Do I need new coolant hoses when I install this?

Inspect your existing hoses before installation. If clamps still grip tight and hose material shows no cracking or deterioration, reuse them. If hoses are brittle or leaking, replace before installation—old rubber can fail shortly after a new radiator goes in.

What coolant type should I fill this with?

Use the same coolant your vehicle originally came with—refer to your owner's manual for type and mix ratio. Do not mix coolant types. Flush the system completely before filling to avoid contamination from old fluid.

Can I test this radiator before final installation?

Yes. Once mounted, fill the system halfway, run the engine for 2–3 minutes at idle, and check for leaks at all connection points and the tank. If no leaks appear, drain and refill completely. This confirms the unit holds pressure before you button everything up.
