I have a unique situation I think. I have a 1995 Olds Cutlass Supreme. When I drive it after a few minutes, the Thermostat shows HOT. After a few more minutes, it bounces back to medium. At that moment, in cold weather, I would get a blast of heat. Up to that point, my heater wasn't working. Then the cycle repeats, all the way to HOT, a blast of heat from the heater, then back to normal again. Over the past few weeks, I've added coolant 50/50 mix almost daily. I can spot no leaks anywhere. My buddy is a gearhead and he cannot figure it out either. The thermostat has been replaced and both fans on the radiator work.. Any ideas??

the heating up and then cooling sounds like the t-stat opening and then closing, on that engine the intake manifold leaks are generally external, if the engine is losing that much coolant internally you should smell it or something, i would check for leaks where it can hit exhaust or something that lets it evaporate without seeing it, sometimes the radiator will have a small hole that lets coolant leak, but drys before dripping

Need to replace the water pump and check where the fluid is going , Examined the tail pipe for antifreeze, If you find antifreeze then you have a head gasket blown be careful about driving very much, hope this helps.

sounds like an ontake manifold gasket or head gasket problem when they leak you get air in the system the water pump can not pump air amd also the temp sensor can not read properly when it is surrounded by air and not coolant these motors are known for these problems good luck it may be better to get a new car than spend around 1200 on a 1995

Most likely, your cooling system is getting exhaust gasses via a bad head gasket.
To check this, start the car. MAKE SURE THE ENGINE IS COLD. Remove the radiator cap and rev the engine. If your coolant foams and surges, you likely have a bad head gasket.
A little surging is normal, but if it gets foamy (lots of tiny bubbles) its getting exhaust gasses via the head gasket.

Keep adding fluid. Once you open up the cooling system you allow air to enter. The is most likely air trapped, therefore no fluid is visible.

Could your heater core be bad? That's the next thing I would check. Or bad water pump.

if your losing fluid and not finding any leaks you might have a head gasket leak. the enging is actually burning the leaking fluid.
