Solution

1. Preparation

• Gather necessary tools and parts.
• Allow the engine to cool completely before working on the cooling system.
• Disconnect the battery to prevent any electrical shorts.

2. Replace Coolant

• Tools Required: Coolant flush kit, funnel, container for old coolant
• Drain the old coolant from the radiator and engine block.
• Refill with the manufacturer-recommended coolant mixture (typically a 50/50 mix of antifreeze and distilled water).

3. Replace Thermostat (if faulty)

• Tools Required: Socket set, torque wrench, gasket scraper
• Remove the thermostat housing by loosening the bolts.
• Remove the old thermostat and gasket.
• Install the new thermostat in the correct orientation and apply a new gasket.
• Reinstall the thermostat housing and torque to manufacturer's specifications.

4. Inspect and Clean Radiator

• Tools Required: Hose, radiator cleaning solution (if necessary)
• Remove any debris obstructing the radiator fins.
• Flush the radiator with water and a cleaning solution if necessary.
• Reinstall any components removed for access.

5. Check and Replace Cooling Fans (if necessary)

• Tools Required: Multimeter, socket set
• Test the electric cooling fans for proper operation using a multimeter.
• If the fans are not functioning, replace them according to the manufacturer's guidelines.
