He lives in FL his winter is fall for most people unless he is traveling in the dead of winter up north he will probally never have a problem with it starting. Just my thinking. LOL

The time to replace them is when they go bad. There is a article in the maintenance section on how to test them. They are not maintenance items to be replaced every X amount of miles.

niether is a serpantine belt but if you wait till it fails, you will be on the side of the road callin AA.
What do you consider good servoce life for a part that cost 10 bucks?
170k miles is good service life. If they are fine now, they won't give you trouble in the summer but come next winter, if your truck won't start, then your vehicle may be down at an innoportune time. I would do it before next winter just so i could not worry about it anymore. 3 of mine went out and this winter i had trouble starting it the first cold front that rolled through. I had no choice but to cancel my saturday plans and do it. I would have rather done it one lazy weekend last Aug. when i wasn't pushed to do it.
I thought mine would have lasted longer than 104k miles but they didn't.
I plan to replace a few more parts (that aren't broken yet) this summer just for piece of mind.

thanks chenry i will prolly replace them in july or aug just to be safe i saw a brand new set of motocraft on ebay sell for $60 shipped. sounds cheap. does it take long to replace them... any special tools?

[cliford]

no special tools needed and i did my in 3 hours i think. i would definitely change them before they fail. mine failed at college. $150 i got it home so i could change them. it was either that or change them in 10 degrees.
