System Descriptions
EW-4200D
FRESH WATER COOLING SYSTEM (cont.)
The top of the Cylinder Head has a recess for the Thermostat
(8/53). The coolant flow is held back until the Thermostat starts
to open at approximately 170 degrees F.
As long as the Thermostat is closed, the excess flow will bypass
the Cylinder and Cylinder Head, and go directly to the Reservoir
(8/56) through the Bypass Hose (15/19).
Bypass Hose
Reservoir Outlet
When the Thermostat opens, the Cylinder and Cylinder Head
flow goes through the thermostat and into the Reservoir, where
it joins the bypass flow. From there the warm coolant returns to
the Heat Exchanger (hose 16/16) where the accumulated heat is
transferred to the raw water.
Reservoir Fill Plug
The closed loop cooling system has been charged, at the factory,
with a 50/50 mixture of fresh water and permanent anti-freeze.
The Reservoir (8/54), was specially designed to prevent over
filling. The correct level is to the bottom of the threads. We
recommend checking the level each time the oil is changed.
