Radiator
The radiator of the S85 is divided into an upper
and a lower water tank. The lower water tank
serves the purpose of cooling the coolant from
the cylinder side 1 - 5 while the upper tank is
responsible for cooling the cylinder side 6 - 10.
Due to this split design, it has been possible to
reduce the pressure drop in the radiator from
approx. 3 bar to approx. 1.4 bar.
Thermostat
Due to the two-section cooling concept, the
thermostat on the S85 has been relocated in
the return line. It is designed as a conventional
thermostat that opens at a temperature of
79 °C.
The coolant from the cylinder heads enters
the connection piece for the radiator feed and
from here it is routed both via the double O-
ring carrier into the thermostat as well as into
the coolant supply hoses.
