Specifications

Water Necks and Thermostat Housings, Allstar Performance Aluminum Water Necks, 45 degree, Swivel, Aluminum, O-ring, Each

Allstar Performance aluminum water necks are designed to rotate 360 degrees, allowing various radiator hose routing options for custom engine cooling applications. The water necks hold the thermostat in place so it can open and close to regulate coolant flow. The thermostat creates an opening in the water neck that allows coolant to flow from the radiator to the engine. Allstar Performance water necks are made from die-cast billet aluminum for strength and durability and are available in a range of styles and finishes to meet your needs. Order the model for your application.

Additional features and benefits:
• Allows for more flexibility in routing radiator hoses, which can improve engine cooling and make it easier to connect hoses to the engine
• A swivel water neck makes it easier to connect radiator hoses to the engine, especially when connecting left and right hoses
• Thick mounting flange prevents warping and provides a positive engine coolant seal
• Chrome-plated finish for lasting beauty, some swivel water necks are made with hard coat anodizing to improve wear and corrosion-resistance
• Stainless steel mounting hardware and an O-ring for sealing the base of the water neck to engine are included
