Hey guys. I have a 2008 CTS here, direct injection. I’ve noticed over the past year my coolant level has gotten low. I will fill it, and it’s low again, repeat. I had to replace the water pump twice, but this time around I have seen no leaks around the pump or anywhere else and oil level appears normal. Where is the coolant going? Could the radiator be failing since I have about 110,000 miles on it and maybe I haven’t noticed any coolant because it’s burning off on the radiator?
