Product Details

This Gates molded coolant hose is shaped to match the original routing used on heater inlet connections, helping maintain proper hose alignment and clearance around nearby components. Part number 19529 is a direct-fit style replacement for 2009-2019 Toyota Corolla heater inlet, 2009-2014 Toyota Matrix heater inlet, and 2009-2010 Pontiac Vibe heater inlet applications.
