Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to avoid any electrical issues.

2. Check and Refill Coolant

Remove the radiator cap (only if engine is cool).
Inspect and refill coolant to the proper level using a 50/50 mix of antifreeze and distilled water.
Replace the radiator cap securely.

3. Inspect and Replace Thermostat

Locate the thermostat housing (usually near where the upper radiator hose connects to 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 it is oriented correctly.
Reattach the housing and torque bolts to the manufacturer's specification (typically around 15-20 ft-lbs).

4. Check and Replace Radiator Fan

With the engine running, observe if the radiator fan engages when the engine reaches operating temperature.
If the fan does not operate, disconnect it and replace with a new fan assembly.
Reconnect the electrical connectors and test the operation again.

5. Flush Radiator (if clogged)

Disconnect the lower radiator hose and allow coolant to drain.
Use a radiator flush solution to clean the system, following the instructions on the product.
Refill the system with fresh coolant and bleed air pockets if necessary.
