Parts for your 2016 Bmw X3-Head gasket

2016 BMW X3 head gasket — what it does and when to sort it

Yes, the 2016 BMW X3 (F25 LCI) absolutely uses a head gasket. BMW’s ISTA/TIS workshop procedures and the BMW parts catalogue (ETK/RealOEM diagrams) list a cylinder head gasket for the petrol N20 and N55 engines, as well as the diesel B47/N47 and N57 engines fitted to the X3 in 2016. It’s a multi‑layer steel (MLS) gasket designed specifically to cope with turbocharged cylinder pressures and modern cooling passages.

On this X3, the head gasket seals three critical interfaces at once: combustion chambers, coolant galleries and oil galleries. It keeps compression where it belongs, keeps coolant out of the oil, and stops oil sneaking into the cooling system. When it’s happy, the engine runs smooth, efficient and cool. When it’s not, you can see overheating, misfires, white exhaust steam, unexplained coolant loss, milky oil, or pressure building quickly in the expansion tank.

There’s no set service interval to replace a head gasket, but smart servicing protects it. For a 2016 X3, that means:

• Keeping the cooling system spot on — correct BMW‑approved coolant mix, fresh coolant at the intervals in the service book, and a healthy water pump, radiator and thermostat.
• Avoiding overheating — pull up if temps spike
