Gates 19627 HVAC Heater Hose

Gates Molded Heater Hose 19627

The Gates 19627 molded heater hose is an OEM-style coolant hose built for tight engine compartments where a straight hose will not route correctly. With a 19 mm (0.75 in) inside diameter at both ends and a molded 20.4 in (518 mm) centerline length, it supports heater and coolant routing on select Chevrolet Aveo, Aveo5, Pontiac G3, and Suzuki Swift+ applications.

Product Details

Gates Molded Heater Hose 19627 is built to follow the original hose path in vehicles with limited clearance around the engine, heater core, and thermostat connections. The molded profile helps maintain proper routing where a universal hose would be difficult to position. This hose is listed for heater-to-thermostat and engine-to-heater locations on 2009-2011 Chevrolet Aveo and Aveo5, 2009-2010 Pontiac G3, and 2009 Suzuki Swift+, along with additional older Astro, Safari, Storm, and Stylus heater hose applications. If you are replacing a worn heater hose on a Chevrolet Aveo or Pontiac G3, this Gates 19627 hose matches the OE-style molded layout needed for the job.

This part cross-references BBB Industries 11627 for the same application.

Common Uses

• Replacing a cracked or softened heater hose on a Chevrolet Aveo or Aveo5
• Restoring coolant flow between the heater circuit and thermostat housing
• Correcting hose routing in tight engine compartments
• Addressing coolant seepage at a molded hose section
• Replacing an aged heater hose on Pontiac G3 or Suzuki Swift+ models

Installation Notes

Verify hose routing, end diameters, and centerline length before installation. Compare the molded shape to the original hose removed from the vehicle to confirm the correct orientation for heater-to-thermostat or engine-to-heater placement. Inspect adjoining clamps, pipes, and fittings for corrosion or wear before installing the new hose. For best results, fill and bleed the cooling system according to the vehicle service procedure after installation.

Quality Assurance

Gates manufactures this hose as a molded EPDM replacement in an OE-style configuration for coolant and heater service. The design supports factory-style fitment on listed applications and is also approved for marine use.
