Regarding my 97 Trans Am WS6, with the LT1 engine, the low coolant light on my dash seems to come on intermittently. I have checked, cleaned, and verified a good ground, checked and verified good connections, and I check the coolant level every time the car cools down. I add about a 1/4 to 1/2 quart of coolant every time to top off the radiator, and have bled the air with the bleed screws several times. The light stays off until the engine reaches normal operating temperature, the thermostat opens, and the light comes on. I have checked for leaks and found none visibly, no coolant in the passenger compartment, no white smoke, and the engine runs well. Where is the ccolant going? The oil does not appear contaminated, nor does the coolant. Does this sound like a faulty head gasket, or possibly a cracked block? Thank you.
