My friends that run an honest radiator shop say no way. Stop leak is a tool
you can use when you want to dump a dying car on a sucker within a few
weeks. It will seal pinholes, but only for a short period after it is
installed, then it evenly gums up the entire system, primarily the radiator
and heater core.

Using a flush can cut some of that crud back out, but you should have never
needed the flush in the first place. If you maintain your fluids, and modern
radiator fluids last for years, then there will be little or nothing to

If your radiator develops a pin leak, then odds are there are a hundred more
pin leaks about to develop. Time to replace it. If it sustains damage, then
it may be worth repairing. If a clamp starts to leak, address it. If the
pipe or fitting is cleaned and prepped before the hose went on, if the hose
and clamp are in good condition, and if the person doing the assembly knows
what they are doing, its unlikely to leak. When was the last time you found
a leak in a new car? They have cooling systems that were assembled from
scratch just miles before.

IMHO, stop leak is a tool for sloppy mechanics, used car salesmen, and the
cash strapped single mother looking for a too-good-to-be-true solution.

I had my DeLorean's antifreeze flushed and changed recently at a garage that
has kept my family cars going for over 30 years. I was advised that they
always add a can of Bar's Leak after any radiator flush. I advised them not
to put in a can, although I have never had reason to doubt their judgement
and competence over the years. I have always been pleased with their repairs
and service. They said the Bar's Leak will do no harm and will plug any pin
hole leak or loose clamp leak that may develop. Should I add a can for this
"insurance" or leave well enough alone and not add it. Thanks,  Rod 10921
