so I'm driving home and my CEL comes on. Gauges appear normal, car is running fine, I continue home. I stop at a light and go to make aright hand turn when I notice she is severly underpowered. NO BOOST. I get her home, pop the hood and find a pulley busted. Well, more like exploded.
What pulley is this and where can I buy a replacement? What does this belt drive besides the */c?
Nope, you have 2 other smooth 3" pulleys, one is right next to the grooved one as the tensioner pulley, the other is just above and to the the right of the harmonic balancer. There also another smooth pulley used on the tensioner on the accessory belt.
The pulley you need to replace is the only grooved pulley on the car. It'* grooved to help align the belt on the longest run of the circuit for the belt; from the balancer to the idler itself.
