Radiator/heater hoses--when to change

[hoser]

Summer is coming up and my 100 is approaching 100k miles and 8 years of age. I don't see any radiator/heater hose changing interval in the maintenance schedule. The upper hose is getting soft while the bottom one seems okay. I haven't even looked at the heater hoses yet. Hopefully it's nothing like the 80 series. Probably a good time to change the radiator cap too.

When is everybody changing their hoses?

Changed all hoses and belts at 7 years but mine spent its life in southern AZ.

A good time will probably be when you do the timing belt, since you will be removing a lot of stuff anyhow and replacing the coolant. Make sure to get all the little hoses as well.

I did mine with the timing belt @ 107k. Be sure to replace the coolant pipe hoses when you are in there. (They run up-down in front of the timing belt...)
