Question about 1991 Chevrolet Beretta

Engine cooling fan will not turn off

I have a 1991 Chevy Baretta (2.3L) and as soon as the ignition switch is turned on the engine cooling fan starts, and continues to run as long as the switch is on. This happens even when the temperature is below freezing.
Is the fan controlled by a temperature switch in the cooling system, and if so, is this the part I should look to replace ?

You need to look under the hood and to make sure someone did not wire the fan direct to your ingnition switch because they did not wanted to replace the fan because the relay was bad in the fan.

It is controlled by the Coolant Temperature Sensor. it is located on the engine by the thermostat housing. It is brass colored with a small plug going to the fans.
Did you recently change your battery or otherwise remove the battery ? Sometimes it has happened that the battery is removed and the fan will turn on and the check engine light.You can try and remove the negative cable wait a minute , then reconnect it back,.

95 chevy baretta ran out of gas now wont restart with plenty of gaz


You need to check if the fuel pump (in the gas tank) is still turning on to put gas up to the engine. It's been known to happen that running out of gas can burn out the fuel pump. Manufacturers put the pump in the tank so the surrounding gas will keep the pump running cool.

As soon as i turn the key on(without starting the engine), the radiator and a/c fans starts.


This sounds like the heat sensor in the engine cooling system is failing/has failed completely (internal switching contact remains closed). The engine cooling fan should only come on at the prescribed heat temperature but will also remain active after shutting the engine down, if the engine temp is still above the prescribed temp. Regarding the A/C fan, this is most likely a wiring fault, possibly a short circuit with the car's ignition circuit.

don't push your luck, engine is overheating, check if cooling fans are working, to check jump wire fan direct to battery, fan should run if good. if it does, cooling fan switch maybe defective. one on engine and one on bottom of radiator. replace if need be.

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.

91 honda accord fan stars when you shut off engine


There are two fan switches on that car;
The main one turns the fan on and off when the ignition is on and the car is running.
The second switch powers the fan if the ignition is off and the engine temperature is too high, to cool the engine off if it was just shut down.
It sounds like your main fan switch has gone bad and needs to be replaced since it's not sending any signal to the fan, while the engine is running.

2003 Chevy Impala, running hot. Changed fan shroud because cooling fan wouldn't turn on, switched out fan relays, no check engine light. Cooling fan still will not turn on.


Would turn the key on no need to start it and unplug the ect engine coolant temp sensor. If fans come on then suspect a faulty etc which may not turn on the engine light. Which engine is in the vehicle so I can help locate the ect which is usually by the thermostat housing.

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.

Engine cooling fan not cutting in Peugeot 206 2002 Cooling fan and motor have been replaced with main dealer parts


Try the cooling fan switch, it looks like a large brass nut with wires on it on the thermostat housing or radiator.
To test, pull off the wires and connect together, turn on ignition and the fans should cut in.
If they don't it could be the relay, fuse or broken wire.
The switch is easy to replace, unscrew and rescrew in the new one. Connect the wires, not important which way the wires go, and refill coolant.
