Rein Automotive Expansion Tank/Coolant Reservoir | 17137787039
Make Sure It Fits
- 17137787039 is an expansion tank for BMW developed by Rein Automotive.
- The expansion tank on your BMW does exactly what it's name suggests. It holds coolant allowing the expansion of coolant capacity as the engine gets warmer and refills the cooling system.
- Additionally, it is the point at which your cooling system is refilled as servicing the cooling system.
- Being made of plastic and the high internal pressure it experiences, over time it can crack or lose its ability to seal at its cap or at the coolant hose and leak.
- This Rein Automotive expansion tank is manufactured to the exact specifications designated by BMW and is an affordable replacement for your BMW E46, E83, and E53.
WARNING: This product can expose you to chemicals, which are known to the State of California to cause cancer and birth defects or other reproductive harm. For more information go to www.P65Warnings.ca.gov.
