Solution

1. Preparation

Tools Required: OBD-II scanner, coolant tester, torque wrench, socket set, multimeter, safety glasses.
Allow the engine to cool completely before starting any work to prevent burns.

2. Coolant System Inspection

Sub-steps:
1. Open the hood and locate the coolant reservoir.
2. Inspect for coolant levels; if low, top off with manufacturer-recommended coolant.
3. Visually inspect hoses for cracks or leaks and replace any damaged hoses.

3. Thermostat Replacement

Sub-steps:
1. Drain the coolant from the radiator using a drain pan.
2. Remove the thermostat housing bolts using a socket set.
3. Take out the old thermostat and clean the mounting surface.
4. Install the new thermostat with the spring side facing the engine.
5. Reattach the thermostat housing and torque the bolts to the manufacturer's specifications.

4. Water Pump Inspection/Replacement

Sub-steps:
1. If the water pump is suspected to be faulty, drain the coolant again.
2. Remove the serpentine belt using a wrench to relieve tension.
3. Unbolt the water pump from its mounting and remove it.
4. Install the new water pump and ensure proper alignment before tightening bolts to specification.
5. Refill the cooling system with the appropriate coolant and bleed any air from the system.

5. Cooling Fan Operation Check

Sub-steps:
1. Start the engine and allow it to reach operating temperature.
2. Use a multimeter to check for voltage at the fan connector when the engine temperature exceeds normal operating range.
3. If the fan does not engage, replace the fan motor or the temperature sensor as necessary.
