One persistent problem on my tired old 1995 Ford V6 Moandeo is slight 
leakage from around the cooling system hoses, most notably around the hose 
connections to the in-line thermostat housing.

I've tried unsuccessfully to stop the leaks by thoroughly cleaning the 
aluminium spigots, fitting new hose clips and praying.  As the leakage has 
been minimal, I finally decided to ignore it.

My radiator has just (literally) collapsed. The bottom steel U-section 
radiator cross-member has snapped and the whole cooling matrix is sagging 
and heading south!

For some reason, the radiator cross-member has two large vee-cuts for almost 
the full width, one at each end of the radiator.  This seriously weakens the 
cross-member and it is at one of these vee-cuts that the cross-member has 
snapped.

I now have to disturb a lot of hose connections next weekend.

Can anyone recommend a good hose sealant that I could apply to the aluminium 
(and steel) spigots before I refit the hoses?  There must be something that 
will seal the slight coolant leaks without damaging the rubber hose.

I've got Hermetite and Hylomar blue in stock.
