2014-2017 Infiniti Q50 OEM Radiator - Fits 3.5L & 3.7L Engines

Do I need to drain the entire cooling system before swapping in the new radiator?

Yes. You'll want to drain coolant before disconnecting hoses and mounting bolts. Capture the fluid in a drain pan and dispose of it properly — don't reuse old coolant from a failed radiator.

Will this radiator work if I've upgraded to a different coolant type?

As long as you're running an approved coolant for your year Q50, this radiator handles it. Check your owner's manual for the correct type — mixing incompatible coolants can cause buildup. Flush the system before install if you're unsure what's in there.

Do hoses and clamps come with this, or do I need to source those separately?

Radiator assembly only — you'll need to reuse or replace hoses and clamps depending on their condition. Inspect them during installation; if they're brittle or leaking, replace them while you have the system open.
