The cylinder head has one camshaft, eight valves and eight valve lifters with shims. The camshaft bearings are made in the head. Two camshaft bearing housings are bolted to the upper plane of the head. From above, the gas distribution mechanism is closed with a cap with an oil filler neck. A camshaft position sensor is installed in the cylinder head plug, and a pin is installed at the rear end of the shaft for detecting the shaft position sensor.
The camshaft and coolant pump are driven by a toothed belt from a toothed pulley mounted on the engine crankshaft. The tension of the belt and the direction of its movement along the pulleys is carried out by a tension roller.
