What would I be looking for as tell tell signs the timing belt is slipping on the WP pulley

I set my belt according to the Arnnworx tool and I could barely get it to turn with one hand. However the white text on the back of the belt is smeared a bit. There is no fraying of the belt.

I would think a bit of smearing would happen on some level but I'm not sure.

Run the motor with the belt cover off and watch it closely while revving it abruptly? I remember watching mine a few months ago that way.

One way to tell the belt is slipping on the pulley is if the water temp remains at the high limits, regardless of what the temp fan switches do to keep it cooler. If you feel the belt is tight and the paint shows a possible smear as an indicator of slippage, I don't think that's a strong indicator. Smearing can be caused during installation of the belts from oil on your hands, or the print on the belt being fairly delicate to start with.

Well I pulled the timing cover and ran the engine and I did not see any slippage. The back of the belt still had a texture and hadn't been "burnt" off by too much friction you would expect if it was getting hot by sliding over the pulley rather than turn it.

It didn't slip when I blipped the throttle either, so I think I'm good.
