Will I need new hoses and clamps when I install this?

Depends on the condition of your current hoses. If they're cracked, split, or showing age, replace them now—it's cheap insurance. New clamps are always a good call, but the radiator itself reuses your existing connections.

How do I know if this radiator is clean inside before I bolt it on?

Flush it before install. Drain any remaining coolant, run distilled water through it, and inspect the tanks for sediment or corrosion. A clogged radiator defeats the purpose of swapping it out.

What if I find a crack or leak after I get it?

Test-fit it in the engine bay before final installation. Fill with coolant and run the engine at idle for a few minutes to spot leaks early. Returns are processed through modsupply.com's standard policy if damage is discovered on arrival.
