Subject: Re: Antifreeze 50% water question?

Yes, every brand of antifreeze I've ever seen needs to be diluted. If you're in a really cold climate, you might go to 60% antifreeze, but no more than that. Pure glycol actually freezes at a fairly high temp, like 15 degrees F or so. Don't ever let anyone tell you to run straight water. Doing so not only increases the possibility of both freezing and boiling, but also leaves the water pump unlubricated, and offers no corrosion protection. I would look elsewhere for the cause of your car running hot. Engine thermostat is one possibility. Or, driving conditions - if you're always in stop-and-go traffic, the temp will run a bit higher. Might be as simple as a miscalibrated temperature gauge.
