2000 Cadillac Seville STS Question: Coolant leak

CAR LEAKS 2 GALLONS OF COOLANT IN ONE DAY. CHANGED THERMOSTAT AND RADIATOR WAS FLUSHED. OIL DOES NOT LOOK LIKE IT IS MIXED WITH COOLANT. WHAT COULD POSSIBLY BE THE PROBLEM. -
Answer 1
If you have this big of a leak it should be fairly obvious as to where the leak is, and if you can't determine where it is (sometimes it is very difficult) then I suggest having a professional locate the leak. Call some of these shops if you need help: http://repairpal.com/directory?address=21613&car_brand_names=Cadillac -

THANK YOU. I ACTUALLY TOOK IT TO A PROFESSIONAL AUTO SHOP AND THEY CANNOT LOCATE THE LEAK. IF IT'S NOT THE THERMOSTAT OR RADIATOR WHAT COULD IT POSSIBLY BE. YOUR RIGHT 2 GALLONS OF COOLANT IN ONE DAY IS A BIG LEAK. THANKS AGAIN FOR ALL YOUR HELP !!! -

This just doesn't make sense. I suggest taking it to another shop. -

Head gasket failure is common on the North Star. It will consume coolant in that amount. Usuall though you can smell it in the exaust. -
