I live in canada and work up north where i cant plug my truck in in -40 weather. Has anybody installed a Webasto or any type of coolant heater in one of these trucks yet? And does anybody know if that would void my warranty?

 

the only ting i can say go for it its good for enviroment engine fuel consumption etc i put mine under the truck inside frame rail in a small custom made stainles steel box since there is so limited with space in the engine compartment i am working with this stuff some times and have installed a couple for my customers look at e bay germany for price i use to buy from there its better price any way then in sweden but they are plenty of them here in the junkyards for 30 % of new price most cars have webasto or eberspächer here in sweden
my old truck is a 2005 f250 diesel and it is euquipped with one and my new is allso a f250 diesel from 2012 i have the remote controll to its so nice to be in the citchen and drinking coffe and just press a button and there it goes on
regards from peter

 

I would just ask Ford.
