Had to replace the oil cooler on the wifes 3.6, the down sode to the 3.6 is that everything is connected to everything else. But its all done now, it got new plugs and intake gaskets with i was that deep into it.
There is one thing I like about that engine: The location of the oil filter cartridge. Right on top, easy to reach, and no spilling oil all over the dang place when switching it out.
