Well, it's been an interesting spring/summer since I had replaced mainly the entire cooling system parts. From the time after the change till now, I had to deal with a constant belt chirp.
During the summer though, the chirp went away due to temps above 85. I figured that the belt had to adjust to fit and conform.
Well, in the past two weeks as temps dropped below 50 and on a long trip, the squealing of the belt was like a runt of a pig. It turned everyone's head on the street and in vehicles that had the windows up.
Never buy Dayco Poly Rib belts for a Dodge Ram Van with the Magnum engines. My belt Dayco p/n was 5071005. Got it at the Advanced Auto online with a discount.
What squealed wasn't the seven V-grooves side of the belt. Oh no, that isn't the case. BUT, the other side of the belt that is shiny, slick and even with the proper belt tension allows the back side of the belt to slip causing the squeal over the water-pump pulley.
Now, a person here in the forums recommended a Gatorback belt by Goodyear. Can't find the posting, but a THANK YOU to them. That belt is mega quiet, not even a noise. Best of all, RockAuto had an inventory closeout sale with the belt 65% off this past week. Upon putting the belt on in 40 degree weather, starting the engine, I could have peace again. No loud squealing pig! haha
I tried all of the belt dressings, friction lubes, and even the Irish-Spring soap trick on that Dayco belt. It would work for about a day before the squealing pig came back.
So, if your belt tends to squeal, get a Goodyear Gatorback belt. For my 2001 magnum 5.2L engine with AC, the p/n is 4071005 pack number is 7PK2555.

The Gatorback belts also have a cross-cut groove design which is self cleaning and also works to eject water just like the sipes on tires. I run Gatorback belts on all my vehicles foreign & domestic and could not be happier. I might have been the one to recommend this , don't rightly remember.
This is an older post but wanted to give my vote to the Gatorback.
Back in 2001 I had to have the water pump replaced on a long vacation road trip. The garage put on a gatorback belt.
This past summer, 2014, I replaced the water pump and the local shop only had a Gates belt. I had no problems for the first 2,000 miles -- then each morning there was a "chirp" for about 2 minutes when you first started the van. Then progressively the time for the chirp to go away got longer and longer. After approximately 3,000 miles, the chirp turned into a constant squeal.
I had kept the Gatorback belt to put in my highway emergency kit. I put the 13 year old Gatorback belt back on the van to see if it would solve the squeal. It was complete silence.
Just ordered a new Gatorback belt for less than $18 with shipping. The quality of this belt is unsurpassed.

belt squeak --
Well I have an interesting story...
So I thought my tensioner was bad - so I replaced it because I heard a squeak in the belt there...and it was vibrating like the spring was bad
Then I replaced the tensioner - it still squeaked.
Then I started to think, maybe the alternator bearing is going bad???
Used the stethoscope - couldn't really hear the bearing squeaking...
My belt always squeaked in the morning, and then would chirp most of the day.
Then I sat there one day and watch the belt going round and round...I realized that the tensioner was moving - and it wasn't the spring -- it was the mount for the tensioner. It looked JUST like the tensioner spring moving -- but it wasn't.
So I took a chance and ordered from a junkyard a new tensioner mounting bracket...
On the back of the tensioner is a tab that goes into a hole on the mounting bracket. I took off my old one and tried to measure that hole compared to the junkyard part. The hole was maybe 1/2 of a millimeter bigger on my existing mount. I though, can this be enough to make the belt squeak? I also did have a vibration that seemed like my IAC was just a tiny bit clogged...but wasn't thinking about that issue at the time...
I installed the junkyard tensioner mount and then the tensioner. Turned the van on and viola! No belt squeak...also no engine vibration...also no more unusual engine noise...wow my engine is now running as smooth as any new 6 or 8 cylinder motor...
Just a story and maybe some info you can use in the future
