How often do you change your coolant? I change hoses about every 10 years now, in conjunction with the coolant change. I do coolant changes about every 5-6 years now. So I change hoses on every other coolant change, though for some reason, I haven't changed any of the hoses on my 97 Nissan PU.
With modern aluminum heads, you don't want to overheat your engine. The worse thing is if you have an oil leak that is putting oil on a hose. That will ruin a hose in short order.
Check the condition of your hoses at least every oil change. Also check the seal between the tanks and the core of the radiator.
