š Before You Begin

- Disconnect the battery: use a 10mm socket to remove the negative (ā) terminal first, then the positive (+) if you remove the battery.
- Take a quick photo of wiring before removal.
šØ Step-by-Step Instructions
Follow these steps in order:
Step 1: Disconnect the battery
- Use a 10mm socket to loosen and remove the negative (ā) battery terminal and move it aside so it cannot spring back.
Step 2: Remove the air intake duct/air cleaner parts for access
- Use a flathead screwdriver to loosen the hose clamp(s) on the intake tube.
- Unclip/remove any intake snorkel clips with a trim clip tool.
- Lift the intake tube/air ducting out of the way (use a flashlight to spot hidden clips).
Step 3: Remove the battery (if needed for working room)
- Use a 10mm socket to remove the battery hold-down hardware.
- If you didnāt already: remove the positive (+) terminal with a 10mm socket.
- Lift the battery straight up and out. (Batteries are heavyāuse good lifting posture.)
Step 4: Locate the starter motor
- Use a flashlight to find the starter near the transmission bellhousing on the front side of the engine (itās a small motor with a thick power cable and a smaller plug).
Step 5: Disconnect the starter wiring
- Remove the small starter signal connector by pressing the tab and pulling it off (use needle-nose pliers gently if itās tight).
- Remove the rubber boot covering the thick power cableās nut.
- Use a 12mm socket to remove the nut holding the main power cable to the starter terminal.
- Do not twist the studāhold the cable steady.
Step 6: Remove the starter mounting bolts
- Use a 14mm socket, 3/8" ratchet, and a 6" or 12" extension (add a universal joint adapter if needed) to remove the starter mounting bolts.
- Support the starter with your free hand as the last bolt comes out.
Step 7: Remove the old starter and compare parts
- Wiggle the starter out carefully (it may take a little turning to clear nearby hoses/wiring).
- Compare the new starter to the old one: same mounting ears, same electrical terminals, same connector position.
Step 8: Install the new starter
- Position the new starter into place by hand.
- Thread the starter mounting bolts in by hand first (to avoid cross-threading).
- Tighten the mounting bolts with a 14mm socket and torque wrench: Torque to 44 Nm (33 ft-lbs).
Step 9: Reconnect the starter wiring
- Install the main power cable onto the starter terminal and tighten with a 12mm socket: Torque to 9 Nm (80 in-lbs).
- Reinstall the rubber boot over the terminal.
- Plug the small signal connector back in until it clicks.
- Apply a thin dab of dielectric grease inside the small connector only (optional).
Step 10: Reinstall battery and intake parts
- Reinstall the battery and hold-down using a 10mm socket.
- Reconnect battery terminals: positive (+) first, then negative (ā), using a 10mm socket.
- Tighten battery terminals securely: Torque to 5 Nm (44 in-lbs).
- Reinstall the intake ducting and tighten clamps with a flathead screwdriver.
ā After Repair
- Start the engine and listen: the starter should crank smoothly with no grinding.
- Check that no warning lights appear and that the intake tube is fully seated (no whistling/hissing).
- Recheck the battery terminals for tightness and confirm the rubber boot fully covers the starter power terminal.
- If it clicks once, recheck cable tightness.
