What's that cable on the F250?

[KIETHSTONE]

I have always wondered if they also help to maintain the batteries.

Yours has one. You ain’t looked very hard for the plug.

Every diesel has a block heater. I use mine when it gets in the mid 30’s or below.

Saves wear on battery, sure is nice to be toasty warm in a few minutes.

Mine does not. One can be added, but it didn’t come with one. They used to all come standard, but at some point became an option. My 7.3’s and my first 2 6.7’s had one, which is why I didn’t even think to check before buying this one.

Nope. It’s an option on 6.7s. My 2019 doesn’t have
one.

Well , I stand corrected. After talking to best friend, he has a ‘12 dodge, his block has the heater, but he had to buy the cord and plug it in, then run the cord up front.

That makes no sense to me. When motor is assembled, they have no idea what part of the country it will end up.

But, they just save $28 on a ton of trucks and kept that money in their pockets. Goes to show they don’t care about the customer.

With newer diesels, you shouldn’t ever need a block heater here in Texas. Look at the cold weather testing Ford did on the 6.7. Even in 4* temps, my ‘15 Ford 6.7 never hesitated starting.

Charges your blinkers

I'm confused... Then what's the blinker fluid for?

Lubricates the muffler bearings.

Makes perfect sense to go ahead and install it in the block at the factory. It’s a PITA to get to just to put the cord on much less if you had to try and remove a rusty plug and screw it in later.

I have my first diesel now. Bought a 6.0 f250 for a ranch truck. It’s been great for the last year. I was worried during the freeze because I didn’t plug it in but it fired up immediately. It was 20 for several days before hand. I can’t see ya needing them in Texas at all on anything modern.

Flux capacitor hook up

Guess this is your first diesel.

Before I opened the thread, I was thinking it was something they were installing so a Chevy could tow you to the mechanic.

You didn’t know that diesel trucks are plug in hybrids? Don’t feel bad. The lefties don’t know either.
