naturally, if you have enough miles, replacing the upper and lower radiator hoses wouldn't be a bad idea.
in my case, i went ahead and replaced the belts as well since they are easily accessed once those billion of bolts that hold on the skid plate are removed.
for all the above work, no need to jack up the vehicle, you can do it all by just driving the front wheels up on a 2x8 and reaching under.
IMHO, the important thing is that your temp gauge is steady after the service. Then all you have to do is check the level when the car is hot and top off. Repeat after the car has sat and cooled until the level no longer drops. Very easy and a no-brainer really. The problem with the "old skool" method, is that the radiator cap is no longer the highest point in the system, the air relief valve is, so you wouldn't be able to get all the air our using that method.
