ICE engine coolant replacement DIY

This past weekend i did a couple service items on my 2006 Prius including ICE coolant, Inverter coolant, and tansaxel fluid change. I spent a good hour and a half filling the ICE coolant, running the hot coolant storage tank motor and all other recommendations i've read here and in youtube videos. I've put back in at least as much coolant as i originally took out. Yesterday after a quick trip out i decided to check the levels again and noticed that under the radiator cap was not at the same level it was when i last left it so i topped it off again. I did have to put in much as i could still see the fluid in the line just above the 90 elbow. Wanting to make sure it was right today after another quick trip i checked it again, and once again it was just above the 90 elbow but not right to the top, i topped it off again.

My question is, is the proper level just above that elbow or should it be right to the top and the system is still working minor air bubbles out? I dont hear any bubbling and the pump sounds proper.

I ask because when i checked it before i drained it it was right to the cap but not sure if that was a fluke. Also note the reservoir has maintained its level at the full line. Any thoughts?

Thanks in advance.

 

Thanks, thats what i was planning on doing just wanted to make sure i wasnt going crazy.

 

It's definitely under the rad cap that I'm looking at. The line has a 90 degree bend about 2 inches down that heads towards the front of the car. " coolant should be right to the top" is what I wanted to double check so thanks for clarifying. I've left the plastic cover off entirely ATM sitting on my work bench (who designs a covercover you can easily check the fluid levels). Hopefully it's full ( or close to) as I had put back in the same amount of fluid as I took out it just seemed weird the rad line was always a inch below the top after a quick drive.

Thanks again for the help

 

I think my phone auto corrected that this morning. Should have said rad level (as in the fluid level), was always a inch below the top after a quick drive. Even today a couple quick drives and its still taking ever so slightly more fluid. Time will tell how long it will keep taking fluid.

 

Thanks! Yea it was likely trapped air in the CHRS.

I *think* its good now after another trip the fluid is still right up to the top. Going to give it a couple more days of checks but hopefully it holds.
