⚠️ Safety & Precautions

• Disconnect the negative battery cable before starting. The starter cable is always hot.
• Support the truck securely on jack stands before working underneath. Never rely on a jack alone.
• Let the exhaust and starter area cool first if the engine was recently running.
• Keep the key fob away from the truck so the starter cannot energize by accident.
• Use eye protection. Rust and debris fall when you work under the engine.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Disconnect power

• Use a 10mm wrench to remove the negative battery cable from the battery.
• Move the cable aside so it cannot touch the battery post.
• Keep the key fob away from the truck.

Step 2: Raise and secure the truck

• Use a floor jack (rated 3-ton minimum) to lift the front of the truck.
• Place jack stands under the frame and lower the truck onto them.
• Make sure the truck is stable before going underneath.

Step 3: Access the starter

• From underneath, locate the starter on the lower engine block near the transmission bellhousing.
• If a splash shield or lower cover blocks access, remove it with the correct 13mm socket or 15mm socket, depending on the fasteners installed.
• Spray penetrating oil on the starter bolts if they look rusty.

Step 4: Remove the electrical connections

• Use a 13mm socket to remove the battery cable nut from the starter terminal.
• Pull the main battery cable off the starter terminal.
• Disconnect the small control wire connector from the solenoid by hand.
• Do not let the cable touch ground.

Step 5: Remove the starter motor

• Use a 15mm socket and 3/8-inch ratchet with extension to remove the two starter mounting bolts.
• Support the starter with one hand while removing the last bolt.
• Lower the starter out of the truck.
• Torque for installation later: 50 Nm (37 ft-lbs) for the starter mounting bolts.

Step 6: Install the new starter

• Position the new starter in place by hand.
• Start both mounting bolts by hand first to avoid cross-threading.
• Use a 15mm socket to tighten the starter mounting bolts.
• Torque to 50 Nm (37 ft-lbs).
• Hand-start every bolt first.

Step 7: Reconnect wiring

• Reconnect the small control wire to the solenoid.
• Reinstall the main battery cable and tighten the terminal nut with a 13mm socket.
• Torque to 12 Nm (106 in-lbs).
• Make sure the cable is seated firmly and routed away from heat and moving parts.

Step 8: Reassemble and lower

• Reinstall any splash shield or lower cover using the correct socket.
• Raise the truck slightly with the floor jack (rated 3-ton minimum), remove the jack stands, then lower the truck.
• Reconnect the negative battery cable with a 10mm wrench.
