Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to ensure safety.

2. Check and Refill Coolant

Locate the coolant reservoir and remove the cap.
If the coolant level is low, mix the appropriate coolant type (refer to the owner's manual) with distilled water (50/50 mix).
Fill the reservoir to the recommended level and securely close the cap.

3. Inspect and Replace Thermostat (if faulty)

Remove the thermostat housing using a socket set.
Take note of the orientation and position of the old thermostat for reinstallation.
Replace it with a new thermostat, ensuring proper orientation.
Torque the housing bolts to the manufacturer's specifications (typically around 10 Nm).

4. Check and Replace Water Pump (if leaking or malfunctioning)

Drain coolant from the radiator into a suitable container.
Remove the serpentine belt using a belt tensioner tool.
Unbolt the water pump from the engine using the appropriate socket size.
Install the new water pump with a new gasket and torque bolts to specifications.
Refill the coolant system after installation.

5. Inspect and Repair Radiator and Hoses

Check all hoses for cracks or signs of wear; replace any damaged hoses.
Inspect the radiator for blockages or leaks and replace if necessary.
Use a radiator flush solution if the cooling system is contaminated.

6. Test Cooling System Operation

Reconnect the battery and start the engine.
Allow the engine to reach operating temperature while monitoring the coolant temperature.
Check for leaks and ensure the radiator fan engages when necessary.
