I've recently noticed that my coolant level is dropping and after periods of driving, the coolant boils out of and overflows the overflow container. Although the car doesn't over heat, if I run the AC the temp gauge runs high. We've been experiencing 100+ wheather here as well. Any ideas what this could be?

Make sure your coolant is properly mixed, if thers too weak the coolant will boil and not cool effectivly, if its too rich it wont cool efficently either.

Change and flush the coolant for now and have the radiator cap tested.
