Solution

1. Preparation

Gather necessary tools and parts.
Ensure the engine is cool before starting to avoid burns.
Disconnect the battery for safety.

2. Drain Old Coolant

Locate the radiator drain valve or petcock at the bottom of the radiator.
Place a drain pan underneath the radiator.
Open the drain valve and allow the old coolant to completely drain out.

3. Flush the System

Close the drain valve once all coolant has drained.
Fill the radiator with a mixture of water and a radiator flush product according to the manufacturer's instructions.
Run the engine with the heater on high for about 10-15 minutes to circulate the flush.
Turn off the engine and allow it to cool, then drain the flush solution from the radiator.

4. Refill with New Coolant

Close the drain valve again.
Mix the appropriate type of coolant with distilled water according to the owner's manual specifications.
Fill the radiator with the new coolant and top off the reservoir.

5. Bleed the Cooling System

Start the engine and allow it to reach operating temperature.
With the heater set to maximum, check for air bubbles in the coolant reservoir.
Add coolant as needed to ensure the system is full and free from air pockets.
