Bulletproof your 1986-1993 Mustang's cooling system with this direct-replacement stainless steel overflow tank from ACP. The factory plastic tank cracks, stains, and degrades over time, leaving the cooling system without the reservoir it needs to manage thermal expansion. This kit gives you a clean, durable solution that fits the original mounting location and works exactly as the system expects.
Functional overflow and recovery in one unit. The tank holds coolant during thermal expansion and allows the cooling system to draw that coolant back in once pressure drops and vacuum forms. Without a functioning overflow tank, coolant purges to the ground instead of returning to the radiator, leading to gradual coolant loss and potential overheating.
Polished stainless steel construction. Unlike the original plastic unit, the stainless steel body resists cracking, warping, and heat discoloration. The polished finish holds up under the hood without pitting or corroding, making it equally suited for a daily driver or a show-quality restoration.
Direct replacement fit. Sized at 14 ounces to match the OEM specification for the 1986-1993 Mustang, this tank replaces a damaged or missing unit and restores the cooling system to proper working order without modification.
