Do the "Fix Leak" products help with coolant leaks ?

Doesn't work on hoses. Depending on where it's leaking, it may be that you can splice in a short lenght of tubin that is a snug fit into the hose. This might get you by for a week oor two. You have to hope the hole is located in a straight section of the hose.
