I have a 2003 Accord with about 90,000 miles on it. The hoses were never replaced and I figured I might as well change them before I have any problems. I have started to do a bunch of work myself and I feel pretty cofortable in changing them.

I was just wondering if I should also change the hoses to and from the heater core or should I just stick with changing the upper and lower radiator hoses?
Also is there anything in particular I should watch out for when changing the hoses (common problems that people run into etc...)

Thanks
