Chevrolet / Daewoo F18D3 Cylinder Head Assembly – Lacetti / Nubira / Holden Viva / Buick Excelle
This Chevrolet / Daewoo F18D3 cylinder head assembly is a brand new, factory-fresh replacement for the 1.8-litre DOHC petrol engine used across the Lacetti, Nubira, Holden Viva and Buick Excelle ranges. It is supplied with valves and camshafts fitted — intake and exhaust valves, springs, retainers, stem seals, guides and both DOHC camshafts are already installed, so the head arrives ready for installation after transferring your external components.
The F18D3 is the 1.8-litre four-cylinder engine from the GM Family II / E-TEC II architecture, produced from the mid-2000s through to the mid-2010s and fitted across Chevrolet, Daewoo, Holden and Buick-badged models in Europe, Asia, Australasia and South America. It is a DOHC 16-valve design with an aluminium cylinder head on a cast-iron block, producing 88–89 kW (120–121 PS) and 164 Nm of torque.These engines remain in daily service worldwide, and the cylinder head is a documented replacement item on high-mileage or timing failure examples.
