Solution

1. Preparation

Gather tools and materials:
- Drain pan
- Radiator flush solution
- Hose
- Funnel
- Safety gloves and goggles
Ensure the engine is cool and park the vehicle on a level surface.

2. Drain Coolant

Locate the radiator drain plug at the bottom of the radiator.
Place the drain pan underneath the radiator drain plug.
Open the drain plug and allow the coolant to completely drain into the pan. Ensure to dispose of the old coolant properly.

3. Flush System

Close the drain plug once the old coolant has drained.
Mix the radiator flush solution with water according to package instructions and pour it into the radiator using a funnel.
Start the engine and let it idle for 10-15 minutes with the heater on full to circulate the flush solution. Maintain a watchful eye on the temperature gauge to avoid overheating.

4. Drain Flush Solution

Turn off the engine and allow it to cool.
Repeat the draining process by opening the drain plug again and letting the flush solution drain completely.

5. Refill with New Coolant

Close the drain plug securely.
Mix the appropriate coolant with distilled water as per the manufacturer’s specifications, typically a 50:50 ratio.
Using a funnel, refill the radiator and reservoir with the new coolant mixture.

6. Bleed Air from System

Start the engine and run it with the radiator cap off until the thermostat opens (you'll see coolant flow).
Keep an eye on the coolant level, adding more as necessary to ensure there are no air pockets.
Once the engine reaches operating temperature, replace the radiator cap.
