When I start my car the fans that cool the engine temperature always run even though the engine is still cold. I have replaced the relay for it in the fuse box but this didn't correct the problem How do I fix this? Thanks Rui

Hi
Are the fans running all the time??
Remember the thermostat does NOT control the upper temperature of the engine, the rest of your cooling system does.or chek the connections and the temperature sensor.
If you want a cooler running engine you will have to increase the capacity or efficiency of the cooling system.
This may be as simple as cleaning the rad., inside and out. Or replacing the air dam. Or as complicated as redesigning the entire system.
But it sounds NORMAL to me.
chek this site for airdam

    The fan relay may be malfunctioning (the fan relay is what actually switches the fan on and off and gets its signal from the ECM, which in turn gets its signal from the temp sensor) testing/replacing the relay and temp sensor would be the best thing to start with,... unless you notice any additional (non factory) wire attached to the power wires to the fan. Sometimes folks, in an attmpt to fix an overheating or fan relay problem, attach a ignition switched positive lead from the fusebox or other switched source to the positive poer lead on the fan,.. making the fan run whenever the ignition is switched on.

    Try searching for a wire that goes from the fan to a another electrical sourse that is only live when the vehicle is running. Like the coil, distributor.

    OR adjust the settings of the fan..try this steps

    Modify Tune
    Modify Parameters
    Cooling Fans AC off
    Adjust High mph and Low mph fan settings
    - High MPH HS 193
    - High MPH LS 185
    - High MPH MS 193
    - Low MPH HS 193
    - Low MPH LS 185
    - Low MPH MS 193
    Push the left arrow to back up 1 level
    Cooling Fans AC on
    HS 193
    LS 185
    MS 193



    all the best

    Goodluck

When I turn the engine off the engine cooling fan stays on and does not shut off


depending on the engine temperature the fan is supposed to remain on after you turn the engine off, until the engine reaches a preset cooler temperature. when it reaches cooler temperature usually within 5 minutes or so it should cut off... if you cut it off and it is running 30 minutes later.. then there is a problem with the fan relay or temperature sending unit.

Cooling fan relay


If the fan runs all the time, even when the engine is first started up and cold, then you probably have a bad temperature sensor switch. When that sensor fails, it keeps the fan on all the time so the car will never overheat...Chris

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.

I have a Prelude '97. It overheats. I replaced the readiator, water pump, and one of the fans, but it still overheats when going uphill or when in slow traffic. I've noticed that the fan that is...


will try to help. the fan you replaced, was it the air conditioner fan? if so. then you need to check your primary fan. the one that does come on when the engine reaches operating temperature. make sure by starting engine, let the motor run and the temperature guage reaches the normal operating temperature.if the main engine cooling fan does'nt come on, then you'll need to check the fuse box under the hood. relays are black square plug in's they are marked and will[fan relays] tick when you turn the key on] if main engine fan does not come on when engine overheats, #1 fuse blown #2 relay bad #3 main cooling engine fan bad. note; the air conditioning fan will come on with engine running,when air conditioniing is turned on. when the a/c is turned off, the a/c fan will not be turning. hope this helps and as always, thank you for choosing fixya.com

The radiator cooling fan is always on ?


Is your AC on (AC compressor activated)? Try switching that off and see if it still runs.

The radiator cooling fan is not working. Upon


assuming fuse and relay are good..no fan should be running when the engine is cool/cold, the only time the fan should be running when it reach over operation temperature which then the fan kick on to bring the temperature back down to it operation temperature. both fan work in sync with one another, addition cooling is needed when the ac is running. when the last time have you replace thermostat and Thermos sensor/switch. I would replace both unit if you have not done so. The thermos/switch will turn the fan on when it reach certain temperature and cut off when it sense the temperature drop in the engine.

Vw cooling fan problem?


There is a relay located near the top or side of rad saddle or fan shroud, trace the wiring harness from the fans to this relay sounds like the relay is fused together or shorted out, or as simple as checking your temperature control setting inside, if you have a/c and have the fan set to any position other than off, and the hot/cold dial is in the blue those fans will always be running when engine is. Easy to check this, just have the car running and turn off your fan or turn your temp selector to max hot. If the fan still runs even when the engine is cold then revert to my first check on the fan relay.

AUXILIARY FAN ALWAYS ACTIVATED


if you have your a/c or defrost on the fan will come on as the a/c cuts it on to cool condensor.
if they are not on then you have a relay sticking or someone has rewired the fan

Fifteen minutes! you have bigger problems than only the fans the fans are controlled by a thermo switch that is heated by the coolant, If you have no coolant the sensor cannot activate But fifteen minutes seems like you may have a headgasket problem and steam cannot heat the coolant sensor.OperationNotesThe electric cooling fan operates when the engine cooling temperature exceeds a certain value. The cooling fan on this engine is controlled by the Powertrain Control Module (PCM) . The PCM turns the cooling fan ON by grounding the coil of the cooling fan relays when certain conditions are met. When the A/C is requested, the cooling fan will also be turned ON.

Power for the cooling fan motors are supplied through Maxifuses(R). The cooling fan relays are energized when current flows from the fuses in the Underhood Accessory Wiring Junction Block, and through the relay coils to ground through the PCM. The Coolant Fan 1 Relay Control Circuit is grounded for low speed fans operation. During low speed fans operation, both fans run at a slow speed. The Coolant Fan 1 Relay Control Circuit is grounded for high speed operation. During high speed fans operation, both fans run at high speed.

IMPORTANT: When certain Diagnostic Trouble Codes (DTCs) are present, the PCM may command the cooling fans to run all the time. Perform the A Powertrain On Board Diagnostic (OBD) System Check prior to diagnosing the engine cooling fans.

For more information regarding the Charging System, refer to Charging System Description , and Charging System Circuit Description in Starting and Charging.

If a problem that involves the low speed cooling fan relay control circuit exists, DTC P0480 Cooling Fan Relay 1 Control Circuit should set. If the problem affects the high speed cooling fan relay control circuit, DTC P0481 Cooling Fan Relay 2 Control Circuit should set. A problem with the ECT sensor should set DTC P0117 Engine Coolant Temperature (ECT) Sensor Circuit Low Voltage, DTC P0118 Engine Coolant Temperature (ECT) Sensor Circuit High Voltage, DTC P1114 Engine Coolant Temperature (ECT) Sensor Circuit Intermittent Low Voltage, DTC P1115 Engine Coolant Temperature (ECT) Sensor Circuit Intermittent High Voltage. Any of these DTCs will affect cooling fan operation and should be diagnosed before using the Electric Cooling Fan Diagnosis.

For more information regarding the Cooling System refer to Engine Cooling Fan Description - Electric, and Cooling System Description in Cooling System.
