How much labor to replace 2004 corolla serpentine belt? Thank you. aln2007

If you look at the estimator at this website it says 85-105 dollars in my neck of the woods. Seems quite high so I can assume that some component may have to be removed for clearance. It would help if you gave what estimate you got from some shop to do the work instead of you holding back information. On this site you get more help if you share all that you know about what your concern is. We techs typically back off from helping if information is withheld. Did you get an estimate and what is it?

Not much, loosen 1 bolt on tension pulley. Release tension on pulley and slide off belt. Belt slides off much easier then it goes on. Make a diagram of belt pattern BEFORE you remove it.
