I have blown a few hoses too, it is most likely old age.  If
your temps are funny and you have tried everthing you can think
of to fix it and nothing worked, replace the water pump, I did
this after many failed attempts at getting my temps right,
works like a champ now :) (a OEM pump from mark is $43, housing
and impeller).  

Another less desireable thing it may be is a
blown head gasket, I am not totally sure, but I think I head
that overheating and bad head gaskets are related.  

I think I also heard that if your overflow tank cap is bad then it 
will cause problems like this, the pressure will build because
of the bad cap and blow hoses.  1.5 Hrs for a thermostat!!! I can 
do it in 15 min (with p/s) ;).  O, and one more thing, there is
only one thermostat, it's in the water pump housing under that
plastic cover that the lower rad hose connects to.  So don't 
buy that crap about a termostat on the block?????.

HTH!
