I have had a plastic fan blade break and puncture the radiator. I think =
this was rather a fringe case, however. Autopsy revealed the fan had a =
molding flaw =E2=80=94 there was large bubble in the plastic right at =
the base of the blade that broke off =E2=80=94 it only lasted 307 miles =
from new. Also, it is doubtful that the blade would have seriously =
damaged the radiator if it hadn=E2=80=99t become trapped in the radiator =
shroud. As it was, it acted as a kind of rotary hammer, which was too =
much for the 50+ year-old brass core.
Anyway, as for Rick=E2=80=99s problem, if it doesn=E2=80=99t involve a =
head gasket leak (as suggested), then I think that leaves serious =
blockage in the block somewhere. Possibly this could be located with a =
thermo gun. I have had to remove freeze plugs and break up deposits with =
a pick in an old iron block V8 before.
