The Gates emission control hose for 2003–2009 Volvo S60 with the 2.5L five‑cylinder links the oil separator to the upper engine connection. This replacement restores the ventilation path between the separator and engine, addressing deterioration or leaks in the original hose to maintain proper crankcase venting and support the vehicle’s emissions plumbing.
