Solution

1. Preparation

Gather necessary tools and parts.
Ensure the engine is cool before beginning work.
Disconnect the battery to avoid any electrical issues during repairs.

2. Inspect and Replace Coolant

Sub-steps:
1. Remove the coolant reservoir cap and check the coolant level.
2. If low, top off with the manufacturer's recommended coolant mixture (usually a 50/50 mix of coolant and distilled water).
3. Inspect for coolant contamination; if dirty, drain the system completely.
4. Refill the system with new coolant.

3. Replace Thermostat

Tools Required: Socket set, torque wrench
Sub-steps:
1. Locate the thermostat housing connected to the engine.
2. Remove the bolts securing the thermostat housing using a socket set.
3. Carefully lift the housing and remove the old thermostat.
4. Clean the mating surfaces, install the new thermostat, and replace the housing, tightening the bolts to the manufacturer's specifications.

4. Check and Replace Radiator Fan

Sub-steps:
1. Inspect the fan for physical damage or debris obstruction.
2. If damaged, disconnect the wiring harness and remove the fan assembly.
3. Install the new radiator fan by securing it in place and reconnecting the wiring harness.

5. Inspect and Replace Hoses

Sub-steps:
1. Examine all coolant hoses for cracks or leaks.
2. If any hoses are damaged, remove the clamps and replace the hoses.
3. Ensure all connections are secure and leak-free.
