I just changed the timing belt on my 91 se and i think it is whining. could that be cause it is to tight or just cause its a new belt? Im not sure if i should drive it to much because of the whining... someone help me...

did you remember to put the timing plate back on before you reinstalled the crank pulleys. if not, the belt is more than likely running off the front side of the sprockets and rubbing on the shroud. Also, if the deflection is less than a half inch, the belt will make a whinning noise. My thoughts are that it is a little better tight than loose. the belt will stretch over time and the noise should diminish. a loose belt will make a slapping noise as the tension is removed during accelleration.

Ya thats what i was wondering and i just read about the deflection on the top of the belt so i took it all apart again and adjusted the tensioner.

Did the noise go away after you adjusted the tensioner?

he did say SE.....wouldn't it be a chain instead of a belt????...or did 89-91's use belts?

yes 89-91 SE used the VG so yes it had a belt.

Yes after i adjusted it the noise went away. It was way to tight and only had around a quarter inch deflection. do you think that did any damage to the new belt? it didnt really look work but what do i know.

tighter is better and according to one ASE nissan tech, the whinning noise is no big deal. just means the belt is a tad tight.

Ok Thankyou for your help, now i dont have to worry about it anymore

I read on this site that it is bad to overtighten for possible risk of breaking the crankshaft.
