Reply to "Running with no thermostat"

...I have Experimented with driving Without a Thermostat, ONCE!!
I use to Drive Cross-Country in the Early '70's...A Lot! Numerous trips between Oakland, California, Chicago, Illinois and Fort Riley, Kansas.
In a '67 Mustang 390 GTA, Cruising at a Sustained 100+ Miles Per Hour.
The Radiator is small in Those Cars, forcing Me to run the Heater and FAN at FULL BLAST, to keep the Engine from Boiling Over. Yes, cooking My feet in the process, But Stayed Stable Just Below the Point of Boiling!
On one of those trips, somewhere on I-80 or I-70, Heading East in Nebraska or Kansas...I got the Brainy Idea to remove the Thermostat. Upon Continuing On My Journey, with-in just a few miles, the Coolant System Immediately BOILED OVER!
I was saved at a Small Garage in the Middle of Nowhere, with a Mechanic who cared enough to help re-Install the Thermostat. I went back on the Highway and Temps Remained 'Stable', on the Edge of Boiling Over, Me sweating in a Sauna, Loving every Minute. Had a Girl in Chi-Town, Made Oakland to Chicago in 22 Hours Flat, on a Different Sojourn! AND...'High-Test' Gasoline was $0.27 Cents a Gallon in Kansas, in 1971!! Believe it or Don't! But That's Another Story!

Back to My Point!
The Physics about Hydro-Thermal-Dynamics, that I was Later made aware of, was...'With-Out the Thermostat in Place, in the Block, The Coolant Circulates THROUGH The Engine Way TOO FAST, and Is NOT Allowed Enough Time to ABSORB the HEAT, and to Deliver That Heat to the Radiator.'

...I am Not here to sell a Thermostat. You'll do what ever You want, But The Thermostat was put there for many good reasons by Engineers who are a Lot Smarter than You or I.

By the way, I DO NOT Import The RobertShaw Thermostats. I Buy the RS 330-180F and 195F here in the USA and I Modify them Into the 333-180F/195F, Far Better than the Original Ever Was!

This week, I Just Shipped My 336th Robertshaw Hi-Flow Thermostat! You should read My Feedback, As A Seller, on Ebay!
