My orginial plans were to flush my cooling system today but my schedule became very tight so I had it done. My overflow bottle was still nasty from the Dexcool as they didn't bother to take it off. So i took it off after the flush and cleaned it myself. I got curious to what the coolant looked like that went into it so I used a large syringe with a tube to suck some out and see if it was clean and the right color, hoping there was no dex cool in it. Well it was clean and i just squirted the stuff back in while talking to my my 4 year old to come away from a big hole at my house. Could not have been more than a ounce or so. Well, heres the kicker. Its the same syrgine I used on my supercharger fluid back in Dec and there may have been some residue left in it. I didn't think about it until after I already squirted it back in.

Should I have any concern?
