The Thermostat Housing is designed to be mounted remotely from
the engine, ideally behind and above the engine attached to some
part of the aircraft's engine mount. The purpose of the thermostat
housing is to handle the routing of coolant to either the Coolant
Pump intake or to the radiator.
The thermostat housing contains a thermostatic valve and has
fittings to connect it to the hot coolant return lines, the bypass
line and the radiator outlet line. All fittings are 37║, AN type.
The thermostat housing also provides the fill point of the coolant
system and utilizes a 20lb pressure cap to seal and maintain coolant
system pressure. An overflow port is connected to a remotely mounted
expansion tank, and two ports are provided for the system temperature
and pressure sensors.
The housing itself is machined from billet, 6160-T6 hardened
alloy and is anodized in a variety of colors (clear, black or
blue) to provide an anticorrosive finish.
The thermostat itself is an off the shelf high performance/heavy
duty automotive part. We have selected a balanced sleeve design
that provides maximum flow and is also unaffected by coolant flow
rates and pressures.
