The factory coolant expansion tank on the 2015-2021 F-150 and 2017-2021 Raptor is a multi-piece plastic assembly that can degrade over time and lacks the durability demanded by hard-working or performance-oriented truck builds. Moroso's direct bolt-in replacement swaps that plastic unit for a fabricated aluminum tank that fits all F-150 trims, all three engine options, and the EcoBoost Raptor variant without any modification to the surrounding hardware.
Fabricated aluminum construction. The tank replaces the OEM plastic housing with an aluminum body that resists heat cycles, pressure fatigue, and the kind of underhood abuse that eventually cracks or warps the stock unit. It accepts polishing, chrome plating, paint, or powder coating, so it can be finished to match the rest of your engine bay build, or left in its natural aluminum state.
Internal baffle controls coolant movement. An internal baffle keeps coolant from sloshing during acceleration, braking, and cornering. Stable coolant movement helps the system maintain consistent pressure and prevents air pockets from forming in the loop, which matters most during hard driving or towing.
Billet aluminum radiator neck with factory cap compatibility. The radiator neck is machined from billet aluminum and sized to accept the factory pressure cap. Compatible caps include Ford 3M5H8100AD, Stant 10262, and NAPA 703-4112, so sourcing a replacement is straightforward at any parts counter.
