On my 2002, I had to replace the radiator and coolant hoses as well as replacing the o-rings and cleaning up those coolant fittings in the middle of the engine's "V".
I can't remember offhand what year I did this; I think it was around 2013 or 2014 and somewhere well north of 70,000 miles. Or maybe I mentioned it in some old post on the topic. In any case, you probably have some miles to go; age affects the rubber, but not as much as heat. Just something to be aware of, and would be worth handling next time you have the tank off.
On any Vee, not just the 2002/03, 45K is right around the mileage that the fuel filter starts to clog and the TPS (throttle position sensor) fail, so I'd do the TPS and fuel filter bypass ASAP and PDQ if these haven't been provably done already.
And of course EVERY V-Strom will suffer dead headlights at some point due to that stupid, doomed-to-corrode, open, undersized connector in the left fairing "cheek". Get ahead of this, and while you're in there check, clean, and protect all the connectors on the bike. Doesn't take long.
