    Oil Cooler and Oil Return

    I see that most of the Oil Coolers people have are in a position that is much higher than the engine, so the oil must rise and then lower.

    What happens when the engine shuts down (the oil pump stops working)? All that oil goes down? There is no possibility that the oil overflows the filling cap? How do you know if the oil is level (when going down it will show more than normal)? Or the coolers have a sort of checking valve that avoid all of this happens?

    Thanks for the answers, regards

    if the fittings are on top of the cooler it wont drain the cooler down. the amount in the lines will be minuscule.

    If the oil cooler ports are facing down....does the oil pump flow enough to flush out the air sitting at the top?

    Make a lot of sense, I don't thing about that. Whit that in mind, a check valve is not needed.

    Thinking a little more, what happens to the old oil in the oil cooler at the moment of a oil change? As the old oil don't drain to the carter then remains in the cooler and mix with the fresh one. What you people do in general in the oil change? Or is not important?

    couple of oz of old oil aint gonna cause a problem. always have oil cooler ports at the top or fill at bottom drain at top so the full oil cooler is used.
