It isn't an on/off switch for the coolant.
Furthermore, there is a thermostat bypass that allows some coolant flow, regardless of the thermostat position.

The spec I got from the ESDI last looked like this:
Maybe they upped the opening temp (or lowered it, depending on which manual is older).
In either case, your statement about 180°F being completely closed is still wrong.

In response to the oil/water cooler, the Courage C65 car didnt even finish, according to another post in another thread, it had fluids in the pit, anyone know what happened to it?
Sorry I did not read all 6 pages of the thread, but my guess is they'd need a Huge *** radiator to handle the extra heat from the oil getting into the water, and I dont really think there is room for a bigger radiator or even running one on both sides of the car wouldnt handle the demand either.
Does anyone if the C65 overheated or it was some other mechanical problems.

At 8:01 pm (8h 15m running), Elliott Forbes-Robinson (#8-P2 Courage C65 Mazda) into the pits. Fuel only, no driver change. No coolant pressure, going behind the wall.
This is what I found on ALMS website, pit notes

oil cooling brainstorm
Hey rotorygod,
You solution of using the engine coolant to cool the oil is a good idea that is already widely used in the motorcycle industry. My 2002 Honda CBR954rr runs a coolant line from the engine around the base of the oil filter to keep the oil temperature in check. Problem solved and there is no need for a separate oil cooler.

Just got through with a track weekend At Roebling(in Savanna Ga) ambients were mid to high eighty's. Oil temps never went over 220. Coolant temps never over 210(most of the time around 190-200.(THAT WAS A SURPRISE). I have removed all protective screens from in front of the a/c and oil coolers. Running 5W30 RP--agency power pully(little underdrive). i was running lap times of 1:29's(?) 1:30---1:32 most of the time.
Earier this year with ambient temp at the same track of 100F--oil temps 230F--coolant temp 210--alll the time.
To me it seems that once ambient temps get to above mid ninety's the cooling systems start getting a little stressed. No problems with the above temps--but on the street with less airflow(i hope) redlight-to redlight--no gauges--5w/20 oil = problems. So whats new --right?

I find that the my water temps go up one degree celcius for each degree fahrenheit above 92° ambient under load.
i.e. - If my coolant temp is 92°C (196°F) at 92°F, if the ambient goes to 94°F, my coolant goes to 94°C (201°F).
Odd, but repeatable.
This also means that 110°F should really be the end of the line for me when driving the car hard. I wish I had thought about that during that 117°F mountain climb a few weeks ago...

oil cooler thermostat
Please enlighten me about this:
The oil cooling in our 8 has a thermostat which will kick in on certain temperature to flow the oil to the oil cooler right?
So, when we do oil change when engine is cold, we need not flush the oil which remain in oil cooler?
If I installed an aftermarket universal oil cooler using the sandwitch adaptor, it won't be control by the oil cooler thermostat and the oil is always flowing through to my aftermarket oil cooler? Does this setup actually better or worse?
