Small displacement 1.1L engines can be installed on Golf and Jetta models (1043 cm3) and 1.3 l (1272 cm3), which are identical in design.
The engine has a valve train with an overhead camshaft (HE IS WITH). The camshaft is driven from the crankshaft by a toothed belt. The crankshaft rotates in five main bearings; middle bearing shells have thrust surfaces and act as thrust half rings.
The oil pump is housed in a separate housing bolted to the front of the cylinder block and is driven directly from the crankshaft.
The coolant pump is located at the front of the cylinder block and is driven by the camshaft timing belt.
The cylinder head is designed according to the principle "through flow" working mixture, i.e. intake and exhaust manifolds are located on opposite sides of the head (the exhaust manifold is located in front, and the intake manifold is located at the rear relative to the car).
The camshaft rotates in three bearings located on the cylinder head and acts on the valves with levers supported by adjusting ball head bolts.
The ignition distributor is located horizontally at the rear of the cylinder head and is driven directly from the camshaft.
Most repairs (e.g. removal of the camshaft drive belt, cylinder head, cooling pump) can be done without removing the engine from the car. It is only necessary to remove the engine for major repairs to the cylinder block.
