Solution

1. Preparation

Tools Required: Socket set, screwdrivers, coolant pressure tester, OBD-II scanner.
Allow the engine to cool completely before proceeding.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Replace Coolant

Sub-steps:
1. Remove the coolant reservoir cap and check the coolant level.
2. If low, top off with the appropriate coolant type (refer to owner's manual for specifications).
3. If the coolant is dirty or contaminated, drain the old coolant from the radiator and replace it with new coolant.

3. Check and Replace Radiator Fan

Sub-steps:
1. Start the engine and let it idle to operating temperature.
2. Observe if the radiator fan engages when the engine reaches normal operating temperature.
3. If the fan does not operate, check the fuse and relay associated with the fan.
4. Replace the fan motor if necessary. Disconnect the electrical connector and remove mounting bolts to replace the fan.

4. Thermostat Inspection and Replacement

Sub-steps:
1. Locate the thermostat housing (usually at the engine block or near the radiator hose).
2. Remove the thermostat housing by unscrewing the bolts.
3. Remove the old thermostat and inspect for proper opening/closing.
4. Install a new thermostat with the correct orientation and torque the housing bolts to the manufacturer’s specification.

5. Water Pump Inspection and Replacement

Sub-steps:
1. Inspect the water pump for leaks or unusual noise.
2. If necessary, remove the drive belt and unbolt the water pump from the engine block.
3. Install the new water pump, ensuring a proper seal with the gasket, and torque bolts to specifications.
