🔧 1500 - Starter Motor Replacement

Replacing the starter motor on your 1500 means removing the failed starter from the lower passenger side of the 5.7L HEMI engine and installing a new one. The starter uses high-current battery power, so careful battery disconnection is required before touching any starter wiring.

Difficulty Level: Intermediate | Estimated Time: 1.5-2.5 hours

⚠️ Safety & Precautions

• ⚠️ Disconnect the negative battery cable before starting. The starter cable is always hot when the battery is connected.
• ⚠️ Let the exhaust cool fully before working underneath. The starter sits near hot exhaust components.
• ⚠️ Support your 1500 with jack stands if you raise it. Never work under a truck supported only by a jack.
• ⚠️ Keep the key fob away from the truck while working to prevent accidental wake-up or remote start activity.
• ⚠️ If equipped with air suspension, disable automatic leveling from the Uconnect settings before lifting.

📋 Before You Begin

• Park your 1500 on level ground, shift to Park, and set the parking brake.
• Place wheel chocks behind the rear wheels so the truck cannot roll.
• If equipped with air suspension, use the Uconnect screen and select Apps > Settings > Suspension > Tire/Jack Mode before lifting.
• Open the hood and disconnect the negative battery cable using a 10mm wrench.
• Wait at least 2 minutes after disconnecting the battery before touching starter wiring.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Raise and Support the Truck

• Use a floor jack rated 3-ton minimum to lift the front of your 1500 at a safe front frame lifting point.
• Place jack stands rated 3-ton minimum under the frame rails.
• Gently lower the truck onto the jack stands and lightly shake the truck to confirm it is stable.
• Put on safety glasses and nitrile gloves.
• Never trust the jack alone.

Step 2: Remove Any Lower Shielding Blocking Access

• Look under the passenger side of the engine for any splash shield or closeout panel blocking the starter area.
• Use a 10mm socket or trim clip removal tool to remove any fasteners or plastic clips.
• Set the shield and fasteners aside in order so they go back in the same locations.

Step 3: Locate the Starter Motor

• Use a work light to look at the lower passenger side of the engine where the engine meets the transmission.
• The starter is a small cylindrical electric motor bolted to the transmission bellhousing.
• The bellhousing is the metal housing between the engine and transmission.

Step 4: Disconnect the Starter Wiring

• Confirm the negative battery cable is disconnected before touching the starter wires.
• Use a 13mm socket to remove the nut holding the large battery cable to the starter terminal.
• Move the large cable aside so it cannot touch the starter terminal.
• Use a 10mm socket to remove the small solenoid wire nut, if equipped with a nut-style terminal.
• If your small solenoid wire uses a push connector, press the locking tab by hand and pull the connector straight off.
• The solenoid is the smaller electrical switch mounted on the starter that engages the starter gear.
• Take a phone photo first.

Step 5: Remove the Starter Mounting Bolts

• Support the starter with one hand because it is heavier than it looks.
• Use a 15mm socket, ratchet 3/8-inch drive, 6-inch extension, and universal joint to remove the starter mounting bolts.
• A universal joint lets the socket bend slightly to reach bolts at an angle.
• Remove the lower bolt first, then the upper bolt.
• Carefully lower the starter out of the engine bay.

Step 6: Compare the Old and New Starter

• Place both starters side by side on a clean surface.
• Check that the mounting ears, electrical terminals, and gear nose match.
• Do not install the new starter if the case shape or terminal layout is clearly different.
• Matching shape prevents fitment problems.

Step 7: Install the New Starter

• Lift the new starter motor into position by hand.
• Start both mounting bolts by hand first to avoid cross-threading.
• Use a 15mm socket, 6-inch extension, and ratchet 3/8-inch drive to snug the bolts evenly.
• Use a torque wrench 3/8-inch drive and 15mm socket to tighten the starter mounting bolts to Torque to 54 Nm (40 ft-lbs).

Step 8: Reconnect the Starter Wiring

• Install the small solenoid wire first.
• Use a 10mm socket to tighten the small solenoid terminal nut, if equipped, to Torque to 5 Nm (44 in-lbs).
• Connect the large battery cable to the starter main terminal.
• Use a 13mm socket and torque wrench 3/8-inch drive to tighten the main cable nut to Torque to 13 Nm (115 in-lbs).
• Make sure the cable eyelets sit flat and the rubber terminal cover is fully seated.

Step 9: Reinstall Lower Shielding

• Position any removed splash shield or closeout panel back into place.
• Use a 10mm socket to reinstall the bolts.
• Use a trim clip removal tool by hand to help align any plastic clips before pushing them in.
• Tighten small shield bolts snug only unless a factory torque label is present.

Step 10: Lower the Truck and Reconnect the Battery

• Use the floor jack rated 3-ton minimum to lift the truck slightly off the jack stands.
• Remove the jack stands rated 3-ton minimum.
• Lower your 1500 fully to the ground.
• Reconnect the negative battery cable using a 10mm wrench.
• Apply battery terminal protectant to the battery terminal after it is tightened.

✅ After Repair

• Start your 1500 and listen for smooth cranking without grinding, clicking, or dragging.
• Check that the battery warning light turns off after the engine starts.
• Look underneath with a work light and confirm the starter wiring is not touching the exhaust or moving parts.
• If equipped with air suspension, turn Tire/Jack Mode off using Apps > Settings > Suspension > Tire/Jack Mode.
• The clock, radio presets, and one-touch window function may need to relearn after battery disconnection.
