I'm going to install an EA81T oil cooler on my brat soon.. I have a question about oil changes.. will there be dirty oil stuck in the oil cooler's radiator or, since they open and close thermostatically (right?), does it sit high enough that it all drains out through the filter adapter into the pan when you shut the car off? thanks

There will still be SOME old oil left in it...as wil there still be old oil trapped in the bearings and oil galleys when you are doing your oil change...the ammount should not be enough to worry about as long as you use Mobil 1 or AMSOIL synthetic or Catrol dino oil....
