MITZONE Expansion Tank - Coolant Reservoir for BMW E60 — Overview
This is a replacement coolant expansion tank for E60 5 Series cars. It handles the usual job - giving the cooling system room for expansion and keeping the level sensor area where it should be. On these cars, cracked plastic tanks and seepage around the seams are common once the original cooling parts get some age on them. If your E60 is losing coolant with no obvious hose failure, the tank is one of the first places I check.
I’d pick this when you need a straightforward stock-style replacement and you’re not trying to overthink a basic cooling repair. It makes sense if your original tank is brittle, stained, or throwing low coolant warnings from an actual leak. While you’re in there, inspect the cap, upper hose connection, and nearby radiator plastics too, because E60 cooling systems usually fail in clusters rather than one part at a time.
