The gauge should be showing a minimum 195 with engine warmed up. I would start with replacing the thermostat.
During winter, the coolant in your engine may be contracting due to cold temperatures, triggering the low coolant signal. When the temperature rises above 30 degrees, the coolant expands, which could alleviate the low coolant signal issue. It is recommended to check the coolant level and address any leaks to prevent potential engine damage.
Sounds like your coolant is low or your coolant level sensor could be sticking closed after the coolant was low. with the dexcool coolant it becomes thick and cause the sensor to stick closed.
Could be a failed engine coolant temperature sensor. Easy enough to replace and not too expensive.
The curve showing the relationship between temperature and time for a given amount of liquid heated at a constant rate is called a "heating curve." This curve is mapped out on a graph.
Have you had the coolant temp sensor checked? It might be that the engine is running hot but the sensor isn't showing the temp is hot.
A map showing temperature is called a thermogeographic map or an isotherm map. It represents temperature variations across a specific region or area.
On a 1995 Buick LeSabre, the temperature gauge is located on the instrument cluster, which is situated on the dashboard behind the steering wheel. It typically appears as a dial or indicator, showing the engine coolant temperature. If you're looking for the actual temperature sensor, it is usually found near the engine, typically on the cylinder head or intake manifold.
Eather temp senser or thermostat.
Either the coolant level is low and needs topping up, or more likely that the sensor is faulty. Experience shows that for ever 10 cars with that showing 9 have a fault with the sensor. Check the level anyway!
It is a heating curve. It shows the temperature changes over time as a substance is heated continuously at a constant rate, highlighting phase changes and plateaus in temperature where energy is absorbed to overcome intermolecular forces.
If you are not getting heated air blowing from the heater core and your engine coolant temperature gauge is showing LOW or below normal , ( then YES , IT'S POSSIBLE that your engine cooling thermostat is sticking open )
