Dash? Hot? Normal?
Please clarify.
Are you meaning the DIC reading, which is very accurate.
OR, the temp gauge, which is 'close'.
My 'SISU' runs temps from 190-210 and sometimes 220 on hot AZ days.

 

Well, it's been hitting 214 and it's only in the 60s or low 70s.

 

Post #1 said 210. Now you say 214.
Either one is still within the acceptable range of what GM states as normal temp range for the SS.
You need to figure out where your lost coolant went and burp the system to clear any air.
If there is an air bubble, clearing it may drop the temps a few degrees.

 

Drive that thing.

 

You ever tried to drive in Los Angeles, the highest the DIC has ever shown for average speed is around 21MPH and we never reset anything so it over whatever the default is.

 

"and we never reset anything so it over whatever the default is."
I have no idea what you're trying to say here.

 

I also do not reset my average speed.
In AZ I average 24 MPH. as I do a lot of city driving.

 

No matter what, the t-stat does not cool. Getting hot is a function of radiator/fan/coolant flow. The fact that the temp is above 180F indicates the t-stat is working. If the t-stat was stuck closed the temp would rise much higher than 217.
Coolant does not just evaporate, it has to go somewhere, on the ground or out the tailpipe. Sometimes if there is a tiny hole somewhere coolant can escape as a vapor, you can smell that if not see it.

 

Or the oil can leave the cooling system, going into the engine oil. Coolant and transmission fluid can also mix, if the radiator is bad.

This is an SS, so coolant can also leave the system through the turbocharger, either into the engine oil, or into the exhaust. Or the oil cooler could be leaking, externally (onto the ground) or internally (into the engine oil).

 

I guess lazino isn’t going to follow up on their thread. I see they’ve been back on the site several times since their last odd post.
