The Deuce works better than I ever imagined! I threw a couple of moving blankets on top, positioned the hoses into the cowls, careful not to obstruct the oil cooler, and left it plugged in to cycle on and off as needed. After a couple of days I noticed the heater only comes on maybe once every 5 minutes, and stays on no more than a minute at a time, maybe less. The engine is toasty warm. Thanks for such a great product.
