David,
I am afraid this is incorrect. The thermostat regulates the flow through
the radiator to maintain a more or less constant operating temperature.
It starts to open at a set temperature, this is to warm up the engine
quicker as the rad is bypassed when the coolant/engine temperature is
below this temperature and the thermostat opens up fully when the
temperature is a number of degrees higher. Ideally in a properly
maintained engine, this higher temperature is never reached as coolant
that was circulating through the radiator will cool the engine down
again thus the thermostat will close a bit again. This continues untill
an equlibrium is reached, at the proper operating temperature of the engine.
The temperature should be practically the same at 50mph or at 100mph
If under heavy load the engine temperature starts to rise considerably
something is amiss with the cooling system (assuming engine, ignition,
carbs are healthy and properly adjusted).
