Hello there,
I bought this bentley 8 months ago and it always had this belt noise like it does this once and for 3 weeks it doesn't, it just chirps.
I learned that the belt and tensioner were replaced 2 years ago at the dealership.
I went back to the dealer to see what is wrong, the dealer said it was the water pump and they replaced it and it costed me $1,500 incl labor.
The next day same sound.
I am going crazy what could it be?

 

What year, model and engine (8 or 12 cyl)?

 

2011 continental flying spur speed w12

 

Do a water test on the belt.
