Re: Freeze Plug
The block heater "element is housed in brass and sealed with an O-ring and takes up the entire space of the freeze plug opening by itself. One screw goes through the center of it from the outside and holds the unit in with what could best be described as a drywall style toggle bolt arrangement.
Unfortunately for you and Jim I don't know my Fords as well as my Mopars yet and I don't know the freezeplug opening size or the O-ring size yet. If you hop on down to Canadian Tire and buy a block heater for your application you can do the following.
Open it up and look at it. This will explain how it goes together, and yes you can change the actual cord without pulling the element. Take the O-ring off carefully and walk in to a real automotive jobber and buy another just like it. It'll probably be the same size as your original or close enough. If no jobber in town has an O-ring, go to a plumbing supplier or hardware store, anywhere that sells pitless adapters,etc, they'll have em'.
Take it all home, drain the coolant, pull the old block heater, clean it and the hole up real good and install the new O-ring. If you wreck the element taking it out or the O-ring doesn't do the trick, use the new block heater. If things go well, walk back into CTC and hand back the new block heater and get your money back.
If it gets down to -40 I'd pop for the Stant 205 degreeT-stat from a jobber as CTC doesn't carry Stant.
I've never felt the motor at night when it's plugged in, but it's warm enough the truck starts faster and the choke doesn't stay on as long(if my EFI has a choke). It's meant for Canadians and people from Northern Minnesota,etc, where it's truly cold. Truth be told I didn't use mine once last Winter.
As for the 205 degree T-stat, it's a heat factory !!!!!!!!!!
