Can someone help me understand the operation of the Thermostatic Oil Cooler Bypass Valve, commonly referred to as a Vernatherm? Specifically, when the engine oil is cold and the valve is open, is all oil forced to bypass the cooler or does only a portion of it bypass with some still going through the oil cooler? Is the valve more like a T fitting? When cold, incoming oil is split between bypassing the oil cooler with some still going through it?
It is my understanding that when the oil is hot and the valve closes, it forces all oil through the oil cooler.
What I don't quite understand is why winterization plates or blocking off part of the oil cooler helps keep oil temperatures up if the oil isn't really flowing through the oil cooler anyway.
