Thanks Steverino I never looked at the tank all that closely, just going by what they told/sent me. I figured in either case that the switch bypass would fix the issue, whether there was something inside the tank telling the switch (incorrectly) that the level was low OR if it was a bad switch. Please correct me if I am wrong, but as long as the SHVCS warning isn't being displayed, I can just install the bypass and it shouldn't come back? Doug?? None of the fluid reservoir tanks in my 2011 Volt or my 2017 Bolt have a float that I have seen. For sure the battery coolant reservoirs do not.
