It's just a matter of flow. In the poor position the oil cooler drains at rest and the oil has to be pushed through it. In the good position the cooler remains full and is being pushed out of the cooler by the natural flow of oil into it. In the best position, gravity produces the natural flow through the cooler and no additional pushing or pulling needs to be done to compensate for the additional path that the oil has to travel through.

Hmmm, would that even matter? the oil is being pumped to the same height in the end. Perhaps you would get better flow through it if the outlet was at the top and the inlet at the bottom due to convection in the oil? Edit: I take convection idea back, after thinking about it a bit more... it doesnt actually make any sense and wouldnt work that way lol Last edited by ValidusVentus; 11-26-2013 at 05:51 PM. |

I think to your point earlier, it's only critical for start up. Once running and the oil system is pressurized, You can turn it any direction you like, its going to flow. But those few crucial seconds during crank and startup to pressure buildup, is where the preference of orientation comes into play. Not saying any one way is wrong, just the preferred method is to let gravity maximize the flow while the pump isn't (during startup).

yeah I was thinking backwards ... but I think you were also thinking backwards when you typed that?? The outlet would be for the "cooler coolant" yes? and hence, at the bottom. |
