Default sudden clunking from engine compartment

I was driving home tonight, about 15 miles or so,.. drove fine to and from, but about 6 blocks from town (thanks for that) I slowed to stop at a stop sign, and as soon as the truck stopped completely, A random loud clunking started from the wheel well. It sounded like something had gotten caught inside the wheel and was clunking against the wheel well, except the truck was not moving. As I listened further, it sounded like something was caught in the serpentine belt and was just clunking around in there. I thought maybe some debri had been thrown up in there, but I drove home, and it did it the whole way. I put it in park and it still did it. Shut it off, turned it back on, it still did it. Since it is dark out, and I have no under hood light, I couldn't really see anything. I didn't see that anything was wrong with the gauges, nor did any lights come on. I listened to it run for a short time, and with the hood up, it sounded like ice cracking or something popping when it gets too hot, but the temperature gauge did not change. I am hoping somebody has had this issue, or an idea of what it might be. Not too many mechanics in this small town, so I am kinda on my own. Thanks ahead of time for any help you can give me.

Default Re: sudden clunking from engine compartment

i replaced both this summer. when i was looking at the engine in the dark, it seemed that there was more than one type of sound. there seemed to be two different clacks coming from the central area of the engine,.. round the belt and fan, and one other slightly higher pitched sound coming from the drivers side of the engine. the clanks are random, like fireplace wood crackling, not rhythmic. when i was first driving it back, although it was a very short ride, it seemed that the noise got louder and more frequent the more i accellerated, and vice versa. does that make sense? thanks for your help, guys. really appreciate it.

perhaps your belt is ripped in some place and smacking against something

Now that it is light out, I went and checked the belt, as you suggested, and BINGO, YOUR'E A GENIUS. that's it. I can replace that myself, even better. Does this tearing along the front edge indicate an alignment problem with the pulleys, or does this happen on occasion, without any other underlying issues.
thanks a bunch, guys. you're lifesavers.

When you put on the new belt look close at all of the pulleys. There might be an issue with it rubbing or catching on one of them.

One of my rangers had a bad tensioner and it made the belt try to ride off the pullys. Make sure the tensioner looks square with the belt.

make sure all pulleys are tight and line up with eachother and hat there are no sharp edges, its not unusual for a belt to rip just from wear and tear, but just be safe and check everything

I took your advice and checked out the pulleys for alignment, etc. I have a friend that knows considerably more than I, also have a look at it, and it appears that everything is a go, so I put the new belt on, and my sweet little girl is back on the road and working a good usual. you guys are AWESOME!!! THANKS SO MUCH!
