I wouldn't use Araldite on a joint exposed to heat cycling. A few years
ago
I used it to re-affix the plastic nozzles in several hot water taps
around
the house. Within a few months the Araldite had become brittle and was
coming away in chunks.

Interesting - a few years ago I had a leaking radiator (domestic, not
automotive) which had rusted through at a bottom corner. My bodge was to
wire brush it, which exposed several pin holes, then dip some self tappers
in Araldite and screw them in. Lasted the five or so years I lived there,
and there must have been a fair bit of heat cycling.

And I once had a hairline crack in the ally cylinder head of a Rover P4,
running from the spark plug hole to the exhaust valve seat of one cylinder,
that let compression through into the water. I used a triangular file to
open the edge of the crack and filled it with araldite. It fixed the leak
and was still good nearly 1000 miles later when I finally found a
replacement head. That must have had a fair bit of heat cycling too.
