I think you're fine for now but if you don't want to risk it either go for the by-pass or replace the radiator. Cheap insurance. The Nissan "warranty" on these is laughable once you're passed 80k miles. Making me front $2,500 or $3,500 depending on miles is not much of a warranty. Once you swap out the radiator and flush the coolant, I'd do a drain/fill on the transmission as well. Use the correct fluid and you should be good for awhile. Most drain/fill the tranny around 30k mile intervals. You probably should do the differentials and transaxle as well. My guess is the prior owner didn't do much maintenance.
