🔧 Forte - Starter Motor Replacement

The starter motor is the electric motor that cranks your Forte’s engine when you turn the key/push the start button. Replacing it usually means working near the battery cables and the transmission bellhousing, so careful disconnect and secure lifting are key.

Difficulty Level: Intermediate | Estimated Time: 1.5-3.0 hours


⚠️ Safety & Precautions

  • ⚠️ Disconnect the negative battery cable first to prevent a short or sparks.
  • ⚠️ Let the engine cool; you’ll work near hot components.
  • ⚠️ Support the car with jack stands; never rely on a floor jack alone.
  • ⚠️ Keep metal tools away from the starter’s main power stud; it’s direct battery power.

🔧 Required Tools

You'll need the following tools for this repair:

  • Safety glasses
  • Mechanic gloves
  • Floor jack (rated 2-ton minimum)
  • Jack stands (rated 2-ton minimum)
  • Wheel chocks
  • 1/4" drive ratchet
  • 3/8" drive ratchet
  • 3/8" drive torque wrench (10–100 Nm range)
  • 10mm socket
  • 12mm socket
  • 14mm socket
  • 6" extension
  • 12" extension
  • Flat trim tool
  • Phillips screwdriver
  • Pliers
  • Work light

🔩 Required Parts

HowToo sells all the parts you need for this repair:

  • Starter motor assembly - Qty: 1
  • Air intake hose clamp (optional) - Qty: 1
  • Battery terminal anti-corrosion washers (optional) - Qty: 1 set

📋 Before You Begin

  • Park on a level surface, shift to Park, and set the parking brake.
  • Open the hood and keep the key fob away from the car (prevents accidental wake-up).
  • Have a small container ready for bolts/nuts so nothing gets lost.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Disconnect the battery

  • Use a 10mm socket to loosen the negative (-) battery terminal and remove it from the battery post.
  • Tuck the cable aside so it can’t spring back onto the terminal.
  • Negative off first, on last.

Step 2: Remove the air intake ducting (for access)

  • Use pliers to release any breather hose clamps on the intake tube.
  • Use a Phillips screwdriver (or the appropriate clamp screw) to loosen the intake hose clamps.
  • Remove the intake tube and, if needed, the upper air box using a 10mm socket.

Step 3: Raise and support the front of the car

  • Place wheel chocks behind the rear tires.
  • Lift the front with a floor jack (rated 2-ton minimum) and set it securely on jack stands (rated 2-ton minimum).
  • Use a work light so you can clearly see the starter area.

Step 4: Remove the lower splash shield (if equipped)

  • Use a flat trim tool to pop out the plastic clips.
  • Use a 10mm socket for any small bolts holding the shield.

Step 5: Locate the starter and disconnect the wiring

  • The starter sits at the engine/transmission bellhousing area.
  • Remove the rubber boot covering the main starter power stud by hand.
  • Use a 12mm socket to remove the main battery cable nut from the starter terminal. Torque to 9.8 Nm (87 in-lbs) during reassembly.
  • Disconnect the small starter solenoid signal wire connector (pull the connector straight off). If it uses a nut style, use a 10mm socket. Torque to 4.9 Nm (43 in-lbs) during reassembly.
  • Take a quick photo before unplugging.

Step 6: Remove the starter mounting bolts

  • Support the starter with one hand while you remove bolts with a 14mm socket, 3/8" drive ratchet, and a 12" extension.
  • Remove the upper and lower starter mounting bolts.
  • Pull the starter straight out from the bellhousing.
  • During reassembly: Torque the starter mounting bolts to 49 Nm (36 ft-lbs).

Step 7: Install the new starter

  • Compare the new starter to the old one (same nose shape, same electrical studs/connectors).
  • Position the starter into the bellhousing opening and start both mounting bolts by hand to prevent cross-threading.
  • Tighten with a 14mm socket and then use a 3/8" drive torque wrench (10–100 Nm range): Torque to 49 Nm (36 ft-lbs).

Step 8: Reconnect starter wiring

  • Install the main battery cable onto the starter power stud and tighten with a 12mm socket: Torque to 9.8 Nm (87 in-lbs).
  • Reconnect the small solenoid wire connector (make sure it clicks/locks). If it uses a nut, tighten with a 10mm socket: Torque to 4.9 Nm (43 in-lbs).
  • Reinstall the rubber boot over the main power stud.

Step 9: Reinstall splash shield and intake parts

  • Reinstall the splash shield using the 10mm socket and flat trim tool for clips.
  • Reinstall the intake tube/air box using a 10mm socket, Phillips screwdriver, and pliers for clamps.

Step 10: Lower the car and reconnect the battery

  • Raise slightly with the floor jack, remove the jack stands, then lower the car.
  • Reconnect the negative (-) battery terminal using a 10mm socket.

✅ After Repair

  • Start the engine and listen: it should crank strongly with no grinding.
  • Check that no warning lights appear and that all intake hoses are fully seated (no hissing/rough idle).
  • Do a quick visual re-check for any loose wiring near the starter.
