Yes - the low coolant sensor on this setup is VERY twitchy.
I use Fleet Charge, FWIW. I briefly flushed/filled with Final Charge but some people have had experiences with it ruining the low coolant sensor - even the revised one Freightliner came up with. So I did another flush/fill with Fleet Charge. So far, so issues.
Except.
I replaced the fill cap with a new non-OEM cap I got off eBay. Every morning after a long day's drive, the LOW COOLANT light would come on when I keyed the engine. So, I'd go open the cap and re-close it - the light would go out. Weird.
I ended up jut putting the old cap back on. No more issues.
Like I said: twitchy.
