what causes my Genesis G70 to overheat in traffic

Solution

1. Preparation

• Ensure the vehicle is parked on a level surface and the engine is cool.
• Gather necessary tools and parts.
• Disconnect the battery to prevent electrical issues.

2. Coolant Level Adjustment

• Open the coolant reservoir cap carefully to release pressure.
• If coolant is low, refill with the appropriate type of coolant (check owner’s manual for specifications).

3. Leak Repair

• If leaks are detected:
  • Replace any damaged hoses using a socket set.
  • Repair or replace the radiator if found damaged or leaking (drain coolant before removal).
  • Use a radiator sealant as a temporary fix if applicable.

4. Thermostat Replacement (if faulty)

• Remove the thermostat housing using a socket set.
• Replace the old thermostat with a new one, ensuring correct orientation.
• Reinstall the housing and torque to manufacturer specifications.

5. Radiator and Fan Inspection

• Clean any debris or blockage from the radiator fins using compressed air.
• If the cooling fan does not operate, check the fan relay and wiring. Replace as needed.
• Test the fan operation by connecting it directly to a power source.

6. Final Assembly and Coolant Refill

• Reassemble any components removed during the repair.
• Refill the cooling system with the appropriate coolant mixture.
• Bleed the cooling system to remove air pockets.
