why is my Skoda Octavia's engine overheating during traffic

Solution

1. Preparation

• Tools Required: Screwdriver set, coolant, funnel, pressure tester, OBD-II scanner, multimeter.
• Allow the engine to cool before starting work to avoid burns.

2. Check and Refill Coolant

• Sub-steps:
  1. Open the hood and locate the coolant reservoir.
  2. If coolant is below the minimum level, add the appropriate type (usually a 50/50 mix of water and antifreeze).
  3. Start the engine and let it run until it reaches operating temperature, checking for leaks.

3. Inspect Cooling Components

• Sub-steps:
  1. Inspect the radiator for any visible damage or blockages (e.g., dirt, debris).
  2. Check the radiator hoses for cracks or leaks; replace if necessary.
  3. Ensure the cooling fan is properly connected and operational by testing it with a multimeter (should activate when temperature rises).

4. Pressure Test the Cooling System

• Sub-steps:
  1. Attach a pressure tester to the radiator cap.
  2. Pump the tester to check for leaks; observe if the gauge holds pressure.
  3. If pressure drops, inspect all components of the cooling system for leaks and repair or replace as needed.

5. Flush and Replace Coolant (if necessary)

• Sub-steps:
  1. Drain the existing coolant by opening the radiator drain plug.
  2. Flush the system with water until it runs clear.
  3. Refill with fresh coolant, ensuring the system is bled of air pockets.
