My radiator plug mysteriously broke off and allowed my radiator to drain. What would cause that?
Also, is it repairable? it's on a 95 Cadillac Sedan DeVille.
The Plug was laying there. It's a winged type with a rubber flat washer and an 1/8" dia. shank that appears to have broken just after the threads. So I'm assuming the threaded portion
rock in the road,
heat expansion,
defective part,
someone took it out,
front end accident dislodged it,
its really still there, it all leaked from somewhere else.
