Product Details

Gates 19004 is a molded heater hose designed to follow the original hose path in vehicles with limited clearance. The formed shape helps maintain proper routing between the heater circuit and engine-side pipe connections, which is important for Chrysler Aspen, Dodge Durango, Jeep TJ, Jeep Wrangler, and Toyota Pickup applications listed below. This hose is also suitable for marine use, adding flexibility for service in multiple cooling-system environments. This part cross-references BBB Industries 11004 and Carlson 19004 for the same application.

Installation Notes and Quality

Verify end diameters, centerline length, and routing before installation to confirm the hose matches the original path. Check clamp condition, pipe surfaces, and adjacent components for wear before placing the hose into service.
