You might find a short fairly quickly that way. If you don't see anything obvious, setup your multi-meter for current/amps and with the battery reconnected and with the circuits "on" measure the current with the leads across the fuse terms and see if Fuse 5 is drawing too much current. Sometimes a fan motor that is loaded down (dry or worm bearings) will run high amps and blow the fuse by weakening it over time. Other times the current will spike and then again maybe it just blows when it turns on if there's an intermittent short across the windings. This particular Fuse 5 is the input/supply for the switching contacts for the cooling fan relay so it is possible the relay could be causing the spike/short/or ?. I do not have the relays memorized but after you locate it if there is another circuit with the same relay part number you could sub or swap them and see if the failure follows the relay.
Well, there's some stuff to try, post your results and if you don't find the problem we'll think of some more stuff to try.
When was the last time the fuse blew? Just curious. In the mean time I'll check in RAVE and see if there is something else I can think of to try.

I suspected the injectors in my first post. Oh well.

Could be oil, if from the crankcase vent system, see page from RAVE, the one on the passenger side has that oil separator that needs to be cleaned out with carb cleaner from time to time, or it will make pressure and vent oil in several places.
Could also be coolant from # 6 or # 7 on attached cooling diagram.
Good news is both are cheap fixes!
