my Genesis G70 won’t start in cold weather what should I do

Solution

1. Preparation

• Gather tools: multimeter, socket set, jump starter or battery charger.
• Ensure the vehicle is in a safe and level location, and the parking brake is engaged.

2. Battery Inspection and Replacement

• Check Battery Condition
  • Inspect for physical damage or leaks.
  • Clean the terminals with a wire brush and a mixture of baking soda and water if corrosion is present.
• Test Battery Voltage
  • Use a multimeter to check if the voltage is below 12.4V. If so, charge the battery or replace it if it cannot hold a charge.
• Replace the Battery (if necessary)
  • Disconnect the negative terminal first, then the positive terminal.
  • Remove the battery hold-down bracket and lift the battery out.
  • Place the new battery in the tray, secure it with the hold-down bracket, and connect the positive terminal first, followed by the negative terminal.

3. Starter Motor Inspection

• Testing the Starter
  • Locate the starter motor and check connections for dirt or corrosion.
  • Use jumper cables to bypass the ignition circuit directly to the starter to see if it engages. If it does, the ignition switch may be faulty.
• Replace Starter Motor (if faulty)
  • Remove the battery as described above.
  • Disconnect the wiring harness from the starter.
  • Remove the mounting bolts securing the starter and carefully take it out.
  • Install the new starter by reversing the removal steps.

4. Fuel System Check

• Fuel Pressure Test
  • Connect a fuel pressure gauge to the Schrader valve on the fuel rail.
  • Turn the ignition to the "ON" position (without starting) and check for adequate pressure.
  • If pressure is low, consider replacing the fuel pump.

5. Oil Viscosity Check

• Engine Oil Inspection
  • Check the oil level using the dipstick and assess its viscosity. If it appears too thick for cold weather, consider an oil change to a lower viscosity oil suitable for winter conditions.
