Detailed Product Overview

URO 5955919 is an engine crankcase breather hose for the Saab 9-5 crankcase ventilation system. The molded EPDM body is selected for durability in an engine bay environment where heat and oil vapor can cause standard rubber hoses to crack, split, or collapse. With end inside diameters of 0.43 in. and 0.69 in., this hose is built to match the specified connection sizes and restore the breather path to the oil trap.

For 2004-2009 Saab 9-5 4-cylinder models, this breather hose helps return the crankcase ventilation system to proper operation. Part number 5955919 is also referenced as 59 55 919 and URO-003447 for the same application.

Common Problems This Hose Can Address

• Cracked or split crankcase breather hose
• Restricted crankcase ventilation flow
• Oil vapor leakage around the breather circuit
• Improper hydrocarbon emission control from a failed hose
• Vacuum-related drivability issues caused by a deteriorated ventilation hose

Installation Notes and Tips

Verify the vehicle is a 2004-2009 Saab 9-5 4-cylinder model with the hose routed to the oil trap before ordering. Inspect the surrounding crankcase ventilation components, hose connectors, and mating ports for oil residue, hardening, or damage before installation. Confirm the molded shape and connector diameters match the original hose path so the breather system seals correctly.

Quality Assurance

URO backs this hose with a 24-month unlimited mileage warranty. The replacement is intended to restore failed OE breather hose function using materials chosen to resist cracking and splitting from engine heat and oil vapor.
