Loose Fittings and Worn Out Hoses

Another common cause of coolant leaks in the Audi S4 4.2 is loose fittings and worn-out hoses. Over time, the fittings and hoses that connect the engine to the radiator and water pump can become loose or worn out, causing coolant to leak. It is important to regularly inspect these parts and replace them as needed to prevent leaks.
