7.3L. Heater Pipe to Engine. 14.70 x 2.62mm. 5.0L, 2018-20. 6.8L. With high output. 5.2L without supercharger.

Engine Coolant Pipe O-Ring – Ford (AC3Z-8527-A) is a Genuine OEM sealing component manufactured by Ford, engineered to provide a precise, leak-free seal within the engine’s cooling system on compatible Ford vehicles. This O-ring is a critical element that helps maintain proper coolant circulation, prevent fluid loss, and protect the engine from overheating — all essential for dependable performance and long-term durability.

Manufactured from high-grade, heat- and coolant-resistant elastomeric material, this OEM O-ring is designed to withstand continuous exposure to elevated temperatures, pressure changes, and the corrosive effects of long-term contact with antifreeze/coolant. Ford’s exact factory specifications ensure that this seal maintains flexibility, compression set resistance, and dimensional accuracy over time. Compared to many aftermarket alternatives, this genuine O-ring offers superior longevity and a reliable seal that minimizes the risk of coolant leaks.

Compatibility is specific to select Ford models and engine configurations, where the Engine Coolant Pipe O-Ring – Ford (AC3Z-8527-A) serves as a direct replacement for the original factory-installed seal. Its precise inner diameter, cross-sectional profile, and material durometer are engineered to match the mating surfaces of the coolant pipe and related components. This exact fit ensures optimal compression and sealing integrity when installed correctly, helping maintain stable engine operating temperature and preventing air intrusion into the cooling system.

For professional technicians, this OEM O-ring supports efficient cooling system service with predictable results, reducing the likelihood of repeat leaks and unnecessary diagnostic time. DIY mechanics benefit from a part that installs cleanly and restores proper cooling system sealing without modification — allowing you to complete quality maintenance with confidence.
