it's currently -30 degrees out, brother in-laws who owns the machine is out of town and cannot find the plug to prewarm the engine,
On the 312c it has a 3064T cat engine that doesn't use a block heater. It uses a circulation heater which is usually installed either on a heater hose, or on the lower radiator hose. Check the hoses to see if there is a cylinder or a box with a plug on it. If it doesn't have one, they are available at most equipment or automotive stores. You would have to know the inside diameter of the hose when you go to purchase a lower rad hose model. If it's going in a heater hose, they are a standard 5/8. Hope this helps you. Keep warm! Rob
