Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the engine is cool before starting work.
Disconnect the negative battery terminal to avoid electrical shorts.

2. Check and Replace Coolant

Drain the coolant from the radiator by opening the drain valve or removing the lower radiator hose.
Flush the cooling system with water to remove any debris or contaminants.
Refill with the appropriate coolant mixture (usually a 50/50 mix of antifreeze and distilled water).
Bleed the system to remove any trapped air by running the engine with the radiator cap off until the thermostat opens.

3. Inspect and Replace Thermostat

Locate and remove the thermostat housing by unscrewing the bolts (usually requires a socket set).
Take out the old thermostat and inspect for any signs of failure (stuck closed/open).
Install the new thermostat (ensure it is oriented correctly).
Reattach the thermostat housing and torque the bolts to manufacturer specifications.

4. Inspect and Replace Cooling Fans (if necessary)

Disconnect the electrical connector from the cooling fan.
Remove mounting bolts securing the fan to the radiator.
Install the new cooling fan, ensuring it is properly secured and connected.
Reconnect the battery terminal.
