Common Repair Uses

• Replacing a cracked or corroded coolant inlet housing
• Restoring proper coolant flow at the thermostat housing area
• Addressing coolant leaks at the inlet mounting surface
• Repairing damaged bolt-hole or flange sealing surfaces
• Servicing a Nissan Sentra, 200SX, or NX cooling system with the correct inlet configuration

Installation Notes and Tips

Verify the inlet diameter, bolt-hole spacing, and flange width against the removed part before installation. Because the gasket or seal is not included, transfer or replace the sealing component as required for the repair. Clean the mating surfaces thoroughly and inspect the thermostat housing area for corrosion or pitting before reassembly.

Quality Assurance
