DESCRIPTION

This is the exact same expansion tank cap as originally fitted at the factory—ensuring perfect fitment, correct pressure regulation, and long-term reliability.

A faulty coolant cap can lead to poor system pressure, coolant leaks, or even overheating. If you’re replacing your expansion tank, dealing with cooling system issues, or simply performing preventative maintenance, this is the correct cap to use.

Suitable for a wide range of late-model BMWs, including E90, F10, F30, E70 X5, and many others, this OE cap is designed to maintain the specified pressure in your cooling system—just as BMW intended.

HELPFUL TIPS

The expansion tank cap also acts as a safety valve, designed to release pressure before your hoses, fittings, and radiator bursts.

Great quality OEM replacement at an affordable price. These do need to be changed periodically.

Ordered some service items ready for when next needed and it always amazes me how good the service is in getting the parts delivered. Ordered around lunchtime and delivered early the following day. Quality parts and cheaper than the dealer every time
