Radiator, BMW - G01 X3 30i, G02 X4 30i

The Genuine BMW radiator for your 2019+ G01 X3 30i and G02 X4 30i is an ideal replacement, whether for a failed or failing radiator, or simply as a preventative cooling system overhaul. This is the main cooling system radiator which sits behind the heat exchanger (also called a radiator).

If your radiator hasn't been replaced in the last 5 years or 60k miles, we recommend inspecting it or replacing it as a preventative measure. Be particularly sure to inspect the plastic inlet / outlet hose connections. The plastic gets brittle and fragile over the years as it sees cold and hot temps and the plastic breaks down. This can lead to a sudden crack and loss of coolant. Avoiding a blown radiator and overheating is one of the best ways to ensure long life for X3 and X4 engines.

This is a Genuine BMW X3/X4 B46 radiator with a two year warranty. Buying a Genuine part will usually be more expensive than an OEM or aftermarket brand but you are assured that it meets BMW's designs for fitment, performance, and longevity. It will also be the very latest design, incorporating any updates or revisions that an aftermarket brand typically will ignore.
