Re: Genset Coolant Drain Question
Reply #3 –
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.
