Where is the whine?
My 95 YJ developed a whine. It sounds like it is coming from the front of the engine. Everything that is run by the serpentine belt has been replaced and the timing gears, chain and tensioner have been replaced. New water pump too. The whine starts after the engine has run for a while, the engine has to be warm. The whine is more pronounced at a steady engine speed, it decreases when accelerating and increases when decelerating. This seems to get louder with lower outside temperatures. It makes no difference if the clutch is engaged or disengaged, air conditioning on or off, turning the steering wheel makes no difference. The whine does go away after 5-10 minutes of driving after it starts.
Any ideas are appreciated.
