Moroso Cooling System Expansion Tanks

4.71 out of 5 stars 104 Customer Reviews

These expansion tanks are perfect for cars with low-mount radiators to provide a convenient filling location and to bleed off unwanted air. Versions are now available with rugged 6061-T6 billet aluminum filler necks welded to the tank to withstand the continuous removal and installation of the cap. They're 100 percent pressure- tested to eliminate leaks, and they accept a standard-size radiator cap (not included).
