Near the bottom of the radiator on the engine side there s a drain petcock valve you can unscrew which will drain the radiator and the motor. you can also take the lower radiator hose off at radiator and let coolant drain into pan, connect hose and refill.

1998 cadillac deville , cooling fans for rad will not come on and I already replaced the AC comp relay


The only other things would be the coolant temp sensor or the engine computer. Alot of the new GM's have the on and off function of the cooling fans controlled by the computer. If the coolant temp sensor is ok, then most likely the problem is in the engine computer.

1998 cadillac deville looses about 1/2 collant every two to three weeks no coolant in the oil or on the ground


Check for possible leak. Also check the radiator cap. Inspect the rubber seal for signs of deterioration. Look for signs where coolant had been escaping which would have coolant stains on them.
