Solution

1. Preparation

Gather necessary tools and parts.
Ensure the engine is cool before beginning work.
Disconnect the negative battery terminal to prevent electrical short circuits.

2. Coolant Level Check

Remove the radiator cap carefully (if applicable).
Top off coolant with the manufacturer-recommended type (usually a 50/50 mix of antifreeze and distilled water).

3. Replace Thermostat (if faulty)

Tools Required: Socket set, torque wrench, gasket scraper
- 1. Drain the coolant from the radiator until it reaches below the thermostat level.
- 1. Remove the thermostat housing bolts with a socket set.
- 1. Take out the old thermostat and replace it with a new one.
- 1. Reinstall the housing and torque bolts to the manufacturer's specifications (usually around 15-20 Nm).
- 1. Refill the coolant system with the appropriate mixture.

4. Inspect and Replace Water Pump (if necessary)

Tools Required: Socket set, torque wrench, coolant catch pan
- 1. Drain the coolant completely into the catch pan.
- 1. Disconnect the water pump's electrical connector and hoses.
- 1. Remove the water pump mounting bolts with a socket set.
- 1. Take out the old water pump and install the new one, ensuring alignment with the gasket.
- 1. Torque the mounting bolts to the manufacturer’s specifications (typically around 10-15 Nm).
- 1. Reconnect the hoses and electrical connector.

5. Check Radiator Fan Function

Tools Required: Multimeter
- 1. Reconnect the battery terminal.
- 1. Start the engine and let it reach operating temperature.
- 1. Use a multimeter to check for voltage at the fan connector when the engine is hot. If no voltage, the relay or fan may need replacement.
