Replacing Cooling System Parts

[bwflorida]

2003 KJ Sport... need to do a radiator flush and am wondering if I should replace hoses, thermostat, etc. at the same time, just to bring everything up to date. Are there any other cooling system parts I should replace?

If doing a flush then yes and make sure to use only HOAT coolant,
top and bottom radiator hoses,
new MOPAR thermostat ,
while you're at it why not replace the belt and idler pulleys ( whole assembly ) as well
