stop an engine
If it's overheating, it cold be thermostat, radiator or possibly other problems. If it's not overheating it could be the coolant level sensor.
No coolant Thermostat not opening Defective temperature sensor
A thermostat that is stuck in the closed position is a very common cause of overheating. A new thermostat should be installed every time the coolant is changed.
Overheating is due to, well, the coolant in the cooling system getting too hot. In a normally operating engine, this should never be a problem. First, check that the coolant level is correct. If it is correct, I would suspect a problem with the thermostat. When the engine is cold, the thermostat closes off coolant flow through the engine until the coolant reaches a pre-determined temperature. When that temperature is reached, the thermostat opens to allow the coolant to circulate at that exact temperature. Thermostats are known for failing and either not opening or not opening enough at that pre-determined temperature. This causes coolant to get trapped too long in the engine coolant chambers, heating it beyond limits, causing the engine temperature to increase and possibly overheat. If my Maxima was overheating, I would check the coolant levels and then possibly replace the thermostat. It usually is no more complicated than that.
No thermostat, no coolant, no waterpump. Basically you have no coolant circulating.
Yes it can. A faulty thermostat can cause overheating which will cause coolant to be pushed out of the system.
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.
"COOLANT THERMOSTAT" -COOLANT TEMP BELOW THERMOSTAT TEMPERATURE
Low coolant, bad coolant tank cap, stuck thermostat, or clogged coolant line.
Blown head gasket?
That happens because the engine is overheating. Normal causes are low coolant, bad thermostat, or inoperative fan.
The Engine Coolant Temperature in the Engine is higher than it should be. Check your radiator coolant level - also your radiator may be clogged or thermostat may be stuck.
