The idler pulley I bought didn't come with a new bearing, do I reuse the old one? Or where do I get a new one?
Today I successfully installed a new third brake light in the spoiler and the new trunk lifts. (remember this is great for a beginner! and a girl...)

 

You're talking about one for the air conditioner belt, right?

Wow the whole reason to buy an idler pulley is usually to get a new bearing. The bearing is a standard #6203. Don't use the old one as a new one costs only a few dollars and is widely available.

 

Yes the ac. I got it from rock auto and it did not come with the bearing, do I get one at any auto parts store or is it a special one?

 

Nothing special about it, just a generic 6203 double sealed ball bearing.

 

Mk, you never cease to amaze me. Where do you get this information? I know you are a very private person who is unlikely to reply, but I'd sure like to get a copy of your cerebral hard drive.

 

ok it wasn't the bearing it was missing the bushing. Can I just reuse the old one?

 

Yes the washers and spacers on the bolt would be reusable, they don't wear out.
