Saab Vacuum Hose - Genuine Saab 7591936

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).

About Genuine Saab

The original parts used by Saab to build your car are available as replacement parts under the “Genuine Saab” brand. Manufactured under the direction of Saab, expect excellent quality and a premium price since these parts are exclusively available through the Saab Dealership network.

You may not realize this, but the parts that make up your Saab are not necessarily manufactured by Saab. No cause for concern, as Saab designs the part, hires a manufacturer, and ensures its quality to you. In fact, many of these manufacturers have been making parts for Saab for decades. In our industry these manufacturers are called OEM (Original Equipment Manufacturers), and these are often brands you recognize, including Lemforder, ZF, Sachs, Bosch, Valeo, Zimmermann, Siemens VDO, Corteco, and more. Don’t be surprised to open that Genuine Saab parts box and find an OEM branded part inside, simply with the addition of a Saab logo.

Be sure to keep an eye out for OE tags on our product pages to quickly identify parts coming direct from OE manufacturers. That extra bit of insight could save you some serious money while shopping! Refer to our OE Academy for further information regarding the OE/OEM tags throughout the site.
