Cooling

I run a 180 T stat. I run 180-185 when moving, in traffic 190-195 and then drops back down once i start moving.

Anyone who runs a 160 stat is not doing their engine any good, that stat will never close, it just stays open and becomes a restriction to flow.

What do you think your 180 stat is doing when you're at 185-195? Same thing a 160 is doing above that temp.

The thermostat does 2 things. It allows the engine to warm up faster and provides a restriction to the flow of coolant. This is why you can run a restriction ring instead of a thermostat and MUST run one if you have an electric pump.

I'm not advocating running a 160, just want to be clear how it works. As a reference, my engine builder recommends a 180 stat in mechanical pump cars.
