Ever since i got my car, b16 crx hf, the alternator seems to be pretty noisey. Its not noisy like the belt is loose, it makes just regular noise that other b16'ed vehicles dont. Its noisey. Its whiiizzzzzing. Does anyone know what im talking about.

It just now got pretty loose, I tightend it to the right tension, and its whizzing even worse now, in high RPM


Can anyone help me?

sounds like your actually turboed. anyway get some belt dressing on there see if that quiets it down. also alternator winds could be corroded and grinding on the houseing

 

My alternator did the same thing, kinda sounded like a SC. After I swap motors I tried turning the old alt pully and I couldnt spin it by hand.

 

so what should i do?

 

what is belt dressing?

 

could be a bad bearing. take it off and take it to autozone and get it tested. if it makes noise on the test bench then you might need to replace the alternator.

Belt dressing is just some **** you spray on your belts, keeps them from slipping and stops the sqweaking, its like armorall for your belts I guess. Take off your alternator belt and try turning the alt by hand, if it turns freely put the belt back on start the car and take off the positive battery cable and if the car dosent die then I wouldnt worry about it.

 

mine does the same thing. i am going to take a look at it today and see if i can spin it by hand.

 

Mine was doing the exact same thing. The bearings in the alternator are toast. You can either have it rebuilt ($40-$50) or buy another one. I got a 90 Integra LS alternator for $30, problem solved.

 

Thanks man, and everyone else who helped. Does the LS alternator bolt right up? Any modifications needed? Thanks again.

 

Yep, bolts and plugs right up. It was a tight fit with a 4th gen though. I had to unbolt my fuel rail to get the old one out and put the new one in. Other than that, no problems.
