Solution

1. Preparation

Gather necessary tools and parts.
Ensure the engine is cool before starting.
Disconnect the negative battery terminal for safety.

2. Inspect and Replace Thermostat

Locate the thermostat: Follow the upper radiator hose to the engine; the thermostat is typically housed near the engine block.
Remove the thermostat housing: Use a socket set to remove the bolts securing the housing. Carefully pry the housing off.
Inspect the thermostat: Check for damage or stuck position. If it doesn’t open when heated, replace it.
Install new thermostat: Ensure the new thermostat is oriented correctly and insert it into the housing.
Reattach the housing: Apply a gasket sealant if required and tighten bolts to the manufacturer's torque specifications (usually around 15-20 Nm).

3. Check and Repair Radiator and Hoses

Inspect radiator and hoses: Look for cracks, bulges, or signs of wear.
Replace damaged hoses: Use a hose clamp tool to remove and replace any damaged hoses.
Flush the radiator: Disconnect the lower radiator hose and flush the system to remove debris or buildup.
Reattach hoses: Securely clamp hoses back to their original positions.

4. Test Radiator Fan

Locate the fan: It is usually mounted directly on the radiator or can be part of the engine assembly.
Start the engine: Allow it to reach operating temperature.
Check fan operation: Listen for the fan to activate. If it does not, test the fan motor with a multimeter for continuity.
Replace fan: If faulty, disconnect the fan wiring harness, remove mounting screws, and install a new fan.
