Solution

1. Preparation

Gather necessary tools and parts for the repair.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the negative battery terminal for safety.

2. Check and Replace Coolant

Tools Required: Coolant funnel, drain pan, gloves
Remove the radiator cap carefully to avoid pressure release.
Drain the old coolant into a drain pan.
Refill the system with the manufacturer-recommended coolant, ensuring the correct mix ratio.
Replace the radiator cap securely.

3. Inspect and Replace Thermostat

Tools Required: Socket set, torque wrench, gasket scraper
Remove the thermostat housing by unscrewing the bolts (follow torque specifications).
Take out the old thermostat and inspect it for proper operation (it should open and close as required).
Install a new thermostat with a new gasket, ensuring it is seated correctly.
Reattach the thermostat housing and torque bolts to specifications.

4. Inspect and Repair Cooling System Components

Tools Required: Inspection mirror, flashlight
Check all hoses for signs of wear or leaks. Replace any damaged hoses.
Inspect the water pump for any coolant leaks or unusual noises. Replace if necessary.
Clean the radiator fins and ensure no debris is blocking airflow.
