IMO the Katz lower radiator hose is the only way to go. Some of the nay sayers think the coolant must be circulated for it to work. I plug mine in about an hour before starting at -20F. Touch hand on head and it feels warm. Tractor starts right up like 40F. A little tight fit installing but well worth it. I tried a magnetic one on the pan and really not a good place on the N to put and did not seem to heat much at all. So try to take it off while it is hot. Forget it! Again my opinion and experience.
