Will this bolt straight in, or do I need adapters?

This mounts at factory rocker points — no adapters or modification needed. Drain your coolant, unbolt the old unit, bolt this one in, and refill. Your existing hoses and brackets work as-is.

Do I need to flush the system before installing?

Yes. Run a coolant flush to clear the block and lines of any sediment or old fluid before you install this radiator. Fresh coolant protects your new core and improves heat transfer.

What if it doesn't cool properly after install?

Check coolant level first — most cooling issues post-install are air pockets. Burp the system by running the engine with the cap off until coolant stabilizes. If temps stay high, verify your thermostat and water pump are functioning.
