Gates 19813 Molded Heater Hose Overview

The Gates 19813 molded heater hose is an OEM-style coolant hose built for tight engine compartments where a formed routing path matters. It is made from EPDM and is sized with 19 mm (0.73 in) inside diameters at both ends, with a 35.5 in (902 mm) centerline length.

Compatible with 2000-2001 Nissan Maxima heater-to-pipe-1 applications, this molded heater hose follows the factory-style shape needed for proper routing in compact HVAC and cooling system layouts. The Gates Molded Heater Hose line focuses on formed replacement hoses for modern engine bays, and this part cross-references BBB Industries 11813 for the same application.

Installation Notes and Tips
