Solution

1. Preparation

Gather tools and parts necessary for repair.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the battery to prevent electrical issues.

2. Inspect and Replace Coolant

Sub-steps:
1. Remove the coolant reservoir cap carefully to avoid steam burns.
2. If the coolant level is low, top it up with the appropriate coolant type as specified in the owner's manual.
3. If the coolant is contaminated or old, drain the system completely.
4. Refill the cooling system with a mixture of coolant and distilled water as per the manufacturer's recommendations.

3. Replace Thermostat (if faulty)

Sub-steps:
1. Locate the thermostat housing, typically near the engine.
2. Remove the bolts securing the thermostat housing using a socket wrench.
3. Carefully lift the housing and extract the old thermostat.
4. Clean the mating surfaces of the housing and engine.
5. Install the new thermostat, ensuring the correct orientation.
6. Reattach the thermostat housing and torque the bolts to the manufacturer's specifications.

4. Repair or Replace Radiator Fan

Sub-steps:
1. Test the fan by connecting it directly to the battery; it should spin freely.
2. If the fan does not operate, replace it with a new fan assembly.
3. If the fan works, check the fan relay and wiring for faults.
4. Reconnect any connectors and secure the fan assembly back in place.
