Volvo 2.5T Engine: Oil Cooler and/or Hoses x2 question

[cn90]

I have a 2005 XC90 2.5T with 110K miles, since this is a common topic in later models with oil cooler mounted in the back side of the engine, I want to ask a few question after I read the Pelican article on Oil Cooler...

1. How do you know it corrodes INTERNALLY?

2. How long does the oil cooler last?

3. The Cooler Hoses x2: how long do they last?
