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.
