In all probability you either have a bad radiator cap or an air lock.
The normal engine coolant temperature typically ranges between 195°F to 220°F (90°C to 105°C) when the engine is operating under normal conditions. This temperature range ensures optimal engine performance and efficiency. If the temperature exceeds this range, it may indicate issues such as overheating or a malfunctioning cooling system. Regular monitoring of coolant temperature is essential for maintaining engine health.
The engine needs to be flushed.the coolant ports have a build up of gunk causing the engine to run hotter. The heated water expands to much causing it to over flow from the reserve tank.
After coolant is added run vehicle to normal operating temperature and re-check coolant level
White smoke from tailpipe when engine is at normal operating temperature? Oil mixing with coolant? Coolant mixing with oil? Run engine to normal operating temperature remove dipstick and let a drop fall on hot part of engine - oil will smoke coolant will "sizzle" Misfire at 2 adjacient cylinders?
this sounds like a bad thing to me...like the reservoir and/or the cooling system, has no antifreeze in it and heat from the engine is exiting through the cooling system. Does your temperature gauge read in the normal range? Is the car running OK? FriPilot
You may have a faulty coolant level sensor
Depending on the engine, the coolant temperature in a Cadillac could be from 180 to 195 degrees. The thermostat can be changed to give a lower or higher temp reading.
What is a normal operation in city traffic and in highway for corvette 2002 with LS1 engine?
It depends on which model year / engine. The E46 330i operating coolant temperature is about 97 Celsius.

I am an ASE certified technician. Your normal engine or coolant temp should be 190 - 210.
there is a level sensor in the coolant canister located on the inner fender on the pasanger side under the hood. the radiator overflow line goes to this canister. this has happened to me several times on my 2001 Z-71. all i do is add anti freeze to the hot level, after the engine is at normal operating temperature.
