Solution

1. Preparation

Tools Required: Socket set, screwdrivers, coolant catch pan, OBD-II scanner.
Safety Warnings: Allow the engine to cool completely before beginning work. Wear gloves and safety glasses.

2. Address Coolant Issues

Sub-steps:
1. If low, refill the coolant system with manufacturer-recommended coolant mixture.
2. Inspect for leaks; if leaks are found, replace damaged hoses or components.

3. Replace Thermostat (if faulty)

Sub-steps:
1. Drain coolant from the radiator until the level is below the thermostat.
2. Remove the thermostat housing using a socket set.
3. Replace the old thermostat with a new one and reassemble the housing, ensuring a proper seal.
4. Refill the coolant and bleed the system of air.

4. Repair or Replace Water Pump (if faulty)

Sub-steps:
1. Drain the coolant system fully.
2. Remove the serpentine belt from the water pump.
3. Unbolt the water pump from its housing and remove it.
4. Clean the mounting surface and install the new water pump, tightening bolts to the manufacturer's torque specifications.
5. Reinstall the serpentine belt and refill the coolant system.

5. Check and Repair Radiator Fan

Sub-steps:
1. Test the fan motor with a multimeter to check for continuity.
2. If faulty, disconnect the fan and replace it following the manufacturer's instructions.
3. Ensure the fan wiring is intact and connections are secure.
