Do I need to drain my coolant before swapping this in?

Yes. Flush your system according to your owner's manual before installation. You'll need fresh coolant compatible with your Q50's specifications.

Will this fit without removing other components?

It bolts at factory mounting points, so you won't need custom brackets. However, hose disconnection and some underbody access work is standard for radiator replacement.

What if the radiator arrives damaged?

Document damage with photos and reach out to ModSupply customer service immediately. Radiators can't be installed if the core is compromised, so replacements are handled quickly.
