Solution

1. Preparation

• Gather all necessary tools and parts before starting.
• Ensure the engine is cool to avoid burns.
• Disconnect the battery to prevent electrical shock.

2. Coolant Level Check

3. Inspect and Replace Thermostat

• Tools Required: Socket set, torque wrench
• Remove the thermostat housing by unscrewing the bolts.
• Take out the old thermostat and compare it with the new one for proper fit.
• Install the new thermostat, ensuring it is oriented correctly.
• Reattach the thermostat housing and torque to manufacturer specifications.

4. Flush and Replace Coolant

• Drain the old coolant from the radiator using the drain valve.
• Rinse the system with water until it runs clear.
• Close the drain valve and refill with new coolant mixture.

5. Check and Replace Water Pump (if necessary)

• Tools Required: Socket set, drain pan
• Remove the serpentine belt from the water pump.
• Unbolt and remove the water pump.
• Clean the mounting surface and install the new pump, ensuring proper alignment.
• Reinstall the serpentine belt and torque to specifications.

6. Radiator Fan Inspection and Repair
