As stated earlier the 2008 is 2.4L, the 2009 and forward are 2.5L and are not the same engine.i already talk to that guy on the youtube video. He said he has no access to a 2009 model so he can't check. Correct me if i'm wrong but i think 2008 and 2009 or other 3.4 version has the same engine but different outline. I talk to our family friend mechanic who teaches me doing maintenance, he said that the drain plug for the engine block is probably at the back side of the engine but not an advisable to use it to drain the engine block as the coolant might corrode the switch bolt and make more damage but rather use the lower hose coming from the engine to the radiator. Same concept but lesser damage if something went wrong.
