You can check for fluid at the bleed/fill port on the driver side front corner of the engine near the supercharger but that does require opening up the system.

if you remove the lower splash panel you can reach up on the d/s and feel the pump. if its vibrating its working. understand the oem pump only pushes 3 gpm its not much compared to other aftermarket pumps. I run a emp29 set at 2900 rpm pushing 10 gpm thru an12 hoses and a stage 2 interchiller

Also, many pumps will shut off if they don't detect the load from the coolant so you want to check the pump to see if it is on shortly after key on if you don't detect fluid movement in the lines.

The problem with checking the pump is that if you have air in the system and the pump isn't primed it can be running and no coolant is moving. So checking the pump is the first step but then you want to check the hoses or the bleed (or the reservoir if you have an external/aftermarket reservoir).

Stock 2016 Z06 system. The plastic tank has two small bubbles at the top of the tank, so unless there is air somewhere else, I believe I have a good bleed. Ambient temps are fairly high for a lot of the year here and I wanted to check the pump just to make sure all is well. The car doesn't seem to be running as hard as it has in the past and it's one thing to check. Currently 43k miles. I'll see if I can get to the pump for a listen.
