Solution

1. Preparation

Gather tools and parts needed.
Ensure the engine is cool before starting work.
Disconnect the battery to prevent electrical issues.

2. Coolant Level Check and Top-Up

Locate the coolant reservoir and remove the cap.
If low, use a 50/50 mix of coolant and distilled water to fill to the proper level.
Replace the cap securely.

3. Thermostat Replacement

Tools Required: Socket set, Torque wrench, Gasket scraper.
Drain coolant from the radiator using the drain plug.
Remove the thermostat housing bolts (usually 10-12 Nm torque).
Lift the thermostat out and replace it with a new one, ensuring the correct orientation.
Clean the gasket surface and install a new gasket.
Reinstall the thermostat housing and torque the bolts to manufacturer specifications.

4. Water Pump Inspection/Replacement

Tools Required: Socket set, Pliers, Drain pan.
Disconnect any hoses connected to the water pump.
Remove the water pump mounting bolts and carefully pull off the pump.
Inspect the impeller and housing for damage.
If necessary, install a new water pump, ensuring proper alignment and sealing.

5. Radiator Inspection and Cleaning

Remove any debris obstructing the radiator fins.
Check for signs of leaks or corrosion on the radiator.
Flush the radiator with a garden hose if necessary, ensuring water flows freely.

6. Cooling Fan Check

Tools Required: Multimeter.
Start the engine and let it reach operating temperature.
Observe the cooling fans; they should engage when the engine reaches the specified temperature.
If fans do not operate, test the fan relay and associated fuses.
