-25 no block heater = Bad News

[Rudolph]

Hey Guys I had my truck plugged in all night and went to start in the morning and it was extremely difficult and once it was running it was very rough and smoking a lot. I checked my engine block and the the block heater wire and they were ice cold so obviousely not working. Is the block heater replacable? Is it a hassle or easy to access? Where abouts is it?

Thanks
much app.

99% of the time its not the block heater that failed, its the plug. Go buy a 3 prong plug from you local hardware store, cut that factory end off, splice the new one in, and you're good to go. A way to check if it's the plug is to ohm out the two flat prongs on the factory plug. We ohmed mine and it should read either infinate or 1.0 (normally whatever they read in air, as in an open circuit), when we replace the plug it was 0.01 or 0.001. either way, it was different lol

+1 on that for sure. Happens all the time to our trucks. Either salt gets in the male plug, or it had rubbed somewhere and shorted.

I have a block heater cord for sale actually PM me. It is brand new OEM from ford I just never used it.

I am sure you made sure that the breaker to the outlet didnt pop, or the extension cord you used isnt bad?

But yeah, most of the time it is just the plug...easy fix.
