Detailed Product Description

Gates 23528 is a molded radiator coolant hose engineered to match the original hose path in the cooling system. The EPDM material is commonly used in coolant applications because it handles heat and coolant exposure in under-hood environments. With equal 1.29-inch end diameters and an 18.9-inch centerline length, this hose is shaped for the specified upper radiator-to-tee routing rather than a universal straight replacement.

This part cross-references Continental 66199 for the same application. It is a practical replacement choice when servicing a Toyota Corolla upper radiator hose, Toyota Matrix coolant hose, or Pontiac Vibe radiator hose in the listed model years. Gates 23528 is intended for vehicles that require the molded upper hose configuration shown in the fitment data.

Installation Notes and Tips

Confirm the hose route, end diameters, and molded shape against the removed part before installation. Inspect the mating necks, clamps, and nearby cooling 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 and check for leaks at operating temperature.
