Right now I am sitting at Karl Chevrolet in Ankeny and they are looking over my car. I brought it in because I had gotten a low coolant warning on my DIC, well I filled it back up to the full line and drove it for about 3k miles than I got the low coolant warning again. I have looked it over pretty good, no signs of any leaking or any other signs of problems like puddles white smoke in the exhaust etc..

Any idea where it could possibly be leaking?

 

mine does it occasionally when its cold

 

put coolant in mine every 30 k klms or so, no leak, pressure is good, no white smoke, no bad smell, i dont know. its a mistery!

 

same thing, have had mine for a little over a year and have had to top her off about 5-6 times...

 

same here. i wonder where it goes because the car run 110% so i'm 99% positive its not the head gasket, but there is no leaking anywhere. I even got a lemon law check from gm because they couldn't figure out the problem.

 

did they fill up the radiator coolant or did they fill up your intercooler coolant. cuz i've seen when your intercooler gets low that the light comes on

 

There's no low-level sensor for your I/C system, just the engine coolant.

 

I don't think the rad can leak because it's had for a rock or debris to get to it (it's behind the h/e) I'd say it's not leaking...if it is I'd say head gasket but let's not go there.

 

Well guys, they put the pressure tester on it for about 2 and a half hours and imagine that, no drop in pressure, no puddles.. not even a drip.

Looks like shes not leaking.

glad to know im not the only one with this little quirk

 

i get the low coolant message on my car to when I really get on it. No leaks or problems so im not worried.

 

Me too. I had the "Low Coolant" message come on while I was doing a pass down the 1/4 mile track. I was pretty much laughing when I saw it.

 

I think when the coolant moves around in the tank on a hard pull the car thinks the level is low. Never had it come on during normal driving, and my car stays at 178-181 degrees F.
