It wasn't that bad of a car. Exactly the same thing as the Alero, just a different body skin. Mine had the 3100 though. The same Haynes manual that I used for the Malibu I can use on my Alero. Point being, I never mix coolant, regardless of what the bottle says.

In many cases. I have no sludge built up in the ecotec, but I do believe that it is a contributing factor to all of those 3.4's with gaskets that went bad prematurely.

well dex cool can leave some sludge but it is nothing that will ruin your car. get a anitfreeze tester from wal mart or somewhere cheep when you put antifreeze in it hold it up to the light and you can see exactly what is floating around in there. as for your problem you need to do a pressure check of your cooling system. probably the simplest way is to go to a shop and watch them as they pressure test your system, and start from there. start by picking one general problem and focus there.

I bet one of the cooling fans took a dump or wasn't hooked back up in the repair, the Heater is just dispersing whats not being taken care of by the fans. Turn on the A/C max cold and BOTH fans should be running. Any time the temp needle is above half, one fan should be running.
