Water Jacket Plug??

[bill18163]

Take a look at the attachment to this thread. This is the engine block of my B2710HSD. In particular notice part 50 which is a plug. Right below the p50 is a water drain hose that drains the water jacket of the engine(p230). Does anyone know if the p50 plug also accesses the water jacket? I am looking for a way to drain the water from the engine faster than just draining through the conventional drain cock. It would also be easier to flush cleaners out of the system if this plug is an access. If anyone
knows, please let me know. Thanks.

It appears from the drawing that p50 would also drain the water but I don't have a Kubota.
What about removing the lower radiator hose. That would drain it real quick.

Yes that p50 does open into the water jacket. I also just flushed my B2620 recently and didn't have any problems using the provided drain. These tractors don't hold much coolant.
