I changed the timing belt, tensioner, and drive belts 200 miles ago. It started with a chirp at startup. Now, pretty consitantly it'll squeal between 1500 and 2500 RPM. Then it just stops.
It's the embarrassing, obnoxious squeal and quite loud.

The tension on the drive belts seems reasonable.

I just checked it cold and it only chirped at startup but revved okay.
Last night when hot, it squealed like a stuck pig.

What is the common bone headed thing I did wrong?
