Is there any way to check if the cooling system fan works without overheating the engine?

Apparently you are having an overheating problem and you suspect the radiator cooling fan. First thing you want to check is if the thermostat is not stuck closed. Open the hood, remove the radiator cap and start the engine. When normal operating temperature is reached, carefully look into the radiator filler neck. You should be able to see water circulating. If the fan motor doesn't come on by that time, then it could be that the radiator fan sensor switch or the radiator fan motor are At Fault (maybe even both). After the engine cools down, wire the fan motor direct to see if it will run, if it does, replace the sensor switch. If the fan motor doesn't run, replace the fan motor before you buy a new sensor. If after replacing the fan motor, the fan still doesn't run, then replace the sensor. You don't have to run the engine to an overheating point to see if the fan will run, it should come on when the engine reaches normal operating temperature.

What are the operations of cooling system?
The cooling system in your car (radiator) cycles fluid (water with anifreeze/coolant) through your engine to keep it from overheating. It carries heat away from the engine.
No ciculation in cooling system and engine overheating what is going on Water does not appear to be circulating and reservoir never warms up. Coolant always cool. Engine overheating.?
Failed thermostat.
Is the Cooling Agent raises engine temp?
No. The purpose of the cooling agent is to maintain the engine temperature within permissible limits to ensure minimal damage to the engine and avoid overheating. The cooling system cools the engine and reduces its temperature.
When do you need to change thermostat on a dodge neon?
If the engine is overheating or when you service the cooling system and change the antifreeze.
If the engine overheats will this drain the air conditioning?
The air conditioning is a separate system from the cooling system and will not be affected by overheating, however if the overheating problem is associated with an inoperative cooling fan or a blockage in the air flow through the radiator and evaporator then the system will not cool properly.
Why is a cooling system required in a motor vehicle?
Because quite a lot of the energy used by a combustion engine gets turned into heat whether we want it or not, so a cooling system is needed to keep the engine from overheating.
What are the causes for engine overheating?
Lack of coolant, lack of coolant flow, air in cooling system, lack of airflow over radiator,........
If one engine management system temperature sensor is faulty how will it affect the engine and what are the symptoms?
