Can't find any info about coolant drains on the 3.5L engine block. Thought I'd post to this thread to see if anyone has looked and knows if a drain exists. Just about to change coolant on my 2015 V6. If there are no replies I'll post back here what I find on my Edge when I get under it.
I finished up my 5L F150 and was surprised to discover ... no engine block drain. I don't understand why. Can't be that much cheaper to eliminate the block drain.
