🔧 Starter Motor - Replacement

The starter on your Sequoia sits under the upper intake area, so this job requires removing several top-side engine components to reach it. Once access is opened up, the starter itself is straightforward to unbolt and swap.

Difficulty Level: Advanced | Estimated Time: 3-5 hours

⚠️ Safety & Precautions

• Disconnect the negative battery cable before starting. The starter circuit carries high current.
• The intake area may contain fuel vapors. Work in a well-ventilated area and keep sparks away.
• Let the engine cool completely before touching the intake manifold, throttle body, or nearby hoses.
• Use care around electrical connectors and vacuum lines. Label them as you remove them.
• Assumption: access and fastener locations match the 5.7L 3UR-FE layout used on this Sequoia.

• Disconnect vacuum hoses, wiring connectors, and any attached breather lines as needed.
• Lift the manifold carefully so you do not tear the gasket surfaces.
• Replace the intake manifold gaskets during reassembly.
• Torque to 20 Nm (15 ft-lbs) on installation.

Step 4: Locate and disconnect the starter

• Find the starter mounted low in the engine valley area.
• Use a 10mm socket to remove the starter electrical terminal nut and disconnect the wiring.
• Remove any harness clips or brackets that block access.
• Do not let the cable touch ground.

Step 5: Remove the starter motor
