Solution

1. Preparation

Park the vehicle on a level surface and engage the parking brake.
Allow the engine to cool completely before working on the cooling system.
Gather necessary tools and parts.

2. Check and Refill Coolant

Tools Required: Coolant funnel, hose clamps
Remove the radiator cap and inspect the coolant level. If low, refill with manufacturer-recommended coolant.
Inspect for leaks; if identified, replace damaged hoses or components.

3. Replace Thermostat (if faulty)

Tools Required: Socket set, torque wrench, gasket scraper
Drain the coolant from the radiator using the drain valve.
Remove the thermostat housing by unscrewing the bolts (check torque specifications).
Remove the old thermostat and replace it with a new one, ensuring the correct orientation.
Reinstall the thermostat housing and torque to specifications.
Refill the radiator with coolant.

4. Repair or Replace Cooling Fans

Tools Required: Socket set, multimeter
Inspect the cooling fan wiring and connectors for damage.
Test the fan motor with a multimeter to check for continuity.
If the fan is inoperable, remove it from the vehicle and replace it with a new fan assembly.

5. Flush the Radiator

Tools Required: Radiator flush kit, garden hose
Disconnect the lower radiator hose and direct it into a container.
Use a radiator flush chemical as per the product instructions, and flush the system with water until clear.
Reconnect the hose and refill the system with coolant.
