Detailed Description

Four Seasons 85146 is a replacement engine coolant water inlet built for cooling system service on 1993-1997 Geo Prizm, 1994-1997 Toyota Celica, and 1993-1997 Toyota Corolla applications. This Four Seasons Water Inlet part number 85146 is made from aluminum and follows OE-style dimensions for the inlet diameter, mounting height, and bolt spacing. It is supplied without a thermostat and without a gasket or seal, so it is intended for repairs where the inlet housing is being replaced as part of the cooling system service.

The Four Seasons Water Inlet product line focuses on engine coolant components that match factory-style fitment and function. For buyers searching for a Toyota Corolla water inlet, Toyota Celica coolant inlet, or Geo Prizm engine coolant water inlet, 85146 provides a direct replacement option for the listed vehicles.

This part cross-references Motorad CH6047 for the same application.

What It Helps Fix

• Coolant leaks at the inlet housing
• Cracked or corroded original aluminum housing
• Improper sealing at the coolant inlet connection
• Cooling system service when the thermostat housing is being reused separately
• Fitment issues caused by worn mounting surfaces on older Toyota and Geo engines

Installation Notes and Tips

• Verify the inlet diameter and bolt spacing against the removed part before installation.
• Because the gasket or seal is not included, source the correct sealing component separately.
• Inspect the mating surface for corrosion, pitting, or old seal material before assembly.
• Confirm thermostat requirements for the vehicle, since this inlet is supplied without a thermostat.
• Use the vehicle-specific service procedure for coolant refill and air bleeding after installation.

Quality Assurance

Four Seasons 85146 is listed as meeting or exceeding OEM requirements and is built as an OE-style replacement for the specified Toyota Corolla, Toyota Celica, and Geo Prizm applications.
