Product Line Details

Gates Molded Coolant Hose parts are built for upper, lower, bypass, heater, and other coolant routing needs. This line focuses on OE-style dimensions and molded shapes so the replacement hose follows the original path without requiring a universal fit approach.

Detailed Description

This Gates 23522 radiator coolant hose is a molded lower hose for 2009-2019 Toyota Corolla, 2009-2014 Toyota Matrix, and 2009-2010 Pontiac Vibe. The EPDM material is suited for coolant exposure, while the molded profile and 14.3-inch centerline length help maintain the factory hose route in the engine bay. For buyers searching for a 2009-2019 Toyota Corolla lower radiator hose or a 2009-2014 Toyota Matrix coolant hose, this part number provides a direct replacement option. Gates 23522 also cross-references Bosch 66205 for the same application.

What It Helps Address

• Cracked or split lower radiator hose
• Coolant leaks at the hose body
• Incorrect hose routing from a worn replacement part
• Softening or deterioration from age and heat cycling
• Fitment issues caused by non-molded universal hoses

Installation Notes and Tips

Verify the hose position, end diameters, and centerline length against the original part before installation. Inspect the mating necks, clamps, and nearby cooling-system components for wear or corrosion, and replace any damaged sealing surfaces before refilling the system. After installation, refill and bleed the cooling system according to the vehicle service procedure.

Quality Assurance

Gates manufactures this molded coolant hose to OEM-quality specifications for the listed applications. Part number 23522 is built as a direct-fit replacement for the confirmed lower hose positions on the supported Toyota Corolla, Toyota Matrix, and Pontiac Vibe models.
