I want to install a block heater im my Kubota but can't find any instructions as to where to install it. I have read some posts about removing a heater hose and installing it there. It is the one with the treaded connection Kats #11409 I purchased. Dose anyone have installtion instructions as to the exact location or a picture of where it goes. I have looked at the engine but can't find any threaded plug to install it into.
