Product Details

Four Seasons 85417 is part of the Water Inlet product line and is engineered as an engine coolant component for vehicles that use a separate inlet housing without an integrated thermostat. The aluminum construction supports a precise fit at the cooling-system connection point, while the OE-matching design helps maintain proper coolant routing in the engine coolant system. This part cross-references Dorman - Conduct-Tite 85417 for the same application.

Common Problems This Part Can Address

• Cracked or corroded coolant inlet housing
• Coolant seepage at the inlet connection
• Improper sealing at the thermostat housing area when the inlet is serviced separately
• Fitment issues caused by a worn original water inlet
• Cooling-system service needs on a Toyota RAV4 or Scion tC

Installation Notes and Tips

Verify the inlet diameter, bolt-hole spacing, and mounting flange width against the original part before installation. Because the gasket or seal is not included, reuse is not recommended if the existing seal shows wear, flattening, or coolant staining. Confirm that your vehicle uses a water inlet without thermostat before ordering part number 85417.
