I have a M6040 the oil pan will hold a magnet but every 2" there is a slight grove. Do you guys recommend the magnetic oil pan heater or a block coolant heater? Anybody know the size allen wrench I need to remove the plug for the coolant heater? Do you recommend draining the antifreeze or trying to just switch the plugs?
Any thoughts or suggestions appreciated, thanks
