🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Raise and support the front of the Tucson

• Use a floor jack (rated 3-ton minimum) to lift the front at the proper lift point.
• Set the vehicle down onto jack stands (rated 3-ton minimum).
• Give the vehicle a firm shake to confirm it’s stable.

Step 2: Remove the lower splash shield (undercover)

• Use a trim clip remover and flathead screwdriver to remove plastic clips.
• Use a 10mm socket (common) to remove any small bolts, then lower the shield.

Step 3: Locate the starter

• Use a flashlight to find the starter on the transmission bellhousing (where the engine and transmission meet).
• You’ll see a thick battery cable on a stud and a smaller control wire (signal wire).

Step 4: Remove the starter electrical connections

• Remove the rubber boot from the main terminal by hand.
• Use a 12mm socket (varies by replacement starter) to remove the main battery cable nut, then pull the cable off the stud.
• Use a 10mm socket or release tab by hand (varies) to disconnect the small signal wire connector.
• Tip: Tie cables up so they don’t snag.

Step 5: Remove the starter mounting bolts

• Support the starter body with one hand.
• Use a 14mm socket with a 3/8" drive extension set and universal joint adapter (3/8") to remove the starter mounting bolts.
• Carefully slide the starter out of the bellhousing and down/out.

Step 6: Install the new starter

• Compare the new and old starter (mounting ears, electrical studs, and connector location) before installing.
• Position the starter into the bellhousing opening by hand.
• Start all mounting bolts by hand first to prevent cross-threading.
• Tighten the bolts with a 14mm socket, then finish with a torque wrench (10–150 ft-lbs).
• Torque to OEM specification for starter mounting bolts.

Step 7: Reconnect the starter wiring

• Install the small signal wire connector by hand until it clicks (or tighten its small fastener with a 10mm socket, if equipped).
• Install the main battery cable onto the starter stud and tighten the nut with a 12mm socket, then finish with a torque wrench (10–150 ft-lbs).
• Torque to OEM specification for starter B+ terminal nut.
• Reinstall the rubber boot over the main terminal.

Step 8: Reinstall the lower splash shield

• Raise the shield into place.
• Reinstall bolts with a 10mm socket and clips with a trim clip remover.

Step 9: Reconnect the battery and lower the vehicle

• Reconnect the negative (-) terminal using a 10mm socket, then tighten with a torque wrench (10–150 ft-lbs).
• Torque to OEM specification for battery terminal clamp.
• Use the floor jack (rated 3-ton minimum) to lift slightly, remove jack stands (rated 3-ton minimum), then lower fully.

Quick check so I can give you the exact torque specs:

• Do you want the OEM torque specs if I list the two most common Hyundai values for this platform (and you confirm which matches your bolts), or do you have access to your under-hood service label/manual torque table?
