The NYB overheated on I-4 yesterday...

You know in every car I owned in Australia I simply threw the thermostat away and didn't even bother replacing it, the weather simply did not get cold enough to warrant one. I would imagine that would be true here too of the more southern states?
I know some people who had issues with over heating because the water now flowed too fast but all that needed to be done was put a restricter plate in and it worked like a charm.
 
I still believe in getting the oil up to temp that it was engineered to work at.
How does restricting water flow to the heads get the oil to heat faster? Cos of the warmer temperatures in southern climes I cant see it making much of a difference to the oil's viscosity. It's always been my understanding that winter temperatures and such was what thermostats were designed for?
 
I may be a little off but if you don't have a thermostat to restrict and control the water flow the water never get's to cool in the rad and it just boils
 
I always run a thermostat. The reasons below are an excerpt from the Allpar site and most succinctly explain why:

The thermostat controls the minimum temperature of the engine. It cannot control the maximumtemperature. The only way the thermostat can cause the engine to run too hot is if it is faulty and doesn’t open completely (or at all).It is commonly, but wrongly, thought that a cooler-running engine is better. It is not! An engine prevented from reaching proper operating temperature because the thermostat is “too cold” (opens at too low a temperature), or missing entirely, wastes fuel, wears faster, and dirties its oil faster. Starting in the late 1960s, higher-temperature thermostats—185°, 190°, 195°, and even 200°—were installed at the factory to help clean up emissions. Hotter coolant means more complete combustion because of less quench-out, so there would be fewer unburned hydrocarbons (HC) and carbon monoxide (CO) in the exhaust.
Generally, and within reason, hotter coolant is better. A hotter engine is more efficient, and there’s less engine wear and longer engine life, because there’s less unburned fuel to wash the oil down off the cylinder walls. The exhaust contains less toxic unburned fuel and carbon monoxide.

I just finished reading thru the whole allpar article...great info!!!:sSig_thanks: Does anyone here run the Evans waterless coolant? Seems like good idea.
 
If you can dissipate the heat at least as fast as it's generated, you are not overheating. It's when you fall behind that you have the problem.

And all those water replacement liquids are a scam. If your engine can't operate on 50/50 coolant, fix it so it can. The waterless stuff is a bandaid.
 
Flush the cooling system and the sediment won't build up in the radiator.
