serpentine belt and hose replacements
When do you replace serpintine belt and radiator hoses on diesel engines? Last year I replaced all heater hoses & tank radiator hoses. Autos are generally 5 years.

Usually there is no set replacement interval for most soft parts. Regular inspection and knowing what to look for is the key to minimize unexpected roadside issues, but, not a cure all.
From experience, belts and hoses rarely fail without notice, but, it does happen. Usually belts will crack, glaze over, harden, fray, squeal, crackle, slip, come off, need tension adjustment, etc. before they give up. If any combination of the above happens, its time for further investigation. Hoses usually bulge, harden, leak, crack (often from the inside first), etc. Generally, higher heat causes failure before colder hoses, but not always. Using the incorrect coolant can lead to early failures. Bad motor mounts can also lead to premature failures.
Bearings in tensioners, pumps, usually start singing/grinding/vibrating before failure. Misalignment should always catch your attention.
Segmented belts, its best to replace them at or before the recommended time/mileage interval if there is one. When replacing segmented belts, its wise to replace any related tensioners, water pumps, leaky seals etc. at the same time.
