Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is cold.
Disconnect the battery to avoid electrical issues.

2. Coolant System Inspection

Sub-steps:
1. Remove the radiator cap and inspect for proper coolant level; refill if necessary.
2. Check all hoses for cracks or leaks, particularly the upper and lower radiator hoses.
3. Inspect the water pump for leaks or corrosion.

3. Thermostat Replacement (if faulty)

Sub-steps:
1. Drain the coolant from the radiator into a clean container.
2. Remove the thermostat housing by unscrewing the bolts (torque specs: 10-15 ft-lbs).
3. Replace the old thermostat with a new one, ensuring correct orientation.
4. Reattach the housing and torque bolts to specified values.

4. Radiator Inspection and Cleaning

Sub-steps:
1. Remove the radiator from the vehicle if blockages are found.
2. Clean the radiator fins using compressed air or a soft brush.
3. Inspect for any signs of internal blockage; replace if necessary.

5. Cooling Fan Operation Check

Sub-steps:
1. Turn on the ignition (do not start the engine).
2. Activate the air conditioning; the cooling fans should engage.
3. If fans do not operate, check the fan relay and fuses, replacing any faulty components.
