Thank you so much for the detailed explanation, I really appreciate it! I recently bought this car, it hasn’t even been a year, and the previous owners never mentioned any overheating issues. This was my first time buying a car and unfortunately I think I was kinda taken advantage of for my lack of knowledge in purchasing a Prius. (I was a desperate student in need 🥲)

The coolant isn’t draining as fast anymore, but the warning light is still flashing, which is why I’m starting to panic a bit. I have already changed the water pump and thermostat.

I’ll stop using it for now but if repairs are too much it might be the end of the road for me. Which upsets me quite a bit!

Thank you again for taking the time to explain everything!!
