Over heating on deuce

[JasonS]

OK can you run an engine without a thermostat....yes. Will it overheat? Probably not. But, 2 things most of you are not taking into consideration.

One is the MF has 3 different paths the coolant can flow and the thermostat dictates where that coolant goes.

Two is diesels are NOT gas engines. They DON'T always run better just because they are cooler. They have a happy temperature range they run most efficiently at.

Again can and should are 2 different things.

I don't think anyone suggested that the multi should be operated without a thermostat; only that the idea that water can move too fast to cool is false.
