Your most likely cause is a sticking relay or a short to power. Don't discount the fact that the short to power can occur inside of the electric fan motor!

My fiat Doblo cooling fan stays on when engine is switched off


A significant number of cars have an electric cooling fan supplied by a battery live rather than an ignition live because it is believed the cooling fan should be able to start or to continue running after the engine has been switched off.
Coolant will continue to circulate after switch-off due to thermo-syphon activity and it could reduce mechanical stress on engine components to continue cooling.

Some people modify the cooling system by fitting an additional manual switch to over-ride the thermal switch for use when standing in traffic, for whenever continuous operation is desired or to use in emergency should the thermal switch operation fail.

In the absence of such a modification that has been inadvertently switched on the fault will be due to a faulty thermal switch, a faulty or stuck relay or shorted wiring. Disconnecting the thermal switch should stop the fan and if it does it indicates the switch is faulty. The switch is mostly fitted into the radiator header tank but sometimes is fitted to the bottom tank or the thermostat housing.

Cooling fan keeps running after engine turned off on a 1996 ef ford falcon


Some fans do keep running after engine is switched off for a short period of time (up to 5 minutes) Check with a service person (ford) to see if that is the case or if you have a faulty sensor.

Cooling fan runs continuously, even after shutting the ignition off


sounds like it could be a relay.

With everything plugged in and the fans running with the key off remove the cooling fan 1 fuse. Do they stop?

If they do not stop remove the cooling fan 2 fuse. Do they stop?

I have a 86 camaro 2.8L run good till it gets warm then die's won't start again till it cools. getting fuel and spark.


I have a 1985 Camaro and if the switch for the fan is off then it overheats. There is a fan that can be installed. My switch is on the left of my steering wheel. Tune up is always good. Have your alternator checked, if it's old can be a problem maybe. New spark plugs can't go wrong. Good Luck!!!

Cooling fan continues to run after engine shut off.


The fan runs for a short time, after ignition off, to continue to cool the hot engine.

Cooling fan continues to run after turning off ignition


For how long does the fan run after you remove the keys from the ignition?
It is cooling your system... but for how long. Too long will drain your battery. There is an sensor on the engine that activate the fans. If the fans are running more than 3min, change that sensor. Also check to see if you have enough antfreeze in the system. If not enough.. the cool fluid won't reach the sensor to signify that the system is cool.
Check fluid first, then the sensor

1991 honda accord lx cooling fan


Some vehicles have sensors that can control the electric fan with the ignition off to keep the heat buildup that naturally occurs right after turning off the engine. This can prevent hard starting that can happen with a hot engine. If it is doing this an abnormal amount, the sensor that is operable with the ignition off may be failing. Before turning off the ignition, check to see if the engine temperature is pushing the 'red zone;' if it is, then the fan operation may be normal but your engine may be running hot.

Fan continues running after turning off ignition


HI. This will, generally, be the result of the cooling fan switch.

The cooling fan switch on most electric fans monitors coolant temperature signals from the engine control computer. When the engine is cool, the switch opens to keep the fan from spinning. When the engine is warm, the switch closes, thus, turning the fan on for cooling.

I would advise to Inspect the cooling fans(thermal switch),wires and connections. Cooling fan switch problems are often caused by faulty wiring or loose or corroded connections rather than the failure of the switch itself. If the wires or connections are bad, replace them. If you think the switch is defective, it should be tested.

The electric fan cooling switch, or thermal switch, can be tested by placing the element in a bucket of water. Heat the water to approximately 207°-216°F (97°-102°C) and connect the switch leads to an ohmmeter(make sure to keep the switch leads out of the water). The switch should have no continuity until the temperature reaches this level. Let the water cool off below 207°F (97°C) and the switch should lose continuity. If the switch has no continuity at any temperature, replace it.

NOTE_The thermal switch is located on the top of the radiator, usually on the passenger side.
