Will the hose connections fit my 240SX's existing coolant lines?

These are OEM factory connections, so they'll match the original hose routing and clamp points on your engine bay. Inspect your current hoses before installing — if they're cracked or brittle, replace them while you're in there.

Should I flush or pressure-test this radiator before putting it in?

Yes. Run a flush to clear any debris from sitting, and check for leaks under pressure before bolting it down. A used radiator can hold sediment from its previous life — cleaning it extends its lifespan.

What if I find internal corrosion or a slow leak after I receive it?

Inspect it immediately upon arrival. Document any damage with photos before installation. Contact us with details so we can discuss your options — condition issues should be flagged right away.
