Oil/antifreeze mix is usually caused by head gasket leaks or valve cover gasket leaks.
Thermostats determine when antifreeze enters the main cooling system. If the thermostat isn't working correctly, the antifreeze could enter the engine to late, (or not at all) resulting in an over heating engine. Another problem of having antifreeze enter the engine late, is that if your engine is very hot, possibly a little warmer than common, when the antifreeze enters the engine, the cold fluid could cause the engine block to cool down quickly, causing a cracked engine block.

No, but faulty water pump or thermostat can.
There are a few things that could be causing your 200 BMW 528i to overheat. You may not have the correct mixture of coolant in the vehicle. The problem could also be your thermostat. Have the thermostat checked out to ensure that it is working as it should.
By itself, the thermostat would have to be stuck closed causing a severe overheat condition to cause a loss of power.
If the thermostat does not open, it will prevent the coolant from circulating through the engine properly. This can result in the engine overheating and potentially causing damage. It is important to replace a faulty thermostat to prevent engine issues.
start by replacing rad. cap. if that doesnt help you have a blown headgasket.
You could have a stuck thermostat or your cooling fans aren't working.
The coolant is not flowing, causing no heat. Look at the antifreeze coming out to see it there are bubbles in it. If there are bubbles then you have a blown head gasket. If not, then you have either a bad thermostat of bad water pump.
To determine if the thermostat or the cooling fan is causing your 1993 Dodge Spirit to overheat, start by checking the thermostat. Remove it and place it in boiling water to see if it opens; if it doesn’t, it needs replacing. Next, check the cooling fan by running the engine and observing if the fan activates when the engine reaches a certain temperature. If the fan doesn’t turn on, it may be faulty or there could be an issue with the relay or wiring.
It sounds like the thermostat is opening up late causing the engine to almost overheat before it opens. Replace the thermostat.
could be fans not working, thermostat, blown head gasket, broken or leaking coolant lines, bad heater core
