This is a genuine HONDA O-ring, part number 19222PH7003, specifically engineered for your vehicle's water pump. Its primary function is to create a watertight seal between the water pump and the engine block, preventing coolant leaks. A compromised seal can lead to coolant loss, overheating, and potential engine damage. Using a genuine HONDA part ensures proper fitment and material quality, designed to withstand the high temperatures and pressures within the cooling system. This O-ring is a critical component for maintaining the efficiency and longevity of your engine's cooling system. Regular inspection and replacement of the water pump O-ring, especially during water pump service, is recommended to prevent unexpected failures and costly repairs.
