The BMW expansion tank or coolant reservoir houses the liquid coolant that stabilizes your engine’s temperature. These plastic tanks convey antifreeze through coolant hoses to the radiator and onto your BMW’s water pump. Due to their material, excessive winters or hot summers will inevitably deteriorate the expansion tank’s housing. It is highly recommended to replace your coolant reservoir prior to this happening. Since you’re already tinkering with the coolant system starting point, it’s best to work your way backwards and locate and diagnose each hose, thermostat, or water pump later in the system. offers free shipping on all our customer “in-haus” kits, we’re ready to ship your BMW expansion tank parts right now.
