i *just* got off the phone with my local mechanic- had the truck in for an O2 sensor that went out.
he mentioned that my 01 only has 44k miles, but it's at the recommended 8 year time interval for the timing belt. they quoted me just under $1000 to replace the timing belt, water pump, serpentine belt, but i'll have to ask them when i pick it up tonight if that includes tensioners too-- i had to check here to see what else was all needed
i know these guys are a little bit on the high side, but i trust them, so...*shrug*
