Product Details

Gates Molded Heater Hose 19843 is built to match the routing needs of modern engine compartments where straight hose sections do not follow the original path. Its molded profile helps maintain the correct hose shape between the heater circuit and pipe connection, while the EPDM material is suited for heat and coolant exposure.

This part cross-references Monroe Shocks & Struts (e.g., 11843, 16416M) for the same application.

What It Helps Address

• Cracked or heat-aged heater hose sections
• Coolant seepage at a molded hose run
• Incorrect hose routing in tight engine compartments
• Loss of heater circuit flow from a deteriorated hose
• Fitment issues when a straight hose does not match the factory path

Installation Notes and Tips

Verify the hose routing, end diameters, and centerline length before installation. Confirm the heater-to-pipe position on the vehicle and compare the molded shape to the original hose path. Inspect adjoining pipes, clamps, and connection points for wear or corrosion before installing the new hose. For Chrysler 300, Dodge Charger, and Dodge Magnum applications, match the hose to the factory routing to maintain proper clearance.
