and, furthermore, patching a radiator hose on a modern vehicle is pretty

a place that could order a hose and not charge me $400 for "installation",
but that kind of patch won't work if you let the system operate normally.

I wonder if that is what they meant by patch?

Ah, I dunno, but thanks for the tip in any case; never thought to leave the
cap off to keep the pressure from blowing out the temp patch.
