I undestand how thermostats are intended to bring the engine up to temp quicker, but I am confused by people who say they don’t slow coolant flow. How can they not? The opening in a thermostat is quit small compared to an open hose. I am just wondering if coolant is moving to fast through my system and not having enough time to cool down in the radiator. Yes the ‘29 radiator is smaller than the ‘35-‘36 radiator. Has anybody installed thermostats that cured an engine from getting to hot? It did not move past 210 but I was not sitting and idling a lot. I have a ‘46 Ford mechanical fan up front.
