Safety First:
* Disconnect the negative battery cable FIRST. This prevents accidental shorts and shocks.
* Wear safety glasses. Metal shards and other debris can fly during the process.
* Use jack stands. Never work under a vehicle supported only by a jack.
* Have the right tools. Improper tools can lead to damage or injury.
Tools You'll Likely Need:
* Socket wrench set (metric)
* Ratchet
* Extensions
* Torque wrench
* Pry bar or similar tool (for stubborn connections)
* Wire brush (to clean battery terminals and starter connections)
* Penetrating oil (like PB Blaster)
* New starter motor (ensure it's the correct one for your year and model)
* Jack and jack stands
* Gloves
Steps:
1. Prepare the Truck: Park on a level surface, engage the parking brake, and chock the wheels. Disconnect the negative battery cable.
2. Access the Starter: The starter's location varies depending on the year and engine type. Generally, it's on the passenger side of the engine block, often somewhat hidden. You may need to remove some components to access it fully – this could include:
* Intake components: Air filter housing, etc.
* Exhaust components: Possibly some heat shields.
* Wiring harnesses: Carefully unplug and secure harnesses out of the way.
* Other components: Depending on your truck, there might be other parts that need to be moved or removed to gain access. Refer to your repair manual for exact locations and removal procedures.
3. Disconnect the Starter:
* Battery Cable: Disconnect the large battery cable(s) from the starter.
* Starter Solenoid Wire(s): Disconnect any smaller wires connected to the starter solenoid. Take pictures or make notes of their locations before disconnecting to ensure correct reassembly.
* Apply Penetrating Oil: Spray penetrating oil on any bolts that appear rusty or stuck. Let it sit for a few minutes.
4. Remove the Starter: Use the appropriate sockets and wrenches to remove the starter mounting bolts. These bolts can be very tight. A breaker bar might be necessary. The starter is usually held in place by 2 or more bolts. Once loosened, carefully remove the starter from its position.
5. Install the New Starter:
* Clean Mounting Surfaces: Clean any dirt, grime, or corrosion from the starter mounting points on the engine block.
* Install the New Starter: Carefully align the new starter and install the mounting bolts. Do NOT overtighten. Use your torque wrench and consult your repair manual for the correct torque specifications.
* Reconnect the Wires: Reconnect the battery cable(s) and solenoid wires in their original positions, ensuring secure connections.
6. Reassemble: Reinstall any components removed to access the starter in the reverse order of removal.
7. Reconnect the Battery: Reconnect the negative battery cable.
8. Test the Starter: Try starting the engine. If it doesn't start, double-check all connections and ensure everything is properly secured.
Important Considerations:
* Power Steering Pump: On some models, the power steering pump may need to be loosened or removed to access the starter.
* Exhaust Manifold: Be aware of the heat from the exhaust manifold; allow ample cooling time before working in that area.
* Professional Help: If you're not comfortable performing this repair yourself, take your vehicle to a qualified mechanic. This is a moderately complex repair that requires mechanical aptitude and the right tools.
This guide provides a general overview. Always refer to a repair manual specific to your year, make, and model of Ford F-350 for detailed instructions and diagrams. Incorrect installation can lead to damage or injury.
