How do I replace the serpentine belt? Are there sensors on the rear brakes?
I think its to old to have sensors on the rear brakes, but if you look at the hubs on the axle side and see wires coming out then yes you have a sensor, the serpintine belt has a wheel that doesnt run anything ( like the altenator or water pump) you put a socket or wrench on the bolt of that wheel and u can relieve the tension that way and replace the belt. im in little chute and can stop by and show you if u need help

When you open the hood there is a diagram on a sticker that shows exactly how to do this. Should be on the front lip or the side of the engine compartment. You have to make sure you get it lined back up right and remember to check it once the engine has been started and make sure it running on all the pulleys correctly.
Here is a good diagram that should be able to help in case your sticker was damaged or removed. Good luck!

it is on a sticker adhered to your radiator shroud.
if it is removed, damaged, or unclear...
one tip - if you look by the crankshaft pulley to the right you will see a tubular looking shaft about 1" diameter , you will notice you can't get the belt out from under this piece , it has a nut on it , once you take the nut off , you will notice it has a star shaped point on the tip of the stud , it requires a reverse torx socket or wrench to remove the stud , when you get the stud out the tube piece it can be removed , then the belt comes off , replace the belt , now comes the tricky part , fitting that tube spacer back into its spot , it can be difficult , once its in place put the stud back in , and put the nut on and tighten it.

Should be a diagram sticker in the engine compartment, either under the hood or around the top of the radiator.
