Coolant Reservoir for 2015-2023 Ford Mustang EcoBoost/V6/V8 Coolant Overflow Tank SPELAB Over the course of time, the Coolant Reservoir Tank can emerge as a prominent eyesore within the engine bay of your 2015-2023 Ford Mustang EcoBoost/V6/V8. The original plastic reservoir tends to become fragile and hazy, increasing the risk of leaks and hindering visibility of the coolant level. The SPELAB Coolant Reservoir, constructed from 6061 aircraft-grade aluminum, ensures maximum strength through TIG welding and pressure testing. Unlike factory tanks that consist of two sealed plastic pieces, our fabrication method eliminates stress, cracking, and leaks. Additionally, aluminum dissipates heat, improving system performance and longevity. SPELAB’s Coolant Reservoir maintains compatibility with the factory cap (upgraded options available) and includes a sight glass for easy level checks. It's a direct, easy-to-install replacement for your stock reservoir, requiring only basic tools and less than 30 minutes. Manufactured at SPELAB's facility for stringent quality control, every step, from cutting to welding, ensures years of trouble-free performance.
