Frequently Asked Questions
Will this tank bolt up to my existing coolant hoses without modification?
Yes. This is designed as a direct bolt-in replacement using factory mounting points and hose connections. No adapters or modifications required.
Do I need to drain the entire cooling system to swap this in?
Partial drain is the smart move—you'll lose some coolant when you disconnect the old tank, but you won't need to flush the whole system. Refill to the proper level once the new tank is seated.
What about the cap and overflow line—do those come with this tank?
Tank assembly only. Verify your existing cap and overflow tube are in good shape before installation; if they're brittle or leaking, replace them while you're in there.
