Hi, Got a 2000 Dodge Caravan 3.0L with just over 100,000 miles. Just got it in June so all I know is that it was faithfully garaged kept and truly driven by a nice older lady whom doesn’t drive anymore (one owner).
Since I drive with the radio on, I am not sure when the squealing started. Am pretty sure it is belt-related, but not 100%. And it is loud enough that I’ll hear it, even with the radio on, but not necessarily at highway speeds.
Not sure if power drops while squealing but that may be a completely different issue, but in any case at times while accelerating, it seems like the power fades and then picks up - but then, I am now in the habit of backing off the accelerator as soon as I hear a squeal.
It squeals anywhere from 2-10 seconds at a time, anywhere from 2x a minute to once every 5-10 minutes. It squeals much more when driving, does not really squeal when idling.
I see the method of squirting water at the ribbed side of the belt to see if it squeals more/louder or less. Since the squeal is only occasional and only for a bit if I rev the engine then squirt - the water doesn’t seem to make any difference.
So I have a few questions
What are all the pulleys on the belts? I know the small belt in the front is the A/C, with an idler. I know one pulley on the larger belt would be the crankshaft (?), then there is the alternator, an idler, the tensioner - anything else?
What’s a good approach to find what’s wrong?
