Gates 19499 HVAC Heater Hose - Heater To Thermostat

Gates Molded Heater Hose 19499 Overview

The Gates 19499 molded heater hose is an OEM-style coolant hose built for tight engine bays where a formed routing path matters. It is made from EPDM and measures 21.4 inches (544 mm) centerline length with 16 mm (0.62 in) inside diameter at both ends.

Compatible With 2007-2012 Chevrolet Malibu heater to thermostat, 2007-2009 Pontiac G6 heater to thermostat, and 2007-2009 Saturn Aura heater to thermostat applications, this molded hose supports factory-style coolant routing in the HVAC system.

Key Features

Product Details

Gates Molded Heater Hose line products are built for applications that require a pre-formed hose rather than a straight universal length. The molded design helps match the original routing path between the heater circuit and thermostat area, which is especially important in smaller, tighter-fitting engine compartments. For buyers searching for a 2008 Chevrolet Malibu heater hose, 2009 Pontiac G6 heater to thermostat hose, or 2007 Saturn Aura molded coolant hose, part number 19499 provides a direct OE-style replacement option.

This part cross-references Dixie Electric Ltd 11499 for the same application.

Common Problems This Hose Can Address

• Cracked or leaking heater hose at the factory bend
• Collapsed hose sections caused by age and heat cycling
• Incorrect routing from using a non-molded replacement hose
• Coolant seepage at the heater-to-thermostat connection
• Restricted flow from a hose that no longer holds its formed shape

Installation Notes

Verify end diameters, centerline length, and routing before installation. Compare the existing hose path to the molded shape of Gates 19499 to confirm the heater-to-thermostat layout matches your vehicle. Inspect adjoining clamps, fittings, and nearby coolant components for wear or contamination before reassembly.

Quality Assurance

Gates is known for OE-style hose construction, and this molded heater hose is built to factory-style dimensions for the listed Chevrolet Malibu, Pontiac G6, and Saturn Aura applications. The EPDM material and molded form support consistent coolant-system routing in the intended fitments.
