Stop coolant seepage at the lower radiator connection with the Gates Heater Hose Connector CO34942 — one of Gates' heater hose fittings built to route engine coolant reliably. Cataloged as an Engine Coolant Water Outlet and serving the radiator (lower) position, it drops in as a direct-fit replacement for the 2009-2018 Toyota Corolla, 2017-2018 Toyota Corolla iM, and 2009-2013 Toyota Matrix — see the Buyer's Guide tab for engine-level fitment. Gates designed these coolant outlets to fit and perform like the original for long service life, addressing the design, manufacturing and material shortcomings found in many aftermarket coolant connectors.

Features:

  • Improved seal design: helps deliver leak-free performance at the coolant connection.
  • Advanced weld process: consistent, durable construction.
  • Top-quality materials: help prevent warping and resist corrosion.

This Gates hose connector — also known as an hvac heater hose connector — carries engine coolant through the connection point, so a cracked, warped, or leaking original can drip coolant, cause seepage, or lead to a low-coolant condition. If the failed connector is the cause, this replaces it.
