: S/C coolant level???

A couple of weeks ago it was pointed out to me that my s/c coolant level was low... I picked up a bottle of the GM coolant and topped it off. Since then, I've added about a quart of coolant to the system. Seems like half the time I check it, I have to add more. There are no signs of leaking anywhere. I have been checking it while warm, cold, running and off...
Could there be an air pocket that hasn't worked it's way out. Are there seals within the cooler that could have blown causing coolant to be injected into the s/c. This is a small reservoir so adding a little at a time would take a few times to fill the system but I'm a bit concerned with why it went low to begin with.

Update, just found on an xlr site the "proper" way to fill the s/c coolant. I am going to fill the coolant at the s/c by removing the cover plate. We'll see if this does the trick.

After the dealer flushed mine, I had to keep adding a little at a time for a while.

Either the fill cap or the top of the S/C. The fill cap is the easiest. It is located by the battery.

If its to low and you drive hard and get the iat2 temps to high the car will go in to limp mode to keep you from melting it down. Ask how I know lol.

Takes GM antifreeze/coolant, same as the radiator.
I finally popped the cap on the s/c and coolant is defiantly full. Everything has been good the last few times I checked so feeling much better now.

When you buy a car with only 7500 miles you just assume its all good. Wrong 20 miles in to the 180 mile ride back home with the car and a E550 mb with a dad and two teen boys in it come up along side me and start pointing at my car. 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.

Factory forget to fill it and previous owner never pushed the car.

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.

My car just went in to limp mode. How do I rest 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".

They sell Dex-Cool at every auto parts store.
