2. Coolant Check and Replacement

Sub-steps:
1. Open the coolant reservoir and check the level.
2. If low, top off with the manufacturer-recommended coolant.
3. If the coolant is contaminated, drain the cooling system.
4. Refill with fresh coolant according to the manufacturer's specifications.

3. Inspect and Repair Cooling System Components

Sub-steps:
1. Visually inspect hoses for cracks or leaks; replace any damaged hoses.
2. Check the radiator for blockages; clean or replace as necessary.
3. Inspect the water pump for leaks and ensure it is functioning properly.
