Features, Description, Q&A, Specs & Installation
Precise Radiator Seal. The Lower Radiator Hose O-Ring is designed to seal the radiator outlet connection on select GM trucks, preventing coolant leaks and ensuring efficient engine cooling. This replacement part allows for a straightforward fix of failed O-rings without the need to replace the entire hose assembly, saving time and expense. It is ideal for restoring the factory-updated radiator hose's sealing performance.
_x000D__x000D_Construction and Appearance. This O-ring is made from FKM, a durable fluorocarbon elastomer known for high resistance to heat and automotive fluids. It features a round cross-section with a smooth finish and is sized precisely with an inside diameter of 1.975 inches, outside diameter of 2.395 inches, and thickness of 0.21 inches, all packaged securely in a box to maintain part integrity.
_x000D__x000D_Installation. Installation is straightforward and requires no drilling or modifications. The O-ring simply replaces the worn or damaged seal on the updated lower radiator hose for a secure fit and reliable sealing performance.
_x000D__x000D_Warranty. The product is backed by a commitment to quality and supported by automotive experts to ensure satisfaction.
_x000D__x000D_Application. Designed specifically to fit the 2007 to 2014 6.6L Duramax Sierra 3500 HD models, this O-ring only fits the updated OEM radiator hose and will not suit the original factory-installed hoses from this timeframe.
