Do I need to drain the cooling system before installation?

Yes. Drain the coolant from the old tank before removal. Once installed, refill with the coolant type specified in your service manual — do not mix types.

Will this tank connect to the radiator hose without adapters?

It uses factory connection points and hose diameters. Verify the condition of existing hoses during install; replace any that show cracks or brittleness.

What tools do I need to remove the old tank and install this one?

Basic hand tools — a socket set and screwdrivers. Drain pan recommended. Refer to your vehicle's service manual for bolt torque specs and exact removal sequence.
