L engines are 4 cylinder, twin camshaft units with VVT units fitted to both inlet and exhaust
camshafts. The 1.0L engine is a 3 cylinder, twin camshaft engine with no VVT units fitted. In all cases the
chain drive is a conventional arrangement, running on both camshafts and the crankshaft.
The Crankshaft locking pin and the Tensioner locking pin are carried over from the previous ‘Z’ generation
of engines - all other tools are new to the ‘A’ engine. Note: Generation codes do not apply to Chevrolet applications
