The outer diameter of 6 mm and a center-to-center length of approximately 358 mm allow for precise installation within tight engine spaces. Its durable steel construction withstands harsh operating conditions, including vibration, heat, and exposure to coolant chemicals. Properly functioning return lines like this are vital for preventing coolant loss and maintaining consistent engine temperature.
