Solution

1. Preparation

Gather necessary tools and parts.
Ensure the engine is cool before starting.
Disconnect the battery to ensure safety during work.

2. Check and Replace Thermostat

Tools Required: Socket set, coolant catch pan
Remove the engine cover if necessary to access the thermostat.
Drain coolant into a catch pan.
Remove the thermostat housing bolts and detach the housing.
Take out the old thermostat and replace it with a new one.
Reassemble the thermostat housing and tighten bolts to the manufacturer's torque specifications.

3. Inspect and Repair Coolant Leaks

Tools Required: Hose clamp pliers, socket set
Visually inspect all hoses connected to the cooling system for cracks or leaks.
Replace any damaged hoses with new ones.
Tighten any loose hose clamps to ensure a secure fit.

4. Check and Repair Radiator Fan

Tools Required: Multimeter, socket set
Start the engine and monitor the radiator fan for operation.
If the fan does not activate, check the fuse and relay associated with the cooling fan.
Test the fan motor with a multimeter. If faulty, replace the fan motor.

5. Flush and Refill Cooling System

Tools Required: Coolant catch pan, funnel
With the engine cool, remove the radiator cap and drain the old coolant completely.
Flush the system with clean water until it runs clear.
Refill with manufacturer-recommended coolant mixture.
