Solution

1. Preparation

Tools Required: Socket set, coolant pressure tester, OBD-II scanner, multimeter
Ensure the engine is cool before starting work to avoid burns.
Disconnect the battery to avoid electrical issues while working on components.

2. Check and Replace Coolant

Sub-steps:
1. Remove the radiator cap carefully.
2. Inspect coolant for contamination or color change (should be bright, not rusty or muddy).
3. If coolant is low, top it up with the manufacturer's recommended coolant.
4. If coolant is contaminated, fully drain the system and replace with fresh coolant.

3. Inspect and Repair Cooling System Components

Sub-steps:
1. Check all hoses for signs of wear, leaks, or cracks. Replace any damaged hoses.
2. Inspect the water pump for leaks or unusual noises; replace if necessary.
3. Examine the radiator for blockages or damage; clean or replace as needed.
4. Test the radiator fan with a multimeter to ensure it operates properly. Replace the fan if it does not engage.

4. Flush the Cooling System

Sub-steps:
1. Use a coolant pressure tester to check for system integrity. Repair any leaks found.
2. Perform a coolant flush to remove debris and buildup. Follow the manufacturer's instructions for flushing the system.
3. Refill the cooling system with the appropriate mixture of coolant and distilled water.

5. Reassemble and Test

Sub-steps:
1. Reattach any components removed for access.
2. Reconnect the battery.
3. Start the engine and allow it to reach operating temperature while monitoring the temperature gauge.
4. Check for any leaks or unusual noises.
