fan belt tentioner
OK so yesterday I heard a loud POP sound while driving, then a few seconds later I started to get a very loud squealing sounds like a fan belt was slipping
then my voltage gauge and all gauges went bonkers, going from normal reading to max reading then to bottoming out all gauges, with my voltage readings going from full charging to none
when it was safe to pull over I did, and looked under the hood, everything was working to the eye
tried to feel for any vibrations in my alternator, as that was suspected issue, was told the popping sound I heard was maybe a with the alternator too, so my number one idea! source of troubles, it is 8 yrs old so?
But agan could not fel any thing wrong or see anything?
drive truck home, with squealing sunds going from none to super loud to none, at random, with it mostly stopping squealing when I let off the gas
got home again did a quick look under the hood, was now dark out and no garage and 2 degree's outside
this morning I get up, truck starts right up
check voltage at battery, 11.6 volts, so not charging , then notoce the belt is NOW not spinning at all, there is even about a 3/4's an inch of slack in it
zero tention on the belt
so while there is no resistance on the belt, I hand spun all pulleys, minus the big one at the bottom and they all spin freely and with no noticable wiggle to them, like bad bering
has anyone ever had a betl tensioner go bad, any one recommend a replacemnt one
and any tips on getting it off?
its a 2006 dodge ram 2500, hemi/gas motor
