Hey guys...need to replace the old tank style block heater on my skidsteer (photo provided). Want to replace it with a lower radiator hose style or better yet a freeze plug style heater. Anyone here ever have any luck installing the freeze plug style onto the Kubota D1402 diesel engine? I'm a little timid to try it...heard it could be difficult on some engines. Any experienced advice is much appreciated! Thanks, Dan.
