Whistling Noise problem
2000 Nissan Altima 4 cyl Front Wheel Drive Automatic 93000 miles
When the engine is warmed up, a whistling noise appears which I can hear near the alternator area. I already confirmed belts and pulleys are fine. After 1-2 minutes of whistling, I notice the RPMs drop very little and the rediator fans turn on. After 10-20 seconds of the fans being on, the whistling goes away and then the fans turn off. If I keep the engine running, the same operation happens over and over again like every 5 minutes. First the whistling starts, then after 1-2 minutes, the RPMs drop and the fans turn on. Then the whistling goes away and then the fans go off.
This is a very weird situation.
Thanks in advance for your suggestions/possible solutions.
have the same problem?
