SOURCE: thermo fan on radiator wont turn off

It wont hurt anything if they stay on all the time cus the fan will mostly runs off your alternator. But if does bother you then it meant be the sensor on the fan. Or you can install a switch to turn the fun off and on with a toggle switch. But its up to you. But for the most part as long as the fan keeps going to cool off your radiator you should be ok. But i am thinking it maybe the sensor not telling the fan to shut off and turn on when its suppose to.

SOURCE: Cooling fans on radiator will not run. Voltage in

Our problem was to establish if we had a line resistance from the fan relay to the thermo switch or an intermittent earth connection. Neither was the answer.
We managed to locate a circuit diagram off the web and discovered that the fan relay is controlled by the ECM. The ECM gets data from the thermo switch and that is a 5 volt circuit.
We found a guy about 2 miles from where we are in New Zealand who has an electronics workshop who has had this happen before and repairs ECM's for a living. He will get it monday to do that.
THe original problem was that the two hoses that come from the block to the heater blew simultaeniously. Couple of plastic connectors broke. Fixed those and tested all fine and two days later popped the pressure cap. At this point found the radiator fans had been intermittent and finally failed completely. Cant find any other damage so will thow in a new thermo stat an a repaired ECM anfd go from there.
regards
Dave

SOURCE: Where does the radiator fan switch -thermo switch

Facing the front of the car, on the right side radiator tank, it is located at the bottom of that side tank. There is a three prong plug with a black boot on it.

My fans will not turn on my 1999 Monte Carlo Z34


check the thermo switch on the radiator use some wire and connect the pins, if the fans come on then change the thermo switch, if they don't come on then the relay needs replacing. thermo switch works off negative feed so there should be no sparks if their is a spark then the electrics is a problem.

My car starts an runs but the radiator fan is not coming on and it over heats fast. But the warning lights don't pop up on the dash board


f the engine shows signs of overheating, stop and look to see if the fan is working. With the type operated by the Connect the motor feedterminal to the live terminal onthe battery.

Check a fan motor for faults

Fan motor with the thermo-switch lead disconnected and test lead connected to the battery.Look at the battery, and take off the wiring terminals to the motor or disconnect the plug. Free the wires from clips or other fixings on the fan
A new motor is supplied without a fan, which must be refitted from the old one.The motor and fan normally come off as an assembly, but you may also have to remove the shroud and sometimes the radiator.
Separate the components. Clean the parts that are to be reused, simply by degreasing or even by repainting.
Checking the new motor When you fit a replacement motor, check it by connecting its leads directly to the battery. Be sure to connect the positive (+) and negative (-) leads to the corresponding battery terminals.Take care - the motor will kick as it starts and there will be a large spark when it is connected.
Checking the switch for faults A thermo-switch with push-on connections. The switch is threaded and has a sealing washer which must be renewed.If the fan motor is not at fault, leave the ignition switched on, take the connections off the thermo-switch and briefly touch them together.
If the fan motor now works, the switch is faulty. If it does not, check to see that there is current flowing to the switch by using a circuit tester on the feed wire to the thermoswitch.
Touch the leads together to bypass the switch.If the tester does not light, trace the lead from the thermo-switch back to its power supply; the car handbook may have a wiring diagram
A detailed drawing showing the location of electronic components and devices that are connected together in a circuit.
.If the tester lights, trace the lead from the thermo-switch through to the relay and check the terminals for tightness and cleanliness. Clean and tighten as necessary. Changing a thermo-switchThe thermo-switch is normally located in the radiator bottom tank, in the How to flush an engine radiator) until the coolant is below the level at which it is fitted. Catch the coolant in a clean container if you plan to reuse it. If a rubber cover is fitted over the back of the switch, ease it off, then disconnect the electrical connections.
The switch can now be unscrewed from its mounting point with an appropriate spanner. It may, however, be very tight, so take care not to distort the surrounding metal if it is fitted in the radiator bottom tank. Always fit a new sealing washer.
Checking the relay for faultsWith the ignition switched on, short-circuit the thermo-switch by putting a screwdriver across its two terminals; do not disconnect the leads. You may be able to hear a click from the relay as it operates. Test for current with a test lamp or circuit tester at the 'live' lead to the relay - again with the ignition switched on.
If there is current here but, when the thermo-switch is bypassed, none at the terminal for the fan-motor lead, the relay is faulty and must be replaced.
Checking the T-piece On the Datsun Cherry the thermoswitch and connections are in a T-piece on the bottom radiator hose, so look there if the switch is not on the radiator.

Radiator fan doesn't work


Always keep an eye on your engine temp gauge, find rad thermo switch and bridge connection (it's a switch anyway) this should bring on rad fan. Thermo switch usually on thermostat housing or radiator body housing !

Cooling fans on radiator will not run. Voltage in plug at block thermostat is 5.4.this therm provides an earth switch. Bypassed the thermo to earth and fan relay engages momentarily only. Relay is ok....


The fan control thermo switch should be either "off" or "on".
Voltage should measure either +12 or 0V, depending on coolant temperature.
Replacing it should fix your problem.

Auxiallry fans on radiator dont seem to come on. how do they work


Hi, They are controled by a thermo-fan switch, when coolant reaches a certain temperture fan switch turns on radiator fans and brings temperture back down. Thermo-Fan switch is located bottom of radiator.

Fan motors


Check that the fans are still working .Check that the thermo switch is working.Check that you have power to the thermo switch. and if not check relay/supply of power.Unsure with your model but the thermo switches are usualy screwed into the radiator but could be mounted on the engine.You can check your fans by running a piece of wire from the positive terminal of the battery to the positive side/wire of the fans.As long as the fans are earthed as well they should work and if not then the fans will need to be replaced.

1998 Volkswagon Beetle - Overheating


Hi,

To my knowledge, the thermal switch is normally located attached to the radiator. This senses the coolant's temperature inside the radiator and upon reaching a predetermined level switches on the radiator fan. Further, to my understanding, either the A/C or the heater must be engaged for the fan to activate.

As to your other concern, overheating; In my country, most overheating issues on Volkswagen models are resolved by:
  • entirely removing the thermostat (not applicable in cold regions);
  • wiring the fan to switch on once the engine is running (with or without the A/C or heater being turned on);
  • replacing the radiator thermal switch for the fan to a lower temp.
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards. Thank you for using FixYa
