Radiator hoses replacement interval?

[Senseless]

What is the recommended time or mileage to replace all the radiator hoses? My '12 S4 has 63,000 miles with the original set and I do some long distance highway travel.

I don't think I've ever needed to replace radiator hoses on anything in my life.

Every 20k or 25 years....whatever comes first...

Never?

Following along on this forum, but wanted to chime in. I have a B6 A4 with almost 150,000 miles on it and it is 11 years old. Original hoses. Hope this helps, but I might want to buy your car if you want to sell it. Like the way you think. :)

150,000 miles; pretty good! I have had radiator hoses fail and conventional wisdom used to be replace every 5 years. Maybe Audi is using some super quality rubber or the pricy pink antifreeze extends the life?

My previous b7 A4 was at 150k/10 years when I sold it, and had never had an issue with radiator hoses either.
