    Nice. Didn't even think they would do (not do) that.

    That's a double dose of humble with extra humble on the side, hold the pride. That's one of those things where it happens and you start sweating in your car. Just gets real hot all of a sudden. Good story.

    Car had been sent to d3 and had installed most every thing they sell for a Stsv. And it must have slowly leaked out. And the owner at the time never drive it hard.

So I gunned it and it went in to limp mode coasted to side of road car stalled out and would not stay running. I tought I killed it but it turns out the s/c had no coolant in it at all topped it off and went on my way after I reset it.

    i mixed a little royal purple purple ice try and keep it running a tad cooler with my dexcool when i upgraded to timmy c heat exchanger and had to put new coolant pump on for supercharger system, took a while to get all the air out, gm service information states to pull cover off top of charger and the cap off the resvoir and fill resvoir until you see it about to run out top of charger, even after doing that and manually cutting the pump on and off i still kept having ot add coolant to mine for a week or so to bleed all the air out.

    It doesn't leak. It evaporates I'm pretty sure. The charged air cooling system isn't a sealed/pressurized system that purges air like your regular cooling system (at about 15psi). It is somewhat sealed, but not to the extent of the regular cooling system.

    Your intercooler gets VERY hot. Especially for those of you in the southern climates. Pop your hood after driving it. Touch that big black thing on top of the engine with your hand. Chances are you'll burn it. That is where that coolant runs through (in 4 laminer cores).

    And can we quit calling it GM coolant. It's Dexcool and more than GM uses it. It was just a proprietary mix developed by GM and Havoline (or maybe Texaco), I forget. G-05 on the market also, is a modified version of Dexcool (for the simplest explanation here, I am not going to get into the exact chemical breakdown between the two), and that is what Chrysler and ford like to use. But the rest of the world uses a Dexcool or similar substitute. Many other brands make suitable Dexcool coolants. You don't need to go to the GM dealer and get specific "GM coolant".
