Do I need to drain and flush the cooling system before installing this radiator?

Yes. Drain the old coolant completely, flush the system with distilled water if debris is present, then refill with fresh coolant. This prevents contaminants from clogging the new core.

Will the factory hose connections fit without modification?

These connect at the original hose ports—no adapters or custom fittings needed. Confirm hose condition before installation; replace any cracked or brittle hose while you're in there.

What's your return window if the radiator doesn't work out?

Contact ModSupply customer service directly with your order number for return eligibility and shipping instructions. Don't install if you're unsure about fitment.
