Mercedes-Benz CLS63 AMG Sedan 219.377 6.3L V8 Expansion Tank Cap (Screw-On Type)

I needed a new expansion tank cap on my Mercedes CLA as the old cap after six years the seal had flattened and was allowing coolant to leak out of the cap and was leaving white chalky dried coolant on the top of the bottle, this cap is working perfect with no issues and best of all no more leaks!
