Solution

1. Preparation

Tools Required: Socket set, screwdrivers, cooling system pressure tester, OBD-II scanner.
Ensure the engine is cool. Disconnect the battery to prevent electrical shocks.
Gather necessary replacement parts (if needed).

2. Coolant Inspection and Replacement

Sub-steps:
1. Open the coolant reservoir cap carefully, allowing any pressure to release.
2. Check the coolant level; if low, fill with the manufacturer's recommended coolant mixture.
3. If the coolant appears dirty or contaminated, drain the old coolant using a drain pan.
4. Refill with a 50/50 mix of distilled water and coolant.

3. Thermostat Replacement

Sub-steps:
1. Locate the thermostat housing, typically near the engine block.
2. Remove the bolts securing the thermostat housing using a socket wrench.
3. Carefully lift the housing and remove the old thermostat.
4. Install a new thermostat, ensuring the correct orientation.
5. Reattach the housing and tighten bolts to the manufacturer's torque specification (usually around 15-20 lb-ft).

4. Water Pump Inspection and Replacement

Sub-steps:
1. Inspect the water pump for leaks or damage.
2. If replacement is necessary, drain the coolant again.
3. Remove the serpentine belt by loosening the tensioner.
4. Unbolt the water pump from the engine block.
5. Clean the mounting surface before installing the new water pump.
6. Install the new pump and torque bolts to the manufacturer's specification.

5. Radiator and Fan Check

Sub-steps:
1. Inspect the radiator for debris or blockages; clean if necessary.
2. Test the radiator fan by connecting it directly to a power source to ensure it operates.
3. If the fan does not work, replace the fan motor or relay as needed.
