Installation Notes and Tips

Verify the hose routing and connector-to-tee (left) location before installation. Compare the original hose length, inside diameter, and end style to EMH186 to confirm proper fit. Inspect nearby connectors and tees for wear, oil saturation, or cracking so the replacement hose can seal correctly. This Gates EMH186 hose uses push-in ends and does not include hardware or a protective sleeve.
