Naka bili ako ng second hand Honda idsi 2004 a 13yr old car w/ 81k kl. reading odometer

previous owner used water on its cooling system never mention if its distilled or tap water( ayaw na kasing mag reply inquiry ko. I do have plans of draining it or perform flashing(flashing solution) procedures, but I'm a bit worried about all the dirt residue will come out that will have a possibility to trap on its way out.

Please advice me what to do...
1. just drain the old cooling liquid then replaced w/ distilled water
2. perform flashing procedure (flashing solution) then replaced with distilled water + coolant solution 50/50.

please help me decide

I think best advise po no. 2 pero mas ok po kung pure coolant po ang gagamitin.
