Cadillac Repair: caddilac, head gaskets, fluid leaks

Question
my 93 Cadillac seems to be overheating and when it cools down i add coolant and put coolant in the overflow..but a  couple of days to a week later it is low on coolant and overheating?when it is overheating it doesn't blow smoke...what could this be?

Answer
Normal engine temp is 220 to 230 degrees.
Either you are LOSING it externally due to leaks or your using it internally due to numeroud smll holes/leaks in the head gaskets which is pretty normal o=for this engine.

I would suggest that you check the thermostat for proper operation.

Check for any external fluid leaks on the ground.

Check the water pump.

Have the head gaskets pressure tested.
