Where is the block heater cord on a Ford F350?

The block heater cord is usually mounted on the front passenger side of the vehicle, near the bumper, at a weatherproof 120-volt outlet.

In practice, the exact spot can vary by model year and engine. Many diesel Power Stroke engines route the outlet to the front bumper or grille area, sometimes behind a protective cap. Some configurations tuck the cord into the engine bay or near the firewall. If you can't find a receptacle, your truck may not be equipped with a factory block heater, or it might be in a different location due to trim or regional specification. Always consult the owner's manual or your Ford dealer for model-specific guidance.

Common locations to check on Ford F-350

Use these typical spots as starting points when you’re hunting for the block heater outlet. Look for a weatherproof, 120-volt receptacle with a protective cap or door.

• Front bumper area, passenger side: A mounted weatherproof 120V outlet is commonly located here, sometimes behind a bumper cover or near the tow hook.


• Grille/radiator support vicinity: Some trucks route the cord along the front core support to a location near the grille for easy access in cold weather.


• Engine bay near the firewall: In certain configurations, the outlet terminates inside the engine compartment with a short extension to a visible receptacle.


• Inner fender or wheel well area (passenger side): If access from the bumper is restricted, the outlet may be tucked behind splash shields along the passenger-side front wheel area.

If you still can't locate a block heater outlet after checking these areas, your F-350 may not have a factory-installed block heater, or the cord might be placed in a region specific to your model year or regional build. Contact a Ford dealer or service technician for confirmation.

Summary

Block heater cords on Ford F-350s are typically found on the front passenger side near the bumper, with variations by year and engine. Start at the bumper, then check the grille core support, engine bay firewall area, and the passenger-side inner fender. When in doubt, consult the owner's manual or a Ford service professional to verify your exact configuration.

Do 6.7 powerstrokes have a block heater?

Yes, the 6.7L Powerstroke can be equipped with a block heater, but it was not standard on all models and may be an optional feature or a factory-installed option. To check if your truck has one, look for a silver-wrapped cord running from the engine block toward the front bumper, typically located on the passenger side. If your truck doesn't have the factory-installed heater, you can have a block heater element and cord added as an aftermarket part. 
How to check if your truck has a block heater

• Look for the cord: On the passenger side of the engine, check along the frame rail for a silver-wrapped cord. It runs from the back of the engine toward the front bumper. 
• Check for the plug: If you find the cord, there should be a plug near the front of the truck. If there is no cord, there might be a solid plug in the block with an Allen head, usually located above the starter. 
• Consult your window sticker: The most definitive way to know is to check the original window sticker for your vehicle; it will list the block heater as an option if it was installed from the factory.

• You can install one: If you don't have the factory option, you can have a block heater element and cord installed as an aftermarket part. 
• Where to find parts: You can purchase a block heater element and cord kit for a 6.7L Powerstroke from a Ford dealer or a third-party supplier. 

Where is the block heater located?

The block heater cord is typically located near the front grille or along the sides of the engine bay, sometimes hidden behind a small tab or a piece of brightly colored tape. For vehicles without an external cord, the heater is installed directly into the engine block, often as a plug-in element on the side, or an oil pan heater. The exact location can vary significantly by vehicle model, so check your owner's manual for the specific placement in your car.
