🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Disconnect the Battery

• Open the hood and locate the battery on the driver-side front area of the engine bay.
• Use a 10mm wrench to loosen the nut on the negative battery terminal.
• Lift the negative cable off the battery post and tuck it aside so it cannot touch the post.
• Use a battery terminal brush to clean the terminal if you see corrosion.
• Negative cable always comes off first.

Step 2: Remove the Air Intake Duct

• Use a flathead screwdriver to loosen the intake hose clamp.
• Use needle-nose pliers to release any small hose clamps attached to the intake duct.
• Use a 10mm socket and 3/8-inch ratchet to remove any intake duct retaining bolts or clips if equipped.
• Lift the intake duct out of the engine bay and set it aside.

Step 3: Locate the Starter

• Use a shop light to look at the top rear of the engine where it meets the transmission.
• The starter is mounted to the transmission bellhousing, which is the metal case between the engine and transmission.
• Find the large battery cable and the smaller control connector on the starter solenoid.
• The solenoid is the small round section attached to the starter that switches battery power on.

Step 4: Disconnect the Starter Wiring

• Use a 12mm socket, 3/8-inch ratchet, and 3/8-inch extension to remove the nut from the large starter cable terminal.
• Pull the large cable off the starter terminal and move it aside.
• Press the lock tab on the smaller starter connector by hand and unplug it.
• If the lock tab is stuck, use a flathead screwdriver gently to release it.
• Do not pull on the wire.

Step 5: Remove the Starter Mounting Bolts

• Hold the starter with one hand so it does not fall when the bolts are removed.
• Use a 14mm socket, 3/8-inch ratchet, and 3/8-inch extension to remove the starter mounting bolts.
• Keep the bolts organized as they come out.
• Pull the starter straight away from the transmission and lift it out of the engine bay.

Step 6: Compare the New Starter

• Set the old starter and new starter next to each other.
• Use a shop light to compare the mounting holes, gear nose, and electrical terminals.
• Make sure the new starter matches before installing it.
• Use a clean rag by hand to wipe the starter mounting surface if dirty.

Step 7: Install the New Starter

• Position the new starter against the transmission bellhousing by hand.
• Start both mounting bolts by hand first to prevent cross-threading.
• Use a 14mm socket, 3/8-inch ratchet, and 3/8-inch extension to snug both bolts.
• Use a torque wrench 10-80 ft-lb range and 14mm socket to tighten the starter mounting bolts to Torque to 50 Nm (37 ft-lbs).
• Start bolts by hand first.

Step 8: Reconnect the Starter Wiring

• Apply a tiny amount of dielectric grease to the seal area of the small connector.
• Push the small starter connector in until it clicks.
• Place the large battery cable onto the starter terminal.
• Use a 12mm socket and torque wrench 10-80 ft-lb range to tighten the starter cable nut to Torque to 10 Nm (7 ft-lbs).
• Make sure the rubber protective boot covers the large starter terminal completely.

Step 9: Reinstall the Air Intake Duct

• Set the intake duct back in place by hand.
• Use a 10mm socket and 3/8-inch ratchet to reinstall any intake duct bolts.
• Use a flathead screwdriver to tighten the intake hose clamp until snug.
• Use needle-nose pliers to reinstall any small hose clamps.
• Check that the intake duct is fully seated and all hoses are connected.

Step 10: Reconnect the Battery

• Place the negative battery cable back onto the negative battery post.
• Use a 10mm wrench to tighten the terminal nut until snug.
• Apply battery terminal protectant after tightening.
• Do not overtighten the battery terminal because it can crack.
