The engine block fuses for a 1999 Ford F-250 are located in the fuse box in the engine compartment. The fuse box is located on the driver's side of the engine compartment, near the battery.
To access the fuse box, you will need to open the hood of your truck and remove the cover of the fuse box. The cover is held in place by two screws.
Once the cover is removed, you will see the engine block fuses. The engine block fuses are located in the top row of the fuse box. They are labeled "E/B" or "EBP."
The engine block fuses are responsible for protecting the electrical circuits that power the engine block heater and the glow plug system. If one of these fuses blows, the engine block heater or the glow plug system will not work.
If you need to replace an engine block fuse, be sure to use a fuse of the same amperage. Using a fuse of a higher amperage than specified could cause damage to the electrical circuits.
