What I Look for in Dike Stop Leak

I want a product that matches the problem, whether it is a small coolant leak, a minor seal issue, or a general maintenance fix. I also pay attention to whether the product is made for my specific system, because using the wrong formula can cause more trouble than it solves.
Why I Check Compatibility First
