Can not find the coolant drain plug on my 2009 2wd L4-2.5L (2AR-FE) engine Rav 4. I found one possible bolt about 2 inches above the oil pan close to the oil filter looking from the front. This would be in the general location of where I have seen pictures of drains, but they seem to have a little spout to attach a hose, but not sure enough to loosen it. Also found a bolt with a star head that matches nothing that I have seen in any manual. Could you give me a location for the engine drain plug and what it should look like? Thank you
