Will this mount directly to my engine bay without modification?

Yes. This unit mounts at factory points—no drilling, brackets, or adapters needed. Bolt it in place using existing hardware.

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

Yes. Run a full system flush before swapping in the new core. Debris or old coolant residue can clog passages and reduce cooling efficiency. Use distilled water and a commercial flush product, then refill with the correct coolant spec for your engine.

What's the return process if this doesn't fit or work as expected?

Contact ModSupply customer service with photos and your vehicle info. Most radiator returns are processed within 30 days of purchase if the unit is unused and original packaging is intact. Freight costs for oversized items may apply.
