Hyundai 36100-22805 Starter Assembly

To assess the health of a slow-cranking starter motor, you can: Ensure the battery is charged and connections are tight. Check for potential issues like partial engine seizure or incorrect oil viscosity. Run the engine to normal operating temperature, disconnect the coil wire, and connect a voltmeter between the positive and negative battery posts. Crank the engine and record the voltage readings when it stabilizes (do not run the starter motor for over 30 seconds). A reading of 9 volts or more at cranking speed is normal, while less than 9 volts suggests potential issues with the solenoid contacts, starter motor, discharged battery, or poor connections.

Where applicable on later models, remove the EGR valve.
