Solution

1. Preparation

Gather tools and parts needed.
Ensure the vehicle is parked on a level surface.
Allow the engine to cool completely before starting.
Tools Required: Safety gloves, coolant, screwdriver, wrench set, OBD-II scanner.

2. Check Coolant Level

Open the hood and locate the coolant reservoir.
Remove the cap and inspect the coolant level; top off with the appropriate coolant if low.
Check coolant for contamination or discoloration.

3. Inspect for Leaks

Visually inspect all hoses connected to the radiator and engine for cracks or leaks.
Check the water pump for signs of coolant leakage.
Replace any damaged hoses or components as necessary.

4. Test Radiator Fan

Start the engine and allow it to reach operating temperature.
Observe the radiator fan; it should engage when the engine temperature rises.
If the fan does not activate, check the fan relay and fuses. Replace faulty components.

5. Replace Thermostat (if necessary)

Disconnect the negative battery terminal.
Drain the coolant to a safe level.
Remove the thermostat housing bolts and gently pull off the housing.
Replace the old thermostat with a new one, ensuring correct orientation.
Reassemble the housing and refill the cooling system with coolant.

6. Flush Radiator (if clogged)

Disconnect both hoses from the radiator.
Use a garden hose to flush out debris and buildup from the radiator.
Reconnect hoses, refill coolant, and check for leaks.
