Default changing antifreeze on 2003 Honda Accord

Hi, i wanted to change the antifreeze on my 2003 Honda Accord 4D 4 cylinder. Is it a simple drain and fill? i know to to empty the reservoir tank and the radiator. those are easy but i read that i also need to empty the engine block which i dont know how to do. and also does my car have an engine block that needs to be drained? i wanted to know how hard it is and where its located. and is there any other hoses i need to drain or anything else i might need to do like a flush. thank you in advance.

Shop manual does not specify draining the block, only the radiator.

There is a cut-out opening in the underbody cover underneath the radiator. Reach through to turn the drain plug and allow coolant to drain into a catch pan. Crack the radiator cap to enable venting.

Remove/clean the reservoir and refill radiaotor and reservoir w/ fresh mixed antifreeze coolant.

Start engine w/ radiator cap loosely and warm engine (fans come on). Turn off engine, check coolant level, top up, and tighten radiator cap.

good luck
See you down the ROW
