Solution

1. Preparation

Tools Required: Socket set, coolant funnel, OBD-II scanner, torque wrench, thermometer.
Ensure the engine is cool and the vehicle is parked on a level surface.

2. Coolant Inspection

Sub-steps:
1. Remove the radiator cap (only when cool).
2. Check the coolant level; if low, top it up with the appropriate coolant mixture (50/50 water and antifreeze).
3. Inspect for any visible leaks or damage in the hoses and connections.

3. Thermostat Replacement

Sub-steps:
1. Drain the coolant from the radiator using a drain pan.
2. Disconnect the thermostat housing using the socket set.
3. Remove the old thermostat and inspect for wear or blockage.
4. Install a new thermostat, ensuring the correct orientation.
5. Reconnect the thermostat housing and torque to manufacturer specifications.

4. Water Pump Inspection

Sub-steps:
1. Visually inspect the water pump for leaks or damage.
2. Check the drive belt for cracks and ensure it is tight.
3. If the pump shows signs of failure, drain the coolant and remove the pump by unbolting it.
4. Install the new water pump, ensuring a proper seal, and torque bolts to specification.

5. Radiator Cleaning or Replacement

Sub-steps:
1. Check the radiator for any blockages or debris.
2. Use compressed air to clean any external debris from the radiator fins.
3. If the radiator is damaged or severely clogged, remove it and replace it with a new unit.
4. Reattach the hoses and refill the cooling system with coolant.
