Product Details

This Four Seasons Water Inlet line component is engineered as an engine coolant inlet for direct-fit service on Nissan cooling systems.

Common Repair Uses

• Replacing a leaking or corroded coolant inlet housing
• Restoring proper coolant flow at the engine inlet connection
• Addressing sealing problems at the thermostat housing area when the thermostat is serviced separately
• Repairing damaged bolt-hole mounting surfaces
• Correcting fitment issues caused by worn original aluminum components

Installation Notes

Verify the inlet diameter, bolt-hole spacing, and mounting flange dimensions before installation. Because the gasket or seal is not included, reuse should not be assumed; inspect the sealing surface carefully and install the correct seal for the vehicle application. Confirm the thermostat arrangement on the vehicle, since this unit is supplied without a thermostat.

Quality Assurance

Four Seasons 85351 is listed as meeting or exceeding OEM requirements for the specified applications. Confirm vehicle fitment against the model year and cooling system configuration before ordering.
