Detailed Description

This Gates EMH073 hose is engineered for the valve cover to intake tube connection on the right side of the engine. It is a direct replacement for the original crankcase breather hose used in emission control service, helping maintain the intended flow path between the valve cover and intake tract. This part cross-references GM OE numbers 12638607 and 12670793 for the same application.

Compatible With 2014-2018 Chevrolet Silverado 1500, valve cover to intake tube (right); 2014-2018 GMC Sierra 1500, valve cover to intake tube (right); 2015-2020 Cadillac Escalade, valve cover to intake tube (right); and 2015-2020 Chevrolet Tahoe, valve cover to intake tube (right). It also fits 2015-2020 GMC Yukon and Yukon XL, plus 2019 Chevrolet Silverado 1500 LD and 2019 GMC Sierra 1500 Limited in the same right-side routing.

What It Helps Address

• Cracked or brittle crankcase breather hose
• Broken clip-on connection at the valve cover or intake tube
• Emission system leaks from a damaged hose path
• Improper crankcase ventilation routing after hose failure
• Check engine concerns related to hose integrity in the ventilation circuit

Installation Notes and Tips

Verify the hose routing, end style, and centerline length before installation. The EMH073 uses clip-on ends and molded shaping, so correct alignment at both connection points is important for a secure seal. Confirm the vehicle application by year, make, model, and right-side valve cover to intake tube position before ordering.

Quality Assurance

Gates manufactures this emission control hose as an OE-exact replacement built from durable materials for service life in crankcase ventilation applications. The molded design and protective sleeve support proper fit and long-term use in the specified emission system routing.
