Do I need to drain the existing coolant before swapping this in?

Yes. Your system holds coolant that needs to come out before you disconnect the old radiator. Have a drain pan ready and dispose of used coolant properly.

Will my hoses reattach without modification?

Factory hose connections are preserved on this radiator, so your existing upper and lower hoses will bolt straight on. No custom fitting needed.

What's the return process if this doesn't fit my setup?

Contact ModSupply customer service with your vehicle details and what you've discovered during test-fit. They'll walk you through the next step based on your situation.
