Key Features

• Factory-molded design for accurate routing in compact engine bays
• EPDM construction for heater and coolant service
• Small I.D. hose with 0.72 in. / 18 mm end inside diameter
• 7.5 in. centerline length for the specified application
• OEM-style replacement for HVAC heater hose routing
• Part number 19736 for direct catalog lookup

Product Details

Gates Molded Heater Hose 19736 is built for vehicles that use a formed hose to connect heater and coolant passages without kinking or collapsing around nearby components. The molded profile helps maintain the intended flow path in tighter engine compartments, making it a practical replacement for HVAC heater hose service on applications such as Chrysler 300, Dodge Charger, Dodge Magnum, Saturn Vue, and Ford Windstar. This hose is also listed for select Chevrolet Cavalier, Pontiac Sunfire, Nissan Altima, and related routing positions where a formed coolant hose is required. Part number 19736 is a useful reference when matching the correct molded shape and dimensions.

This Gates molded heater hose line is intended for coolant, water, and air applications, with marine approval noted by the manufacturer. The EPDM material supports common underhood heating and cooling demands while the molded construction helps preserve fitment in confined spaces.

What It Helps Solve

• Cracked or leaking heater hose routing
• Kinked hose sections caused by tight bends
• Improper coolant flow through a formed HVAC hose path
• Replacement needs for molded heater-to-tee or tee-to-heater routing
• Service issues on vehicles using small I.D. formed coolant hose

Installation Notes and Tips

Verify the vehicle’s hose routing position before installation, since this part is listed for multiple locations including Heater To Tee, Heater To Tee-2, Tee-1 To Heater, Heater To Tee-1, Pipe-1 To Tee, Engine To Pipe-1 (Right), and Pipe-2 To Pipe-3. Confirm the end inside diameter and centerline length against the removed hose to ensure the molded shape matches the original routing. For fitment-specific searches, this part is commonly referenced for 2005-2008 Chrysler 300, 2006-2008 Dodge Charger, and 2008-2010 Saturn Vue heater hose applications.
