Can someone tell me where the engine block drain valve is on a Power Tech 10KW unit?
Per the manual (check the Media section of the forum), a quick look at the graphics, if it's Kubota-powered it looks like it's near the starter.
Of course it is on the back side! :facepalm:
Same problem with the smaller 8KW Isuzu, it's on the back side below the exhaust manifold outlet. Don't think about replacing the Isuzu plug with a drain cock as it is a tapered metric thread. And it must be removed if you want to get rid of the old coolant in the block, and not have to do multiple flushes (like 4 or 5 at least), and the block will be full of water. I have to remove the air cleaner and duct in order to reach it with a lot difficulty.
