Do I need to drain the cooling system before pulling the old radiator?

Yes. The old coolant will spill when you disconnect hoses. Catch it in a pan if you plan to reuse it, or dispose of it properly at a local recycling center.

Are the radiator hoses and clamps included?

Radiator only. You'll use your existing hoses and clamps from the old unit, or grab new ones if yours are cracked or hardened.

Can I install this myself with basic hand tools?

Yes. You'll need wrenches to unbolt the mounting brackets and a screwdriver to loosen hose clamps. No special equipment required.
