The water pump housing is integrated into the timing case. A plastic water pump gear with a steel coated hub guarantees low weight and excellent efficiency.
The integration of the short circuit line into the timing case cover simplifies the cooling system, as external hoses and hose ties are not required.
The integration of the thermostat housing in the cylinder head allows a compact construction. he cooling system is bled via a valve in the thermostat. The thermostat housing cover is made of plastic.
The seven - blade fan gear allows very high air throughput. It is driven by a visco - clutch with temperature - controlled switch - on.
A revolution limiter keeps the noise level to a minimum,
For improved drainage of the cooling system, the coolant drain plug is positioned on the cylinder block.
