Genuine BMW OEM Oil Cooler O-Ring 17227613656

Description

The Genuine BMW OEM Oil Cooler O-Ring (17227613656) is a critical sealing component within BMW’s engine oil cooling system, designed to prevent oil leaks at the oil cooler line and housing connections. Manufactured to BMW’s exact factory specifications, this O-ring ensures a reliable, leak-free seal under high oil temperatures and repeated heat cycles.Oil cooler pipes and hoses are responsible for carrying hot engine oil away from the engine, allowing it to be cooled before returning to critical lubrication points. The integrity of the sealing O-rings is essential—any deterioration can lead to oil leaks, pressure loss, or contamination. Over time, exposure to heat, pressure, and ageing can cause O-rings to harden, flatten, or crack, making replacement essential during servicing or oil cooler repairs.As a Genuine BMW OEM part, this O-ring is the same component supplied through BMW dealerships and used by BMW service departments worldwide. BMW works with leading OEM manufacturers such as Hella, Behr, and Bosch to produce components to their precise standards, ensuring correct material composition, durability, and fitment.What This Part DoesThe oil cooler O-ring seals the interface between oil cooler lines and the oil cooler or engine housing. Its role is to:Maintain oil pressure integrityPrevent external oil leaksProtect surrounding components from oil contaminationEnsure consistent oil cooling performanceReplacing O-rings whenever oil cooler lines or housings are disturbed is strongly recommended to avoid leaks after reassembly.Common Oil Cooler O-Ring Failure SymptomsA worn or failed oil cooler O-ring may cause:Visible oil leaks around the oil cooler or line connectionsOil residue on undertrays or engine componentsGradual oil level loss without obvious external damageLeaks appearing shortly after oil cooler or line replacementReplacing the O-ring during service helps prevent repeat labour and potential engine oil loss.Key FeaturesGenuine BMW OEM sealing componentBMW part number 17227613656Designed for BMW oil cooler line and housing connectionsManufactured to BMW factory material and tolerance standardsResistant to heat, pressure, and oil exposureEssential replacement during oil cooler or line servicingCompatibility(Vehicles still in production are shown with a “+”)This oil cooler O-ring fits a wide range of BMW, MINI, and Rolls-Royce models equipped with compatible BMW oil cooling systems, including:BMW 1, 2, 3, 4, 5, 6, 7 & 8 Series (F-Series & G-Series)BMW M models including M2, M3, M4, M5, M8, X3M, X4M, X5M, X6MBMW X-Series: X1, X2, X3, X4, X5, X6, X7BMW Z4 (E89 & G29)MINI Countryman F60Rolls-Royce Ghost, Phantom & Cullinan (BMW-based platforms)BMW Motorsport applicationsFor full chassis and production year coverage, please refer to the detailed fitment list above or confirm via BMW part number matching.Why Choose Genuine BMW OEM Seals?Genuine BMW OEM seals are engineered specifically for BMW oil pressures, temperatures, and chemical exposure.
