If the fan is turning slow measure the voltage at the fan connector, if it is at or above battery voltage then the fan motor is shot, replace it. also verify the connector is not burnt looking which is a common problem.

What is the cost of the Coolant temperature sensor?


coolant temp sensor prices vary according to the make and model
they start at around $20.00 and can go as high as $100.00
the purpose of the sensor is to read coolant temp and then through several fuses relay that information to the ECM that then closes a fan relay and puts the electric fans on and also adjust air fuel mixture for engine temp
items to check , fuses , relay
if you fan is mounted and driven by a fan belt , from your problem description , there is every possibility that the viscous fan hub(fan clutch ) is faulty and in need of replaceing

The fan on my 2005 chevy malibu is slow to react and takes a few minutes to start working


If your talking about the cooling fan for the radiator, if it's an electric fan then it is controlled by a temperature sensor that's screwed into the block (usually near the thermostat housing) the fan shouldn't come on right away, until the temp is reached, then it should turn on & run for a while til the temp drops again,then it will turn off, then repeats itself. If this is what's happening then that's normal, if not check the temp sensor.
Now if it's a clutch fan (not electric) then the clutch that's bolted to the fan could be your problem. hope this helps.

Engine coolant fan wont come on. The fan motor is fine. whats next?


You still have many other components in that system that has to be in working order for the cooling fan to work properly. The cooling fan is turned on when engine temp reaches a predetermined temp, usually around 220-230 degrees F. the ECT (engine coolant temp) sensor siganls the ECM (Engine Control Module) to ground the cooling fan relay or cooling fan module(if equipped) and if the cooling fan fuse is good and the fan has power to it the realy will complete the ground for the fan to run. You may need to have a qualified technician diagnose the problem if the obvious things like fuses and good grounds are not the problem.

Hope this helps.

2008 ford expedition air conditioning problems


the ac pressure depends on the gas in use
r314 runs at high pressures
overheating at slow speeds indicate an inefficient coolant fan and the high ac pressures indicate that the condenser fan also is not operational
if it has a viscous fan hub , replace the fan hub
if it has electric fans check / the fans, fan relay , fuses , coolant temp sensor

1998 mazda protege radiator cooling fan not working?


Hi, here is how your system works. The coolant temp sensor get's a reference voltage from the PCM and returns a voltage corresponding to the temp. The PCM then turns on the fan relay onve the temp reaches a certain level. If your coolant sensor is working properly (moving into red or light coming on), then the problem is with the relay, fuse, or the fan itself. Otherwise, it is the sensor.
If the sensor reading is bad, first check the connection to the sensor. If the connection is good, remove the connector and use an ohmmeter to check the resistance of the sensor. It should be as specified below. If not, replace the sensor.
If the sensor indications are good, try swapping the fan relay with another similar relay. The fan realy is usually in a box under the hood--sometimes on the passenger side in front of the shock tower. Finally, if both the relay and sensor are good, use a 12 volt test light or voltmeter to check for power to the fan connector when the engine is running and hot. If there is no power, check the wiring from the fan relay. If there is power, replace the fan motor.
Please let me know if you have any questions, and thanks for using FixYa.

WELL SOME OF THE OLDER CAR RUN A LITTLE HOTTER THAN NEWER CARS THE COOLANT FAN WOULD TURN ON AROUND 180 TO 190 DEGREES.THE OLDER CAR I REMEMBER THE OLDSMOBILE AND PONTIAC ENGINE RUN A LITTLE HOTTER BACK WHEN I OWN ONE.

2002 Millenia, over heats when idling for 20 mins or more, have not seen either (2 cooling fans) go on. One fan truning by hand moves freely and the other it is difficult to move.


Possibly a siezed fan, disconnect fan plug, run a wire from positive (+) battery terminal to fan and same on negitive (-) terminal, to the pins on the fan side of the plug dont touch them together while connected to battery, if fan goes it may be a coolant temp on the engine. bypass temp switch with a loop wire on to wiring harness side of the temp switch. Both fans usually only operate when a/c is on.

I'm still asking questions but here's how it works...temp sender sends signal to the computer which in turn sends signal to the fan. Only time fan is on full time is with a/c. when in motion, you do not really need a fan because vehicle speed allows more air flow than fan can provide. When driving slow (relative to ambient temp) fan comes on as necessary. If fault is temp sender, wire, ground or real;y the computer sees the incomplete circuit. you need to check to find what isn't allowing power flow to fan. (computer receives low voltage from sensor and completes relay ground...relay sends power to fan. IGNORE BUG PERSON that replied...that is not a fix ya expert...its a spammer!!!!
