hoses are generally cheap. i say to buy a upper radiator spare hose, keep it in the trunk along with whatever tools you need to change them out. usually its the upper hose which feeds hot coolant into the rad that blows out first.
if you keep a spare with you. you can pretty much drive on the original until she blows.
i have the same mentality with accessory belts and idler pulleys or serpentine belt tensioner. keep the spares with you and whatever tools you need to change them. run the originals until they blow.
usually the only tools you need is a few screwdrivers and a basic set of box end wrenches. thats something that no motorist should be without reguardless.
on my stratus, its still got the original radiator hoses and the original a/c and alternator belt, and thats over 180,000 miles. the power steering belt has been replaced once, along with the idler for the a/c and alternator belt. the upper rad hose is bulging like a seagull that ate too many alka seltzers. but its still holding on. i may change it soon just because i KNOW its not got much life left, and being temporarily stranded on the side of the road and being late to whatever it is that i was driving to is no fun.
