Tonight I got a "check coolant level" on my C6's DIC - the level is fine so I intend to take it to a local chevy dealer that sells corvettes - my question is does anyone know if there are great similarities between the C5 and C6 DIC and general engine systems? I wonder if a vette tech who is good with C5's would be worth their salt on a C6 especially since not many are floating around yet and probably fewer have had problems - any guesses or opinions? Has anyone else had a similar DIC message yet? Sure appreciate some help I am biting my nails with concern!

 

The Master GM Mechanic where I live has had to go to several C6 classes. However, today the mechanic does not learn everything. When a problem arrises he goes on line to GM and he is told what to do. If he is a good technitian, you will not have any problems. Much depends on the technitian.

 

when i had the window probem with my C-6 the dealer called the GM hot line and they told them what to do and it fixed the problem.

 

Where you going down a very steep hill? If so don't sweat it.

 

thanks - vette tech said it was a bubble in the container - they pressure tested it and ran it for codes without finding anything oh well - it was the 828th one made.

 

The tech not only goes on line to GM, but also has a direct telephone line for unique (aren't they all) problems.

 

Looks like GM is aware of this condition allready

05 Chevrolet Corvette Information on Low Coolant Message
.

The following diagnosis might be helpful if the vehicle exhibits the symptom described in the PI.

Condition/Concern:
2005 Chevrolet Corvette low coolant message.

Recommendation/Instructions:
The 2005 Chevrolet Corvette utilizes an algorithm-based low coolant level system which eliminates the need for the coolant level sensor previously positioned inside the surge tank. The algorithm (a mathematical calculation) measures a difference in temperature readings, based on engine coolant temperature and engine speed to determine if the cooling system has a low coolant condition. After vehicle start up, the ECM sends a GMLAN engine RPM and engine coolant message to the BCM. The BCM sends a Class 2 message to the HVAC control head. The HVAC control head uses engine coolant temperature and engine RPM to calculate the algorithm. This system is capable of losing 2 full liters of coolant before triggering the Low Coolant warning message. Because the surge tank holds approximately 0.8 liters when filled to the proper level, it's possible that a Low Coolant warning message is not triggered, even though the surge tank is completely dry.
