What It Helps Fix

• Loose or poor-fitting replacement hose connections
• Restricted crankcase ventilation flow from aged rubber hoses

Installation Notes and Tips

Verify the hose routing before removal and compare the original length, diameter, and end style to the Gates EMH309. Inspect the valve cover and intake tube ports for damage or buildup before installing the new hose. This part is a direct-fit style replacement for the listed Nissan Murano and Nissan Quest applications, so proper alignment at both ends is important for a secure seal.
