well, at 91,206 miles i finally bit the bullet before my timing belt snapped. i dropped it off this morning for a new timing belt, water pump and a new serpentine belt. thank god it didnt snap before! the sevice tech said the replacement belt is made by gates. as soon as i get the car back its going over to the tire shop for an alignment and a new set of tires being as how i'm almost on slicks. i'm putting on bf goodrich traction t/a's all season. i will post a pic of the timing belt as soon as i get it back from my chevy dealership. it was more expensive to have the work done there, but they warranty it for 12 months/12000miles. cost is $698.00 u.s. i posted pics of the used parts in the photography section.
