The plug on my 6.4 L engine block heater just about melted last week when it was in the 20's and one of the prongs is loose. Now its going to be in the -teens ( yes that is negative teens ) and I dont think I can use the block heater... should I risk it or just not use my truck till I can get it fixed... ( do have some anti-gell in the tank )

 

I think wouldn't risk it, I would get to Ford and get a new on and install it right away. It doesn't look that hard to put in.

 

The only time I plug mine in is when its single digits or below and I dont even have a fuel heater anymore But yes we have two diff trucks but dont use it and the truck will be fine without it to use until you can fix it.

 

well only issue that happened with this, the darn BATTERIES died... that darned cold.
