Detailed Description

Gates EMH274 is an emission control hose made for crankcase ventilation applications where a direct OE-style replacement is needed. Its molded rubber-and-steel construction is built to match the original routing and connection style, helping maintain a secure seal between the PCV valve and intake. This part number, EMH274, is listed as OE Exact and is intended for vehicles that use a push-in hose connection in the crankcase ventilation system.

Compatible With 2009-2012 Ford Escape, PCV Valve To Intake; 2010-2012 Ford Fusion, PCV Valve To Intake; and 2009-2011 Mercury Mariner, PCV Valve To Intake. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Fix

• Cracked or hardened crankcase breather hose
• Vacuum leaks at the PCV-to-intake connection
• Loose or damaged push-in hose ends
• Emission system flow issues caused by hose deterioration
• Rough idle or drivability concerns related to ventilation leaks

Installation Notes and Tips

Verify the hose routing, end style, and dimensions before installation. The EMH274 uses push-in ends and is molded to follow the original path, so correct alignment at the PCV valve and intake connection is important. Inspect nearby fittings and mating surfaces for wear or contamination before installing the replacement hose.
