My 2002 Ford Escape has started making an intermittent high pitch squealing noise when demanding more power from the engine by pressing the gas pedal. The noise goes away if I remove my foot from the gas pedal. The noise usually start after 5 minutes from starting and driving the vehicle. Usually when going up a hill with engine running at 2-3000 rpm in town. This is also happens when driving on highway 65-70 mph and going up a slight hill. The noise is more noticeable with temperature is below freezing. I cannot replicate the noise when the car is in my garage even is I rev the engine to 4 or 5,000 rpm.
What is the cause of this noise? How can I fix it?
I have already performed the following easy preventive maintenance tasks and the noise did not go away. This includes the following:
1. Installed a new serpentine belt and tensioner
2. Installed a new water pump belt
3. Installed a new fuel filter.
have the same problem?
