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

Post by cn90 » Tue Jan 23, 2018 9:14 pm

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...

https://www.pelicanparts.com/techarticl ... cement.htm


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?

1. I suppose you don't. But there's no reason it should at all unless your coolant is in terribly bad shape or you're using corrosive oil.
2, 3. As long as any other part of the cooling system, that is mostly long enough for other stuff to break first.

I don't think we have a single documented oil cooler failure on the bastard and P2 style oil cooler on MVS?

I replaced my hoses on. Preventative basis after 17 years and they were in great shape. No sign of failures. I dabbed. My own protective chafe layer with a heavy wrap product and wrote up a thread about it

I've never heard of it failing on Swedish forums either.
