If it's electrical. unplug it and try it direct to battery. if it runs, fan is ok, if it does not then replace fan. now, if it's ok, then there's a problem in the circuitry that tells the fan when to turn on. this is usually controlled by the coolant temp sensor.

Did you check sensor also? If service engine light is on take it to Auto Zone they can put it on a tester for free & tell you what it is.

Why does my cooling fans run continuosly?


HI Daniel, The fan operation is controlled by a temperature sensor which is preset to operate a relay. The relay is usually a normally closed relay which when the cable is removed from the sender unit closes the relay and brings the fan into operation. Check the sender unit, the connection and the relay for defective operation. Regards John

Overheating 2003 dodge durango. What could be the problem??


When engine running, ensure no engine combustion gas bubbles in coolant resevoir (if so, the head gasket is blown).

Check cooling fans are operating ok (when required when car warms up), if not check
1) fuse,
2) relay operation,
3) heat sensor switch.

Replace thermostat.
When re-filling cooling system, bleed off any airlock as necessary.

Check for collapsing (soft) coolant hose on suction side of waterpump when engine revs above idle.

I have a 2003 VW Jetta 1.8t that is overheating. Replaced the thermostat, temp sensor, water pump. Fan will run when AC is on, but haven't had it running in hot enough weather to see if the cooling fan...


Assuming engine tune / mechanical condition is not the cause of the overheating:-
Ensure cooling fan is cutting in at the appropriate engine temperature - check operation of the fan controlling relay,
Ensure fan switching control temperature sensor is serviceable,
Ensure cooling system is filled properly, taking care to bleed out air where necessary,
Ensure coolant pressure cap is of correct rating and in serviceable condition,
Check coolant hose on suction side of waterpump is not softened and collapsing at engine revs above idle,
Ensure radiator core is not blocked or cooling airflow inhibited by insects etc.

Overheating


Your overheating problems can have several possible causes.
1) Airlock in heating system - solution - bleed air from cooling system.
2) Radiator blocked - solution - drain and flush radiator
3) Failed waterpump - solution - fit new waterpump
4) Engine thermostat stuck in closed position - solution - fit new thermostat
5) Electric cooling fan (if fitted) failing to operate - solution - check fan, fan operating switch, all wiring and connectors
6) Not enough coolant in system - solution - check and top up to required level. Also check all hoses for sign of leakage.
7) Faulty temperature gauge giving incorrect reading.

Loosing water from my overflow bottle in my lantra 1995 - N reg and the car is overheating. Don't know where the leak is coming from - anyone any ideas?? Please


First, is the radiator fan coming on? If not, you will need to check fuse,sensor, relay and fan motor. Need to check thermostat for proper operation. If all is good, you will need to have radiator flush. Keep me informed and I can guide you so more.

94 buick roadmaster over heating changed waterpump both relayes both fan motors coolant temp sensor and the guage sensor still fans will not come on if i unplug the coolant sensor both fans will come on...


I feel there is a sort somewhere in the fan circuitry, check its fuse unit. Also ensure proper level of engine oil is present in the engine. Actually your car might be overheating because the respective fans are not powering on at the correct time, but you mentioned that these fans are in working condition so it has to on something in this circuit that is preventing completion of this circuit by their respective sensors which you have recently changed...............sodeep

1995 monte carlo overheating


If the radiator fan isn't coming on I would check the coolant temperature sensor which tells the fan to turn on. Check your owners manuel for locations of fuses or relays that control the fan. Lastly you can unplug the fan and direct jumper it to make sure the motor isn't burnt out. I hope this helps.
