Quick/Simple Question

I can't remember the size but all you do is take the bolts out. I want to say it was like a 12, 13, or 14mm ... been a while. You don't have to worry about any tension issues (when your belt is off there is not tension on the pulley to snap back) if that makes sense. I assume you probably know that but thought I'd clarify incase you didn't.

If you don't have any deep sockets I'd put on some gloves first because you will most likely bust some knuckles using wrenches. Get a bar or something sturdy that will fit over the end of the wrench to break them loose if you can't by hand.

Did you change both of them? The idler pulley connected to the tensioner sounds like the one you changed (more difficult than the other pulley to change but not really difficult). Reason I ask is because I changed out only one of mine and the other one started that damn sqealing so I replaced it and no more issues. FWIW, the pulley is the same part as the one you replaced .. I'm talking about the pulley above it in case my post is confusing

Get under the car and use a stick, dowel, or broom handle and push on the tensioner - i have to do it that way with the blower.
