Got a new sound comming from my engine. I'm not entierly sure what it is. I know that the belt tensioner is getting weak, and that is what it could most likely be. I'm just not 100% sure. And if it is, I'm not sure on how to replace the two? tensioners as my bentely manual doesn't exactly mention how to.
The sound is high pitched, mainly when the engine is cold. It fluctuates as the RPM's change. Even when the engine is warmed up, while on the highway, crusing at 70mph, I can still hear this high pitched squeal (Heating is turned off). When I opened the window, while at slow speeds, the sound is REALLY loud. When crusing, it tends to fad away, then as I gently tap the accelerator, the sound spikes.
Curious thing though. I had driven 20 mi with that sound today until i got to a gas station. Turned off the engine while was being refueled, started her up once done and the sound was gone.
It's been occuring for the past 2 days now.
