I was just wondering how effective this system is . On my engine, Toyota calls it an oil cooler, though it is not how we think of oil coolers.
Its a donut shaped metal piece that goes right behind the oil filter, with coolant lines running through.
I heard this system is meant to equalize or bring close the coolant temps and oil temps.
Seeing that the oil that passes through the oil filter is going through this donut, and the coolant flowing around it, how effective is this system as an oil cooler compared to a finned radiator type oil cooler ?
