"Check Coolant Level" in DIC...
Had a DIC message of "check coolant level" after start up after sitting for about a week. Checked level in res. and seems to be fine. Isn't getting hot or anything. Could be a fluke ? Suggestions?

I just went through this, and replaced the thermostat... no messages since.

The C6 doesn't have a coolant level sensor. The "Check Coolant Level" message is triggered by an algorithm that compares the rise in coolant temperature over a given period of time.

You can actually run the surge tank dry and not get a low warning. You can also get a coolant temp sensor misread to the PCM and trigger a warning.

Not trying to start a battle, but, I didn't say "coolant level sensor" I said "sensor"... If the temps are fine and the level is fine, I will still go with a sensor issue...

You're right about it could be a sensor issue -- I was just thinking that if he was getting 'normal' coolant temps on the instr cluster, that could rule out a faulty coolant temp sensor diagnosis.

No offense meant nor taken. Nothing wrong with a couple of CF'ers doing a little DDx, right?

Vig 3200 stall...mild I know, but I think it'll give me what I'm looking for, beside, they have a free "re-stall" program if I wanna bump it up to say, 3600-3800 sometime later.
As for the "check coolant level" dic message. I took the vette out today, no message in over 30 miles of city/hwy driving . Kept the coolant temp in the dic to monitor temp, never got above 187 degrees, stayed mostly in the 181-183 range. I'll continue to keep an eye on it and have the shop do a look-see for me as well.
FWIW, the overflow tank is at same level as it's been for months.

I have read page 6-654 in the service manual.
My 'sensor' would be the temp sensor - since it has to provide multiple readings to get a rate over time. Too many glitches in any computer system. I think the key is if the message is persistant it is prolly some failure or pending failure but if it goes away and doesn't return it is a glitch...

You can also get the "check coolant level" warning by starting a cold engine and driving off immediately instead of waiting a few seconds. That confuses the algorithm that calculates coolant level by flow and temperature.
