Don, this is sheer idiocy.
Excess heat can damage an engine, much as it can burn your house down. Out
of a fear of heat would you remove the furnace from your house? Some heat
is absolutely essential for optimal operation. Your house probably wants
somewhere between 65 and 75F; your engine needs 175-195F or 80-90C.
The minimum temperature is maintained by the thermostat restricting the
flow of coolant to the radiator until the thermostat's opening temperature
is reached; it has NO effect on overheating, unless it sticks shut which
happens RARELY (I have never seen a thermostat stuck shut in a Peugeot in
35 years--when they fail they usually stick open.)
Have you also defeated the electromagnetic fan clutches on your engines,
causing the fans to run full time, pulling cold air through the radiator,
further overcooling the engine?
Overcooling your engine produces sludgy oil, acid buildup in the oil, low
power, poor economy, and short engine life, as well as an anemic heater.
Misinformation is a worse enemy of your engine than "heat".
I apologise for being blunt, but I say this not so much for your
edification (as I suspect that your mind is made up), as for those who may
unsuspectingly follow your example and condemn their engines to a sludgy
death.
