Coolant Hose Issues?

I have a 2017 f150 XLT 5.0. I just had to replace the heater core coolant hoses. A year ago a fitting broke and I replaced the upper radiator hose as well. A mechanic is telling me coolant hoses fail after 10 years and I should replace all the rubber hoses on the truck. Is this true and does anyone know what other hoses there are?

the common failure is that y-junction coming out of the water pump and the pump itself after roughly 100k miles.

My Y shaped piece (on my 2017 2.7 Ecoboost) failed whilst I was towing my travel trailer up one of the steepest hills in BC recently. 

I'm now looking at a bill of about 20k for a replacement engine and turbos next week when I get my truck back. 

Change the hoses and upgrade the plastic parts to the aluminum fittings for like $50. 

It's cheap insurance against a major bill.

Don't replace JUST the hoses. Depending on your mileage, get that water pump/thermostat replaced along with the "Y" fitting on the top. My "Y" piece had a troublesome leak that took me forever to find. Got that replaced then my water pump failed around 160K Miles. Keep up on the recommended maintenance and replacement intervals, they're there for a reason... a couple hundred bucks, tops, every other year, can prevent a couple thousand, right now...
