Mustang Mishimoto Polished Aluminum Coolant Expansion Tank
Mishimoto has created a great looking and functional expansion tank to replace your factory 2015-2018 Mustang expansion tank. The tank is a direct replacement for the factory tank, but improves performance by adding key elements to the tank.
The expansion tank is internally baffled to prevent coolant from excessively moving during spirited driving. This will prevent air from entering the engine while accelerating, braking or cornering.
The aluminum tank has been designed to improve looks with its polished aluminum finish. It retains the factory cap, making this a truly bolt in installation. The tank is finished off with an easy to read sight tube, that will allow you to check your fluid level hot or cold without opening the tank.
Liked the look of this tank and the fact it had a fluid level tube on the side was what won me over other brands/versions. After a year the level tube on the side became brittle and began leaking substantially. LMR's service however was top notch on getting me a refund even after a year has gone by. I think if they removed the level tube all together or used higher quality materials this tank would be perfect. I ended up buying a new tank without the level tube on the side.
