Radiator Fan's Run All The Time

My son's 2001 Pontiac Grand Am has constantly running cooling fans, even in this cold area of Michigan. As soon as the engine starts the fans come on and stay on until it is shut off. The A/C is not on. At just about the same time, the temperature gage quit working - stays buried at the left - as it would with a cold engine. Finally, the service engine soon light is lit up. Could it be as simple as the temperator sending unit? Thanks

There are 2 things that will cause this to happen. 1. The thermostat needs to be replaced and, 2. The coolant sensor can be bad. When I had this problem, I changed them both at the same time, she been just fine since then. Also, I had the check engine light on, and got the code from AutoZone (it's free!)

2004 sunfire cooling is always on when the car is running


The cooling fan is controlled by a temperature switch located on the radiator or on the engine. When the temperature of the coolant exceeds the switch temperature rating, the switch closes and energises a relay that switched a voltage to run the fan and it will continue to run until the coolant temperature drops back below the opening point of the switch. In your case, you may need to have the cooling fan replaced.

2001 Jeep Laredo has 2 fans at the radiator - are both fans supposed to run all the time?


Hi,
The answer to that is NO!
There are two fan motors on that area. One is for the radiator cooling system and the second is for the condenser( Airconditioning system ).
The radiator fan starts/run when the engine temperature reaches a certain temperature( electric thermo switch on the radiator ), while the A/C fan starts whenever you switch on the a/c.
Hope that clears up everything.
Thanks for asking FixYa!

Even if my 2008 grand prix is completely warmed up, when I turn the fan on it only blows cold air.


Could be air in cooling system. Add antifreeze to cool radiator, run engine, cool, check level again, until completely full.

95 grand am radiator fan only runs with AC on


Cooling Fan Temp Sensor is the First thing You Check (with what you have described) Cooling Fan Should ALways come On When The A/C is turned On as A/C Adds A Load to Engine, If Temp Sensor is Faulty it Will Not Give GROUND Signal to ECM >For COOLING FAN >RELAY to Give ground and turn ON The Fan.
There ARE 2 temp Sensors that Serve Different Purposes 1 is for Dash READING GAGE & Or TEMP LIGHT the Other is For ECM or Fan Relay (SAME Thing) you Said>""can disconnect the sensor and fan continues to run" < This Leads me to think you Changed the Wrong One. Not Questioning your Skills Just Here to Help.
TEMP SENSOR FOR 3.1L V6 is Located upper RH rear of engine compartment, near exhaust system. Temp SENSOR for 2.3L Engine is Located in LH rear of engine compartment.
I Hope this Helps Lead you to a NON-OVERHEATING Pontiac.
Good Luck and Have A Great Evening. rejakwilson
