Coolant Header Tank - Expansion Tank for BMW F82 M4 — Overview

This is a replacement coolant header tank for the F82 M4, matching the factory-style expansion tank setup used on the S55 cooling system. If your original tank is starting to yellow, crack at the seams, or seep around the fittings, this is the part you replace before it turns into a bigger cooling issue. On these cars, brittle plastic in the cooling system is not something I like to ignore.

I’d pick this over trying to reuse an old tank anytime you’re already in there for cooling system service, especially on higher-mile F8x cars. It makes the most sense as a stock-style replacement if you want proper fitment and don’t need an aluminum race-focused setup. Just double-check the part numbers against your car, since BMW cooling components can vary by model year and production split.
