URO 9146489 Engine Crankcase Breather Hose

Volvo 850 Crankcase Breather Hose

This URO engine crankcase breather hose restores crankcase ventilation flow when the original hose has cracked, split, or hardened from heat and oil vapor. It is a direct-fit replacement for Volvo 850 applications and supports proper hydrocarbon emission control.

Key Features

• EPDM construction resists engine heat and oil vapor exposure
• Black molded hose with one branch and two hose connectors
• Direct replacement for failed OE crankcase breather hose routing
• Guaranteed fitment for listed Volvo 850 applications
• URO 9146489 replacement part for emission control service

Detailed Description

URO 9146489 is an engine crankcase breather hose for the emission control and crankcase ventilation system. Built from EPDM and formed as a molded black hose, it is made to replace the original hose on Volvo 850 models where the breather line runs from the flame trap pipe to the oil separator. This hose helps restore the crankcase ventilation path needed for proper hydrocarbon emissions control and stable engine breathing. It is a practical OE-style replacement for 1993-1997 Volvo 850 and 1994-1997 Volvo 850 vehicles, including applications noted to engine 330413.

This part cross-references 147 53028 738 and 32312151 for the same application.

What It Helps Fix

• Cracked or split crankcase breather hose
• Oil vapor leaks at the breather line
• Restricted crankcase ventilation flow
• Emission control issues related to failed breather plumbing
• Hose deterioration from engine heat exposure

Installation Notes and Tips

Verify the hose routing against the original part before installation. This hose is listed for Volvo 850 models with the noted flame trap pipe to oil separator configuration, so confirm the engine and breather layout match your vehicle. Inspect adjacent ventilation components for buildup, brittleness, or damage before installing the replacement hose.

Quality Assurance

URO 9146489 includes a 24-month unlimited mileage warranty. The replacement hose uses high-quality EPDM material to help resist cracking and splitting in demanding under-hood conditions.
