Solution

1. Preparation

Gather tools and parts necessary for repair.
Park the vehicle on a level surface and turn off the engine.
Allow the engine to cool completely before working on the cooling system.
Tools Required: Socket set, screwdrivers, OBD-II scanner, multimeter, coolant recovery funnel.

2. Inspect and Replace Coolant

Sub-steps:
1. Open the hood and locate the coolant reservoir.
2. If the coolant is low, top it off with the manufacturer-recommended coolant mix.
3. If there are signs of contamination or old fluid, drain the old coolant from the radiator using a drain pan.
4. Refill the radiator with new coolant and ensure the system is bled of air.
5. Safety Warning: Never open the radiator cap when the engine is hot to prevent burns.

3. Replace Thermostat (if faulty)

Sub-steps:
1. Disconnect the negative battery terminal.
2. Remove the thermostat housing by unscrewing bolts using the socket set.
3. Take out the old thermostat and clean the mating surfaces.
4. Install the new thermostat with a new gasket, ensuring correct orientation.
5. Reattach the thermostat housing and reconnect the negative battery terminal.

4. Repair or Replace Radiator Fan

Sub-steps:
1. Disconnect the electrical connector from the radiator fan.
2. Use the OBD-II scanner to check if the fan turns on at the specified temperature.
3. If the fan does not operate, check the fan relay and fuses, replacing them if necessary.
4. If the fan motor is faulty, remove it from the radiator and replace it with a new unit.

5. Inspect and Replace Water Pump (if necessary)

Sub-steps:
1. Check for any signs of coolant leaks around the water pump.
2. If the water pump is suspect, drain the coolant and remove the pump following manufacturer-specific procedures.
3. Install the new water pump and torque the bolts to the specified value.
4. Refill the cooling system with coolant and bleed the air from the system.
