At 100K, it is probably a bit early for that operation. But, if you do:

Make sure the clamps at the radiator are in the identical position as before, a new position will probably crack the plastic. Also, don't over tighten the hose clamps.

If you are replacing hoses, replace the small hose from the overflow bottle as well. The heater hoses that go from the block to the firewall????

And don't be too cheap, $17 for a gallon of Volvo antifreeze isn't too much more than the $12 of brand X at the autoparts store.
