Detailed Product Description

The Four Seasons 86348 engine coolant water inlet is manufactured from thermoplastic, providing resistance to heat and corrosion commonly encountered in engine cooling systems. Its 1.48-inch inlet diameter allows for optimal coolant flow, while the included gasket or seal ensures a tight, leak-free connection.

  • Addressing overheating issues caused by faulty coolant flow
  • Upgrading worn or corroded engine coolant components

Installation Notes and Tips

Ensure the engine is cool before beginning installation to avoid injury. Remove the old water inlet carefully, inspecting the mounting surface for debris or damage. Use the included gasket or seal to prevent leaks and tighten mounting bolts to manufacturer torque specifications. Since this part does not include a thermostat, verify the thermostat housing and thermostat are in good condition or replace separately if necessary.
