Hey everyone I just recently replaced my fan clutch. When the fan started sounding like a jet engine I also noticed another noise that initally sounded like it was coming from inside the rear part of the car. After I rolled down the windows and listened to it, it sounds like it's coming from under the car. I only hear the noise when I'm accelerating in gear. The noise changes tones and frequencies while I'm driving, it's quite wierd. After I got the fan clutch replaced I figured the noise would go away but it did NOT. Has anyone else experienced a noise which I can best describe as a whining one, but again the noise changes periodically. It doesn't sound like it's coming from the engine, it sounds like it's in the muffler almost. Thanks!
