Serpentine Belt Chirp/Squeal/Squeak Help!
Tried searching, but didn't come across another post that looked similar to what I'm experiencing...
I just replaced my waterpump, and I know have a squeal/squeak/chirp coming from the serpentine belt.
It's not very loud like a true fan belt squeal sound that you hear on poorly maintained vehicles. It's more high pitched, and seems to almost tick or chirp very quickly. The problem becomes most noticeable around 1400 rpm's.
You can hear the noise at idle, but you pretty much have to be listening for it. Under a bit of throttle, when it gets to that 1400 rpms, it is significantly louder - not earpiercing, but definitely noticeable.
Now, the belt appears new. I think it was replaced within the last 15k miles - it's still pliable, has no cracks, and looks to be in great shape.
The truck was NOT making this noise prior to replacing the water pump. I've checked under the hood and it looks like the belt is seeded properly around each pulley.
I also tried the soap trick, which made the sound disappear, but it came back about 10 miles later. I have NOT tried belt dressing, nor have I taken the belt off to check each pulley.
