Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety while working on the electrical components.

2. Coolant System Inspection

Sub-steps:
- Remove the coolant reservoir cap and inspect coolant levels.
- If low, top up with the manufacturer-recommended coolant mixture.
- Inspect all hoses connected to the radiator and engine for any signs of wear or leaks; replace any damaged hoses.

3. Replace Thermostat (if faulty)

Sub-steps:
- Locate the thermostat housing, typically near the engine block.
- Remove the bolts securing the housing using a socket set.
- Carefully lift the housing and remove the old thermostat.
- Clean the mating surfaces and install a new thermostat with a new gasket.
- Reattach the housing and torque the bolts to the manufacturer's specifications.

4. Water Pump Replacement (if needed)

Sub-steps:
- Drain the coolant from the system into a suitable container.
- Remove the drive belt from the water pump.
- Unscrew the bolts securing the water pump to the engine block and remove the pump.
- Clean the mounting surface on the engine block.
- Install the new water pump, ensuring it is aligned properly, and torque the bolts as specified.
- Refill the coolant system with the recommended fluid.

5. Testing the Cooling Fans

Sub-steps:
- Reconnect the battery.
- Start the vehicle and allow it to reach operating temperature.
- Monitor the cooling fan operation; they should activate as the engine warms up.
