Genuine BMW OEM Oil Cooler O-Ring 17227613656

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 Does

The 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 integrity

• Prevent external oil leaks

• Protect surrounding components from oil contamination

• Ensure consistent oil cooling performance

Replacing O-rings whenever oil cooler lines or housings are disturbed is strongly recommended to avoid leaks after reassembly.

Common Oil Cooler O-Ring Failure Symptoms

A worn or failed oil cooler O-ring may cause:

• Visible oil leaks around the oil cooler or line connections

• Oil residue on undertrays or engine components

• Gradual oil level loss without obvious external damage

• Leaks appearing shortly after oil cooler or line replacement

Replacing the O-ring during service helps prevent repeat labour and potential engine oil loss.

Why Choose Genuine BMW OEM Seals?

Genuine BMW OEM seals are engineered specifically for BMW oil pressures, temperatures, and chemical exposure. Unlike generic O-rings, OEM parts ensure the correct material compound and dimensional accuracy, reducing the risk of leaks, premature failure, or repeat repairs. For critical engine sealing points, OEM replacement is the safest and most reliable option.
