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

The Thermo switch is located on the left lower side of the radiator. It is best viewed from under the car with the left lower splash shield removed. From under the car look past the drain tube and you will see the brass nut and electrical connector. Thats 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.

WHRE IS THE FAN FUSEE IN A 1.3 TOYOTA TAZZ


you changed the thermo switch and relays and it didnt fix it
did you test the fan motor itself

the fuse box cover should have a fuse layout diagram
engine cooling fan

look for a 30 amp fuse

they usually near the fan relays

is the air con cooling fan working with air con on
and engine running

Left hand driver side fan will not switch on and radiator boils over slightly. Air Con works great. Which relay in the fuse box should I check?


The fan circuit consists of a 30 amp fusible link and a relay in the engine compartment fuse/relay block and the thermo-switch on the little coolant manifold near the driver side end of the engine. The relay is the one on the far right side with the fusible link just below it. I would question the thermo-switch first. To test the circuit you can short the wire that goes to the thermo-switch to ground, with ignition switch on, and the fan should run. It not then check and relay. See the attached diagram for thermo-switch location. Do not take the part numbers on the diagram for gospel. I drew this up several years ago. I do not have my Camry so I cannot totally verify the above. I tried to post an answer several days ago but was not logged in at the time and they would not post it! 310bec86-8097-4e0b-9e5c-c6e4a17e69d4.jpg

I have a vw golf 1996 1.8se adz engine. lately when you start and drive car first thing in morning it drives kangarooey for a couple of miles and then its ok any ideas of the fault


Bad thermo-time switch. This sensor will tell the ECU if engine is cold and will add fuel to the oxygen mixture. When it's in operating temperature it will tell the ECU for correct preset fuel mixture. Also if you have a 5th injector the ECU will know when to shut it off so you won't have a rich mixture. Also visa versa depending on the data it receives from the thermo switch.

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.

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.
