installed block heater cord

[06F-250-6.0]

now when i plug it in to the extension cord it seems kinda lose and if you wiggle it or move it just a little it sparks blue and sizzles and pops...its not full out sparks its hard to explain...i got the cord from the dealership and it didnt have a lock ring or anything just some gold ring thing on the end that plugs into the block...is that suposed to tighten down somehow because i can just spin it all the way around...could it be my extension cord? ill try a new one when i get back from michigan...thanks in advance....

Could be the extension cord. Is it a heavy duty cord?

mine came with what looked like a nut,I plugged the cord into the block then tightened it, It didn't turn a lot but it did snug down. I use a heavy duty extension cord, and its a tight fit from the block heater cord the my extension cord.

Ditto on mine. I read somewhere that not all years use the locknut. Based on the quote above and that I used the locknut on mine I'd say 2005's do.

Hey Guys. I just finished installing the Ford dealer purchased cord on my 06 F-250. The heater which is already in the block has 2 prongs set into it surounded by a threaded boss. I have seen 2 types of cord - one which has a chrome colored retaining ring that matches the threads and gets tightened after the cord is plugged in - or the one like mine that has a gold colored ring with 2 prongs - this ring gets pushed stright on without turning. As you push the ring on - the prongs will snap on the threads until it bottoms out and the ring locks the cord end on the heater.
