My wife's '97 Safari Van had one stock from GM. "Had" is the
operative word..a goofball at the local lube shop rounded the
shoulders of the hex head trying to remove it with a pair of
channel locks. But I digress..anyway, the magnet did attract
small metal particles but they were so small that they felt like graphite
between my fingers. I am not sure if that is an indication of little
wear - good - or the magnet not working. Anyway, the only likely harm
if it doesn't help is wasting the few dollars you spend (less than a
burger?)
