Frequently Asked Questions
Will this tank work with my existing coolant hoses and cap?
Yes ā this is a direct bolt-in replacement that uses factory connection points and accepts the OEM cap. No hose modifications or adapters required.
Do I need to flush the cooling system before installation?
You should drain the old coolant before swapping tanks. Reuse the same coolant type or perform a full flush if you're switching brands or specs.
Will this tank hold more coolant than the factory plastic tank?
Tank capacity is not specified ā assume it matches OEM volume. If maximum capacity is critical to your build, test-fit and measure before final installation.
