Ok, my question might be ultra dumb... but here it goes. I read the howto on painting the white water bottle. It says to store the coolant fluid that was inside and replace the fluid when done... Well, when I took off the coolant bottle, I got some fluid on the engine and dumped the rest in a bucket. I wasn't sure if I was actually supposed to put that fluid back in when I was finished, so I threw it away. Well, anyways I painted the water bottle which came out really good. I now need to refill the coolant bottle with new coolant. What coolant should I use now that I threw away what was inside before...
