Gates 19446 HVAC Heater Hose - Heater To Connector

Gates Molded Heater Hose 19446

Gates 19446 is a molded HVAC heater hose built for tight engine bays where a factory-shaped coolant line is needed. This OE-style hose uses EPDM construction and a small 0.62 in. inside diameter at both ends for a precise routing path in the cooling system.

Compatible with 2002-2005 Dodge Ram 1500 and 2002-2005 Dodge Ram 2500 heater-to-connector applications, this molded heater hose supports coolant, water, and air transfer. It is also approved for marine use, making it a versatile replacement for demanding fluid-routing jobs.

Key Features

• Gates Molded Heater Hose line for OE-style fit and routing
• Part number 19446 for direct reference and ordering
• EPDM material for coolant-system service
• Factory-molded shape for smaller, tighter engine compartments

Product Details

The Gates Molded Heater Hose line is built around factory-molded shapes that follow the original hose path more closely than universal straight hose. For Dodge Ram 1500 and Dodge Ram 2500 trucks, Gates 19446 provides the molded routing needed at the heater-to-connector position while maintaining the correct small I.D. dimensions for the application. This part cross-references Four Seasons 19446 for the same application.

Common Problems This Hose Can Address

• Cracked or leaking heater hose at the molded section
• Incorrect hose routing in a tight engine compartment
• Restricted coolant flow from a deteriorated hose
• Softening, swelling, or age-related EPDM hose wear
• Replacement needs for heater-to-connector hose service on Ram trucks

Installation Notes and Tips

Verify the hose path, end diameters, and centerline length before installation. Match the molded shape to the original routing on the vehicle and inspect adjoining connectors, clamps, and nearby hoses for wear before reassembly. For best results, confirm fitment for 2002-2005 Dodge Ram 1500 or 2002-2005 Dodge Ram 2500 heater-to-connector applications before ordering Gates 19446.

Quality Assurance

Gates supplies molded coolant hose products in OE-style configurations for service replacement use. Part number 19446 is built to the listed dimensions and application details for the specified Dodge Ram fitments.
