replace my thermostate. Now i have a sqeaking noise underneath the hood.

im not sure the thermostat was replaced by my ford dealer. it has been very cold weather and a lot of fog. I did go to the car wash and wash what I could with the hood propped open. I didn't dare to get the engine wet with the cold weather. it did quiet down to a little chirp. I thought maybe salt and dirt has got underneath the car and that's what could be causing it.

thank you im hoping that's all it is. dirt and salt. hope its not the belts. I plan on getting rid of it this year any ways. I need to up grade to a bigger vehicle. love the flex.
