Hello, I'm Danny.

I would just use a cooling system flush and cleaner like the Prestone brand. I've attached a picture below and it's available at Walmart for $4.00 Hope this helps and let me know if you have any further questions about this or tips on how to flush the system. Hope this helps and thanks for using 2CarPros.

Hello, no I would not do that. Just drain the system and replace the coolant with the recommended type of coolant. Make sure you mix the coolant with 50% water. Or you can buy premixed coolant.
