Good morning, my name is Nick.Can I please start off with some brief questions. What is the year, chassis and application of the truck? Does the noise occur in those scenarios when it's cold or only at operating temperature? Have you noticed whether the engine fan is on, or off when the noise occurs? Does the Truck take Def Fluid?Thank you,ThankThank you,
