About to replace the water pump and wondering if I should do the hoses as well. It’s an extra $130(RockAuto, GM OEM) that I’d rather not spend but I’d also rather not break down. The van is a 2013 with 168k. The hoses look/feel good but I know they can have invisible internal failures. As far as I can tell they are factory hoses. How long do these factory hoses usually last?

 

General rule about original battery, wiper blades etc. they put the low end things on new vehicles, usually get two years out of a battery etc. I have an 02 Mazda that still has original hoses, they best answer I can give is you have to decide. Since you have to drain the system, with 168K, might be a strong consideration to replace now.

 

In my experience anything rubber isn't going to last more than about 10 years. Is normally more of a time thing than it is mileage.

 

If it looks fine and works fine, then I wouldn't try to "fix" it.

People who talk about "invisible failures" are usually trying to sell you something.
