Do I need to drain coolant before swapping this in?

Yes. Drain your system fully before disconnecting hoses and removing the old radiator. Refer to your service manual for coolant capacity and refill procedure — that's where you'll find the exact amount and bleeding sequence for your Cube.

Will this bolt straight to my engine bay?

It's designed for your model's factory mounting points, so the frame connection is direct. Hose routing and fitting orientation are OEM-spec — test-fit after installation to confirm all connections seat properly before running coolant through the system.

What if the radiator leaks after I install it?

Inspect all hose connections and clamps first — loose fittings are the most common leak source on fresh installs. If the core itself is compromised, contact ModSupply customer service with photos and a timeline of when the failure occurred.
