I understand that the Tru-cool LPD coolers have a cold weather passive bypass already built in (https://trucool.com/products) just wondering at that point if the Derale Fluid control thermostat really adds any benefit? Spoke to a supplier and he mentioned that people like those coolers because it saves them the cost/time of having to setup a bypass. If there is a benefit I still think I will get one (I’m in Vancouver, BC, and winter temps usually can get around 32F, lowest I’ve seen it hit here is around 14F but that’s not very often. Also thinking the 4454 is a good size for towing 3000lbs with my 2013 OB 3.6R through the mountains here, just scratching my head on that bypass.
