The engine bay of the 2021+ Ford Bronco is a masterpiece of technological advancement with either the 2.3L or 2.7L EcoBoost engine under the hood. All clad in black, the one eyesore is the factory plastic coolant expansion tank. Plastic coolant expansion tanks are both unpleasant to look at, but more importantly, prone to fatigue and failure over time due to continuous heat cycles of hot and cold. We took it upon ourselves to solve both problems and came up with the Mishimoto Aluminum Coolant Expansion Tank. Add some style and function under the hood with one of two available finishes, polished or micro-wrinkle black. Constructed from TIG welded aluminum, this tank is tough, and will withstand all the rough roads you and your Bronco take on. You'll never have to worry about it cracking or failing like plastic, because nobody wants to end their trip in a cloud of steam. The built-in sight glass allows you to easily check your coolant levels, and the internal baffling and submerged pickup tubes ensure that coolant is kept level and you never draw air into your system, to ensure optimal performance at all times. Since we designed this tank as a direct fit replacement, installation is simple and should take less than an hour. As with all of our parts, this tank is backed by our signature Mishimoto Lifetime Warranty.
