I am due for a radiator drain and refill. I was curious about the best radiator flush product available today. Any suggestions?

Most radiator flush products are acid or alkaline-based. I would recommend avoiding them unless you think there's some serious scale build up or you've had contamination like oil/fuel in your coolant.

i have used a couple different ones. - I have had best luck so far with cummins restore.
