How to apply belt dressing.

Every now and then my belt squeels if I let it drop to idle like for turning a corner so I give it a squirt of belt dressing. Well, I had to do it again a few days ago, I made sure and sprayed it real good too.

Then today I noticed that at about 2500-3000 rpm I get a slight whining noise, the pitch increases as I rev it. The belt is very sticky too.

So could the belt dressing be sticking the belt to the pulleys causing a vibration?

Ok the dressing must have been it. I went out and sprayed soap on one side of the belt and it instantly quieted down, a minute or two later I sprayed the other side and it was almost silent.

One thing that bugs me, the t-belt slaps at certain rpms, I can watch it just below the tensioner pulley.

Seems like I either have it too tight and wreck the IP bearings or it's too loose and slaps like that. I had to tighten it up shortly after installing it a while back too. It's so loud I can hear it from inside.

That's one of the tests I use to see if the belt is tight enough.
 Just enough so it doesn't flop close to the timing belt cover,
 at about 2500 RPM.

Oh yeah, good idea.

tighten 'er up a lil' bit. You'll be fine
