Coolant Expansion Tank With Cap For BMW E53 X5 Land Rover Range Rover L322 4.4L 4.8L

This coolant expansion tank is a direct replacement for BMW E53 X5 and Land Rover Range Rover L322 models from 2003 to 2006 with V8 4.4L or 4.8L engines.

It comes with the cap, but note it does not have a sensor—so it's ideal if your original tank is cracked or leaking.

Made from black plastic, it meets OE specs and includes a 1-year warranty.

Part numbers include 17137501959 and 17117639022.

Brand new and ready to install.

If your coolant system needs some love, this is a good place to start.
