Solution

1. Preparation

Gather Tools: OBD-II scanner, coolant pressure tester, socket set, torque wrench, and safety gloves.
Safety Warning: Allow the engine to cool completely before working on the cooling system to avoid burns.

2. Address Coolant Level

Sub-step 1: If coolant is low, top it up with the manufacturer-recommended coolant type.
Sub-step 2: If coolant is not circulating, consider replacing the thermostat.

3. Repair Leaks

Sub-step 1: Locate any leaks found during inspection.
Sub-step 2: Replace any damaged hoses or components and ensure all clamps are secure.

4. Replace Thermostat (if faulty)

Sub-step 1: Drain coolant from the radiator.
Sub-step 2: Remove the thermostat housing using a socket set.
Sub-step 3: Replace the old thermostat with a new one, ensuring correct orientation.
Sub-step 4: Reassemble and refill the cooling system with coolant.

5. Repair or Replace Water Pump (if necessary)

Sub-step 1: If the water pump is identified as faulty, drain the coolant.
Sub-step 2: Remove any components obstructing access to the water pump (e.g., belts, hoses).
Sub-step 3: Replace the water pump, ensuring proper alignment and torque specifications.
Sub-step 4: Refill the cooling system and bleed air from the system.

6. Check Radiator Fan Operation

Sub-step 1: Test the fan by connecting it directly to battery power to ensure it operates correctly.
Sub-step 2: If the fan does not operate, replace the fan motor.
