Where is the engine block heater cord located from factory on a 2008 super duty?

On a 2008 Ford Super Duty, the factory engine block heater cord is typically located on the passenger side of the engine block, near the bottom. It's often tucked up somewhat near the frame rail and might be difficult to see without getting down low and looking carefully. It usually has a rubber grommet or boot where it passes through the firewall or frame.

However, the *exact* location can vary slightly depending on the specific engine (6.0L Power Stroke, 6.4L Power Stroke, or gasoline engine) and even minor variations within the model year. It's a good idea to consult your owner's manual, as it might have a diagram showing the precise location. If you don't have the manual, you can often find a digital version online through Ford's website.
