How to replace an alternator on a 2015 Kenworth T680 (PACCAR MX-13 motor)

my truck stopped running this morning around 3 AM while it was -19°F in Minnesota, due to loss of voltage. after 4-5 hours of enduring the cold i was able to get a new alternator. voltage is back up and truck is running. heat feels GOOD!

I will suggest you should replace the serpentine belts too and check batteries too, good jobs brother thanks,

[@justanotherotrguy]

The belts were in great condition and I replaced the batteries shortly after. Replaced them this year too lol thanks for watching, hope you stick around!!

Great video, How manny miles does that alternator last?

[@justanotherotrguy]

A lot lol I think the alternator I replaced had multiple hundred thousand miles on it. I think it was the original factory alternator

Question how did you know it was the alternator ? And not the starter ? Great video I have not done it but feel I can now

[@justanotherotrguy]

The batteries will die while the truck is running for sure if the alternator dies. Its job is to charge them and without it your batteries will go out on you. You can also test the voltage on it when you start the truck. you should have at least 12v on the positive terminal, if you dont its probably dead or dying
