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.

I guess it all depends on whether you want to replace on side of road or at your convenience. Belts are rubber just like tires and they break down over time. The engine compartment is a pretty harsh environment so I would think 5 years to be a pretty good number... at least to do serious inspections. Serpentine belts are easier to inspect and when you see cracking on the groove side it indicates the rubber has lost it's flexibility. If you believe think 5 years is too often then you are probably one who don't mind replacing on side of road. Remember also that failure modes follow a bell curve shape. Few parts fail at the low side of the curve and a few fail at the high side of the curve... so there will alway's be someone who has a belt or hose that has made it 300,000 miles and 20 years :)
