Hi,

I have installed Radium coolant tank.

1. Any idea why I see "air" in the middle of the side tube vs. air at the top only? Like, it should show the level of coolant.
- I looked inside, the coolant level is in the middle of tank. I should add a bit of coolant. Per Radium, the side tube should show 60% liquid and 40% air.
- Maybe during the drive the liquid moves and gets into top side of the tube from inside?

2. I also see small sign of leak. It might be from the cap not sealed properly? Or maybe top part that is designed to release any excess liquid.

Appreciate your thoughts before I reach out to Radium support.

No clue about the tube but there are different rating caps for the pressure. My Mishimoto tank came with a 3.2 bar cap.. I would suggest getting a different aftermarket cap.
