My apologies if this has already been posted, but good lord what a awful time I had this morning simply draining the coolant from the radiator of my 2016 Pilot. I had to remove two separate pieces of protective trim under the radiator to even find the drain valve in the first place. You can't even see it from underneath by looking thru the exisitng holes in the trim. It's all gotta come off. Forget what you see in the YouTube videos. If you have a Pilot like mine, there is no access panel or open area under the drain. It is hidden above the under-engine trim. In fact, had I not attached a drain hose to the valve, coolant would have spilled all over the remaining trim before finding a way to the ground or my pan. Since I just only did a drain and refill without opening the block coolant plug (that is even more difficult to get at), I have all this to look forward to again in a few days so I get a more complete flush-out of the old coolant.
