i suggest you get a strobe light to do this
incase you turn a little too much, wont have any way to get the angle back
i agree with you that you should change old hardened hoses
old hoses have the tendancy to fail and when one does fail (its not IF,...but rather WHEN ) and say you are cruising on the highway at 110kmh, in a minute or two your engine block temp will start to rise...a minute or so later, your engine will most likely seize
when this happens, you kill your pistons and your cylinders
possibly break a conrod or two and even bend your crank shaft
worst case scenario, u even crack your cylinder head and chip the block
so for a few bucks, you might as well change the hoses

but what tham said is also correct
there will be some crap on the metal parts when the hose is removed
when you go to buy your hoses, get some high temp silicone gasket maker (red silicone)
after you pull off the hoses, use a SMALL BRASS wire brush (its softer than steel brush) to brush the metal and clean off any gunk stuck on
u can use a flat screwdriver or testpen VERY GENTLY to pick of stubbourn bits
its only cast alloy and it scratches very easily
a bad scratch will result in a leak path which will only get worse
after its nice and clean, wipe it off with a dry cloth
next, get the hose you want to fix ready
smear some red silicone all around the metal (less than 1mm...just a thin layer) and for the full length
leave a bit more around last bit towards the tip (3 or 4mm?)
now put the hose on
the hose should push the excess silicone down (always remember to have your jubliee clips on the hose so you dont have to pull out the hose again)
once the hose is in place and you have check to see that the other end is in the right position (if not twist the hose a bit till its just right), tighten the jubliee clip to about 95%
wipe away any access silicone to make it neat
do this for all your tubes and then leave them for about 30minutes for the silicone to set
then go back and tighten the last 5% (its basically 1/8 of a turn)
the silicone should fill in all the pits and holes (if any) and let you have a good solid seal until your next change

never loosen the jubliee clips unless you have to, in which case you will have to clean it up with the brush etc again and reapply the silicone
if you forget to put in a jubliee clip and have to pull out the hose again, reapply the layer of silicone before refitting the tube
