[Spridgets] thermostat in the south......

[Mark Endicott]

So I have a question,  Just what is considered too hot?

My 1275 will run 190 to 200 on a 95+ day in Tennessee.  It doesn't boil 
(obviously) and the engine runs fine.  If it fill the radiator to the top of 
the neck it will burp out what it doesn't want but only once then it is 
fine.  I would think that 200 is OK for a cast iron block and head.  It has 
been like this as long as I have had Spridgets, over 40 years.  I run a 180 
Thermostat because I think that is the MINIMUM temp. that it should run, the 
MAXIMUM temp is controlled by the cooling system not the thermostat.  My 
thoughts have always been that if it doesn't boil it's ok.  I also use a 
75/25 mix of water/antifreeze as our winters are relatively mild and my cars 
stay in a heated garage.
