I am in the process of re-installing my intake manifold and I am wondering if I need to install the thermostat.  My '77 vette is driven only in the summer time, not in the spring or winter.

 

I want to run the engine cooler to keep the interior cooler and to run the air-conditioner more effectively. 

 

With thermostat installed last year, the temp gauge read ~ 200 °F. 

Without the thermostat, to temporarily to flush the cooling system, the temp gage read ~180 °F.

 

Any problems with doing this?

 

Thanx!

BUT, under some conditions, the unrestricted flow actually goes into and out of the radiator too fast.  The result is the coolant never cools off.  It gets through the radiator so fast it's still hot comming out of the radiator.  As a result, you can overheat.

 

Also remember when a thermostat opens at 180, it's open.  Any temp above that is a function of the heat created and the cooling system balancing out.   if the engine ran at 200 for an example,  it would still run at 200 if it had a 195, 180, or 160 thermostat.

 

I never thought that it also acts like a restrictor when it's fully open. I do not want to take a chance and have it over heat so I will reconnect it just to be on the safe side.
