It transports coolant to cool the VGT actuator, which is essential for proper turbo operation and engine performance. The hose measures 17 inches center-to-center and has 17mm banjo fittings on one end and 10mm banjo on the other. Replace this hose if you notice coolant leaks, cracks, or during major engine service to avoid overheating the VGT actuator and potential turbo damage.
