The Water Transfer Connection (WTC) is a component found that helps transfer water from one point to another. It is usually made up of metal or plastic and consists of two connection points with a tube in between. The WTC is responsible for connecting the engine cooling system to the radiator and heater core, allowing for the proper flow of coolant throughout the vehicle's system. Without a functioning WTC, overheating can occur which can lead to engine damage or failure. Therefore, it is important to ensure that this component is regularly inspected and replaced if necessary.
