Frequently Asked Questions
Will this radiator work if I've upgraded to a turbo setup?
This is an OEM-spec unit designed for stock cooling load. If you've significantly increased boost or engine output, verify your cooling demand against this radiator's capacity before installation. Stock builds are fine.
Do I need to drain the entire cooling system to install this?
Yes. You'll need to drain coolant before removal and refill after. Refer to your service manual for drain points, capacity, and coolant type. No special tools required beyond basic hand tools and a drain pan.
What's the return window if the radiator leaks or fails after installation?
Contact ModSupply directly with photos and installation details. Genuine defects are handled on a case-by-case basis—don't assume a standard return window. Reach out right away if there's an issue.
