Gunk 10 Minute Radiator Flush quickly removes grease, scum, rust and scale. It is a fast, one step product that requires no neutralizer and contains no acids. This radiator flush is compatible with all cooling systems.
I used the Gunk Motor Medic 10-minute radiator flush to clean out my old radiator, and it worked wonders! The 11 oz size was just enough for my small car. Super easy to use, just pour it in and follow the instructions. My engine is running much cooler now!

Did Its Job but with Some Drama
I tried the Gunk Motor Medic flush, and while it did help clean my radiator, the instructions could've been clearer. Took me a few tries to get the timing right. No leaks, though, so I'm happy with the performance overall.

Not Impressed with the Results
I was expecting more from this radiator flush. After using the Gunk Motor Medic, my engine didn't feel significantly different, and I noticed some leftover gunk. Maybe my system was just too clogged?
