Hey everyone. I recently noticed on my wifes chevy cruze that it was a little low on coolant. Being the super genius that I am, (sarcasm), I added regular antifreeze to it. That was a couple days ago. I noticed today that the windows were fogging up more than usual. We had hot food in the car so it may have been due to that. But it reminded me of when my friends car had a leaking heater core and it made the windows fog up like crazy. I looked online and found that you are not supposed to mix the orange and green antifreeze. Im sure most people already know this but this is the newest car ive ever messed with.

SO... what kind of damage did I cause? Its probably been drove about 100-125 miles since i added it. I am planning on taking it to the shop tomorrow for a coolant flush.

Any help would be appreciated!

The gelling thing is a rumor that started years ago. It came as a result of owners finding gelled coolant and blaming a intermix when, in fact, the gelling was caused by operating with low coolant. When air is present in a system using dex-cool, the coolant breaks down and a thick jello like substance results.....difficult to flush, it does eventually break down with flushing chemicals.

OP.......when you intermix dex-cool with a standard (green/blue ethylene glycol) based product it takes the 5 year suggested change interval to a 2 year suggested change interval of conventional coolant. This because conventional coolant becomes acid more readily in the presence of mixed metals.....in this case a combination of steel, aluminum, and cast iron parts used to construct the engine and cooling system.
These 'multi-metal' designs are what created the need for more stabilized coolants.....they prevent internal corrosion.

The odds are the minimal amount of coolant added won't have any real negative effect on anything but a coolant change would be good maintenance anyways if the car is over four years old.
