Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to avoid electrical mishaps.

2. Check and Refill Coolant

Locate the coolant reservoir and remove the cap.
If the coolant level is low, mix new coolant with water according to manufacturer specifications, generally a 50/50 ratio.
Fill the reservoir to the recommended level and reattach the cap.

3. Replace Thermostat (if faulty)

Drain the engine coolant into a suitable container.
Remove the thermostat housing bolts using a socket set.
Take out the old thermostat and replace it with the new one, ensuring it is oriented correctly.
Reattach the thermostat housing and torque the bolts to the manufacturer's specifications (typically around 15-20 ft-lbs).
Refill the coolant system with the previously mixed coolant.

4. Inspect and Replace Water Pump (if necessary)

Remove the serpentine belt using a belt tensioner tool.
Unbolt the water pump from its housing using a socket set.
Inspect the water pump for signs of wear or leaks; replace if necessary.
Install the new water pump, ensuring proper alignment and torque specifications.
Reattach the serpentine belt, ensuring it is routed correctly.

5. Test Radiator and Hoses

Inspect the radiator for any blockages; clean if necessary.
Check all coolant hoses for cracks or leaks; replace any damaged hoses.
Reattach all components and refill coolant if needed.
