Gates 12442 HVAC Heater Hose - Reservoir To Filler Neck

Gates Molded Heater Hose 12442 Overview

Gates 12442 is a molded coolant hose built for tight engine bays where a straight hose will not route cleanly. It uses EPDM construction and an OEM-style molded shape to support coolant, water, and air transfer in the reservoir-to-filler-neck position.

Compatible With 2007-2012 Nissan Altima reservoir to filler neck applications, this molded heater hose follows the factory routing used in compact engine compartments. The Gates Molded Heater Hose line focuses on OE-style fit and formed bends for service replacement on vehicles like the Nissan Altima.
