Motorad Engine Coolant Filler Neck

The Motorad Engine Coolant Filler Neck (also called a coolant outlet, water neck, or coolant fill housing) is a replacement part for the engine cooling system. It gives coolant a sealed path to enter and leave the engine, and it is a common point for filling and bleeding the system.

Key Features:

• Designed as a direct replacement for the original coolant filler neck
• Helps keep the cooling system sealed so coolant does not leak
• Built to handle the heat cycling and pressure of engine cooling systems
• Made by Motorad, a supplier of thermostats, cooling system components, and related parts
• Helps prevent overheating and coolant loss caused by cracked, corroded, or leaking housings

Replacing a worn or damaged filler neck helps restore proper coolant flow and keeps the system holding pressure. When you replace it, it is good practice to also inspect the thermostat, gaskets or seals, and hoses.
