Bought my caddy a week ago and so far I replaced a whole bunch of sensors, heater core flush and fuel pump. Today I was finally enjoying my car took in on a 50 mile hike. Soon as I pulled in my driveway I noticed a slight sight of white smoke coming from the front right side of my car very little smoke. Anyways turned the car off immediatly never overheated I'm religious about checking my temp while driving. Anyways open the drivers door and noticed gallons of antifreeze on the floor coming from the front right side near the right tire. Any suggestions what this can be?
