Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the battery to prevent any electrical shorts.

2. Inspect and Replace Thermostat

Sub-steps:
- Locate the thermostat housing (generally found near the engine block).
- Remove the bolts securing the thermostat housing using a socket set.
- Carefully remove the housing and take out the old thermostat.
- Clean the mating surfaces to ensure a good seal with the new thermostat.
- Install the new thermostat with the correct orientation.
- Reattach the thermostat housing and torque the bolts to manufacturer specifications.

3. Check and Replace Water Pump (if necessary)

Sub-steps:
- Drain the coolant from the radiator into a clean container.
- Remove the serpentine belt from the water pump pulley using a wrench.
- Unbolt the water pump from the engine block and remove it.
- Compare the old pump with the new one for compatibility.
- Install the new water pump, ensuring the gasket is properly seated.
- Torque the water pump bolts as per specifications.

4. Inspect and Flush Cooling System

Sub-steps:
- Refill the cooling system with a 50/50 mixture of coolant and distilled water.
- Start the engine and allow it to reach operating temperature while checking for leaks.
- Run the heater on high to help circulate coolant and remove air pockets.
- Monitor the temperature gauge and ensure it stabilizes within the normal range.
