Solution

1. Preparation

Gather tools and materials: OBD-II scanner, coolant, socket set, torque wrench, cleaning rags, and safety glasses.
Ensure the engine is cool to prevent burns.

2. Replace Low Coolant

Locate the coolant reservoir and check the level.
If low, add the appropriate coolant type as specified in the owner’s manual.
Check for leaks after filling and monitor the system during operation.

3. Replace Thermostat

Drain coolant from the radiator using a catch pan.
Remove the thermostat housing using a socket set (typically requires 10mm or 13mm sockets).
Replace the old thermostat with a new one, ensuring the correct orientation.
Reattach the thermostat housing and tighten to the manufacturer’s torque specification (generally around 15-20 ft-lbs).
Refill the cooling system with the appropriate coolant mixture.

4. Repair or Replace Cooling Fan

Inspect the cooling fan for any obstructions or damage.
If faulty, remove the fan shroud and disconnect the fan motor.
Install a new fan by reversing the removal steps, ensuring all electrical connections are secure.

5. Clean or Replace Radiator

Inspect the radiator’s condition for blockages or corrosion.
If needed, remove the radiator from the vehicle by disconnecting the hoses and mounting bolts.
Flush the radiator with a specialized cleaner or replace it with a new unit as necessary.
Reinstall the radiator, reconnect hoses, and refill the cooling system.
