Mercedes Vacuum Hose - Cohline 1179970982

Product Information

A Vacuum Hose is a flexible rubber or plastic tube in a vehicle that carries vacuum (negative air pressure) from the intake manifold or vacuum pump to various engine components. Many automotive systems rely on engine vacuum for proper operation, including the brake booster, emissions controls, fuel pressure regulator, and HVAC controls.

• Rough idle or stalling – unmetered air entering the engine disrupts the fuel-air mixture.
• Hissing noise under the hood – sound of air leaking from a broken or loose hose.
• Poor acceleration / loss of power – incorrect air-fuel ratio affects combustion.
• Check Engine Light (CEL) – often triggered by lean condition codes (P0171, P0174).
