The Audi engine coolant overflow hose adapter connects the overflow line from the expansion tank to the rest of the cooling system. This small yet essential component directs excess coolant back into circulation or into a recovery system. A cracked or failing adapter can cause coolant leaks or reduced system efficiency. Replacing it ensures the overflow system works properly and maintains coolant levels during thermal expansion.
Coolant adapters regulate overflow flow and help maintain proper coolant pressure. A high-quality adapter ensures smooth coolant redirection and prevents spillage or pressure loss.
Designed to handle coolant flow and pressure, these adapters are made from high-grade plastic or metal and shaped to fit snugly into OEM coolant systems.
