Solution

1. Preparation

Gather tools and materials needed for repair.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to avoid electrical hazards.

2. Coolant System Inspection

Sub-step 1: Remove the radiator cap (ensure engine is cool).
Sub-step 2: Visually check for any leaks around hoses, the water pump, and the radiator.
Sub-step 3: If leaks are found, replace damaged hoses or the water pump as necessary.

3. Thermostat Replacement

Sub-step 1: Drain the coolant from the radiator into a suitable container.
Sub-step 2: Locate the thermostat housing (typically near the engine block).
Sub-step 3: Remove the bolts securing the thermostat housing using a socket set.
Sub-step 4: Remove the old thermostat and clean the mating surfaces.
Sub-step 5: Install the new thermostat with the correct orientation and replace the housing.
Sub-step 6: Refill the cooling system with the appropriate coolant type.

4. Radiator and Cooling Fan Check

Sub-step 1: Inspect the radiator fins for debris or blockages and clean if necessary.
Sub-step 2: Test the cooling fan by starting the engine and allowing it to reach operating temperature; check if the fan engages.
Sub-step 3: If the fan does not operate, replace the fan motor or the relay as needed.
