Will this bolt directly into my engine bay?

Yes. This mounts at factory points with no drilling, adapters, or modifications. Drop-in replacement.

Do I need to flush my cooling system before installation?

Flushing is strongly recommended when swapping a radiator—old coolant debris can damage the new core. Drain, flush the system thoroughly, then install this radiator with fresh coolant.

What about hose clamps and fittings—are those included?

The radiator assembly includes factory hose connections. Reuse your existing clamps and hoses if they're in good condition; replace them if they show wear or cracking.
