How to install a block heater on a John Deere 2210 compact tractor

This is a hands-on DIY install of a block heater on a John Deere 2210, replacing a freeze plug with an adapter plate and heating element. It covers removing the side panel, punching out the freeze plug, draining coolant, fitting the adapter and gasket in tight quarters, torquing it in, and refilling/bleeding coolant, with a leak check afterward. Useful for owners tackling this specific freeze-plug-style install themselves, since the creator notes no similar tutorial existed.
