Solution

1. Preparation

Gather necessary tools and parts.
Allow the engine to cool completely before working on the cooling system.
Disconnect the battery to prevent any electrical issues.

2. Coolant Level Adjustment

Remove the radiator cap (only when the engine is cool).
Add the appropriate type of coolant to the radiator and overflow reservoir to the recommended level.
Replace the radiator cap securely.

3. Inspect and Replace Thermostat (if faulty)

Locate the thermostat housing on the engine.
Remove the bolts securing the thermostat housing using a socket set.
Take out the old thermostat and replace it with a new one, ensuring correct orientation.
Reattach the thermostat housing and tighten bolts to manufacturer specifications (usually 15-20 ft-lbs).

4. Flush and Replace Coolant

Locate the radiator drain plug and open it to drain old coolant into a container.
Flush the radiator with water to remove any debris. Close the drain plug afterward.
Fill the radiator with a 50/50 mixture of coolant and distilled water.
Start the engine and let it reach operating temperature, checking for leaks.

5. Inspect and Repair Cooling Fans

Check the electrical connections to the cooling fans for corrosion or damage.
Test the fans by applying direct power to them to ensure they operate correctly.
Replace any faulty fans or damaged wiring as necessary.
