Anyone know anout these block heaters? Do they work like in those below zero for weeks weather? I am looking at a couple on ebay for a JD 530. One says it installs in the bottom of the head on any two cylinder JD with a 3/4" pipe thread drain plug. It says it is a 400 watt, 120 volt engine block frost plug DIESEL heater. Replaces part #AR87167.
The other one says the same in terms of wattage, volts, thread size. But says "cylinder block coolant heater," for same application, but for about $20 less.
Any advice? I guess I'm going to have to drain the oil to install? Can I keep the plug itself installed on the tractor during the warm season (without plugging it in)?
Thanks,
Robert
