3. Bleed the cooling system: If there is air trapped in the cooling system, bleed it to ensure proper coolant circulation.
4. Check the thermostat: Verify that the thermostat is working correctly and replace it if necessary.
5. Inspect the radiator fan: Ensure that the radiator fan is operating as it should. If not, have it repaired or replaced.
6. Check for coolant leaks: Inspect the water pump, radiator, and hoses for any signs of coolant leaks. Repair or replace any damaged components.
