This is our ZZPerformance upgraded aluminum coolant tank for the 98+ W-Body/3800 cars. This coolant tank features full aluminum construction with CNC brackets and cap provision, all powder coated wrinkle black. The tank uses a built in sight glass on the side to ensure proper coolant level. When you upgrade to our ZZP aluminum versions of each you can ensure your coolant system remains leak free all while looking great under the hood. This is a direct replacement coolant expansion tank for the 98+ W-Body chassis. Simply remove your stock hoses, unbolt your coolant tank from the front of the engine bay, and swap everything over. Designed and fabricated in house at ZZPerformance in Wyoming, MI.
